72617531 ÷ 961 
Our goal is to divide 72617531 by 961.

Step 1:
961 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 961

On to step 2:
961 can be fit into 72 0 times, resulting in a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 961

Let's proceed to step 3:
The number 961 fits into 726 0 times, leaving a remainder of 726.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 726, we get 726.
Take the next digit (1) from the dividend and append it to 726, then repeat: 7261 / 961

On to step 4:
The number 961 fits into 7261 7 times, leaving a remainder of 534.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 6727 from 7261, we get 534.
Include the next digit (7) from the dividend after 534, then repeat: 5347 / 961

Going ahead to step 5:
If we divide 5347 by 961, we get 5 and a remainder of 542.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Deduct 4805 from 5347 and we're left with 542.
Append the next digit (5) from the dividend to 542 and continue with: 5425 / 961

Step 6:
5425 divided by 961 is 5 with a remainder of 620.
Use 5 as the next digit of our solution. 
Result so far: 755.0
If we subtract 4805 from 5425, we get 620.
Fetch the next digit (3) from the dividend, attach it to 620 and continue: 6203 / 961

Step 7:
If we divide 6203 by 961, we get 6 and a remainder of 437.
Write down 6 as next digit of the result. 
Result so far: 7556.0
If we take 5766 away from 6203, we end up with 437.
Fetch the next digit (1) from the dividend, attach it to 437 and continue: 4371 / 961

On to step 8:
The number 961 fits into 4371 4 times, leaving a remainder of 527.
Put 4 as the next digit of the answer. 
Result so far: 75564.0
Subtract 3844 from 4371 to get 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Advancing to step 9:
If we divide 5270 by 961, we get 5 and a remainder of 465.
Record the quotient 5 as the next digit in the result. 
Result so far: 75564.5
If we take 4805 away from 5270, we end up with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 10:
961 goes into 4650 4 times with a remainder of 806.
The next digit of our result is 4. 
Result so far: 75564.54
Subtracting 3844 from 4650 leaves us with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Let's proceed to step 11:
When dividing 8060 by 961, we get 8 with a remainder of 372.
Use 8 as the next digit of our solution. 
Result so far: 75564.548
Subtracting 7688 from 8060 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 12:
When dividing 3720 by 961, we get 3 with a remainder of 837.
The number 3 becomes the next digit in our result. 
Result so far: 75564.5483
Subtracting 2883 from 3720 leaves us with 837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

Step 13:
The number 961 fits into 8370 8 times, leaving a remainder of 682.
The next digit of our result is 8. 
Result so far: 75564.54838
Deduct 7688 from 8370 and we're left with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Going ahead to step 14:
961 can be fit into 6820 7 times, resulting in a remainder of 93.
Use 7 as the next digit of our solution. 
Result so far: 75564.548387
If we subtract 6727 from 6820, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 15:
The number 961 fits into 930 0 times, leaving a remainder of 930.
Record the quotient 0 as the next digit in the result. 
Result so far: 75564.548387
Subtracting 0 from 930 leaves us with 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9300, and continue the process.

Step 16:
961 goes into 9300 9 times with a remainder of 651.
The number 9 becomes the next digit in our result. 
Result so far: 75564.54838709
Subtracting 8649 from 9300 leaves us with 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

The final result is 75564.54838709 with a remainder of 6.51e-07.
