We look at the division of 77982783 by 961 
We're looking to find how many times 961 goes into 77982783.

Step 1:
The number 961 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 961

Moving on to step 2:
961 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 961

Advancing to step 3:
779 divided by 961 is 0 with a remainder of 779.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 779, we get 779.
Grab the next digit (8) from the dividend, add it to 779, then carry on: 7798 / 961

Step 4:
961 goes into 7798 8 times with a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 7688 from 7798 and we're left with 110.
Grab the next digit (2) from the dividend, add it to 110, then carry on: 1102 / 961

Step 5:
1102 divided by 961 is 1 with a remainder of 141.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtract 961 from 1102 to get 141.
Grab the next digit (7) from the dividend, add it to 141, then carry on: 1417 / 961

Advancing to step 6:
The number 961 fits into 1417 1 times, leaving a remainder of 456.
The number 1 becomes the next digit in our result. 
Result so far: 811.0
The remainder is 456 after subtracting 961 from 1417.
Append the next digit (8) from the dividend to 456 and continue with: 4568 / 961

Let's proceed to step 7:
4568 divided by 961 is 4 with a remainder of 724.
Write down 4 as next digit of the result. 
Result so far: 8114.0
Deduct 3844 from 4568 and we're left with 724.
Include the next digit (3) from the dividend after 724, then repeat: 7243 / 961

On to step 8:
961 goes into 7243 7 times with a remainder of 516.
Use 7 as the next digit of our solution. 
Result so far: 81147.0
If we take 6727 away from 7243, we end up with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 9:
961 goes into 5160 5 times with a remainder of 355.
The next digit of our result is 5. 
Result so far: 81147.5
The remainder is 355 after subtracting 4805 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 10:
961 can be fit into 3550 3 times, resulting in a remainder of 667.
Write down 3 as next digit of the result. 
Result so far: 81147.53
Subtract 2883 from 3550 to get 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

On to step 11:
961 can be fit into 6670 6 times, resulting in a remainder of 904.
Write down 6 as next digit of the result. 
Result so far: 81147.536
If we subtract 5766 from 6670, we get 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

Let's proceed to step 12:
961 can be fit into 9040 9 times, resulting in a remainder of 391.
Write down 9 as next digit of the result. 
Result so far: 81147.5369
If we subtract 8649 from 9040, we get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

On to step 13:
The number 961 fits into 3910 4 times, leaving a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 81147.53694
Subtract 3844 from 3910 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 14:
If we divide 660 by 961, we get 0 and a remainder of 660.
Record the quotient 0 as the next digit in the result. 
Result so far: 81147.53694
The remainder is 660 after subtracting 0 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 15:
If we divide 6600 by 961, we get 6 and a remainder of 834.
Record the quotient 6 as the next digit in the result. 
Result so far: 81147.5369406
If we take 5766 away from 6600, we end up with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Let's proceed to step 16:
If we divide 8340 by 961, we get 8 and a remainder of 652.
Use 8 as the next digit of our solution. 
Result so far: 81147.53694068
The remainder is 652 after subtracting 7688 from 8340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

The final outcome is 81147.53694068, with a leftover of 6.52e-07.
