To find 576 ÷ 49 using repeated subtraction, we repeatedly subtract 49 from 576 until we can no longer do so without going below zero.

1. Subtract 49 from 576:

– 576 – 49 = 527
2. Subtract 49 from 527:

– 527 – 49 = 478
3. Subtract 49 from 478:

– 478 – 49 = 429
4. Subtract 49 from 429:

– 429 – 49 = 380
5. Subtract 49 from 380:

– 380 – 49 = 331
6. Subtract 49 from 331:

– 331 – 49 = 282
7. Subtract 49 from 282:

– 282 – 49 = 233
8. Subtract 49 from 233:

– 233 – 49 = 184
9. Subtract 49 from 184:

– 184 – 49 = 135

10. Subtract 49 from 135:

– 135 – 49 = 86

11. Subtract 49 from 86:

– 86 – 49 = 37

12. Now, we cannot subtract 49 from 37 without going negative.

We can count how many times we subtracted 49: we subtracted it 11 times.

So
