82761057 ÷ 641 
Our goal is to divide 82761057 by 641.

Advancing to step 1:
8 divided by 641 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 641

Step 2:
If we divide 82 by 641, we get 0 and a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Grab the next digit (7) from the dividend, add it to 82, then carry on: 827 / 641

Going ahead to step 3:
827 divided by 641 is 1 with a remainder of 186.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 186 after subtracting 641 from 827.
Grab the next digit (6) from the dividend, add it to 186, then carry on: 1866 / 641

Moving on to step 4:
641 goes into 1866 2 times with a remainder of 584.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1282 from 1866 and we're left with 584.
Take the next digit (1) from the dividend and append it to 584, then repeat: 5841 / 641

On to step 5:
If we divide 5841 by 641, we get 9 and a remainder of 72.
Write down 9 as next digit of the result. 
Result so far: 129.0
If we subtract 5769 from 5841, we get 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 641

Moving on to step 6:
The number 641 fits into 720 1 times, leaving a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 1291.0
Subtract 641 from 720 to get 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 641

Moving on to step 7:
641 goes into 795 1 times with a remainder of 154.
Record the quotient 1 as the next digit in the result. 
Result so far: 12911.0
If we take 641 away from 795, we end up with 154.
Bring next digit (7) of the dividend behind the 154 and repeat the process: 1547 / 641

On to step 8:
When dividing 1547 by 641, we get 2 with a remainder of 265.
Write down 2 as next digit of the result. 
Result so far: 129112.0
If we subtract 1282 from 1547, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 9:
641 goes into 2650 4 times with a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 129112.4
If we take 2564 away from 2650, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 10:
The number 641 fits into 860 1 times, leaving a remainder of 219.
The next digit of our result is 1. 
Result so far: 129112.41
The remainder is 219 after subtracting 641 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 11:
641 goes into 2190 3 times with a remainder of 267.
Write down 3 as next digit of the result. 
Result so far: 129112.413
If we take 1923 away from 2190, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Let's proceed to step 12:
If we divide 2670 by 641, we get 4 and a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 129112.4134
The remainder is 106 after subtracting 2564 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 13:
If we divide 1060 by 641, we get 1 and a remainder of 419.
The number 1 becomes the next digit in our result. 
Result so far: 129112.41341
Deduct 641 from 1060 and we're left with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Let's proceed to step 14:
If we divide 4190 by 641, we get 6 and a remainder of 344.
The next digit of our result is 6. 
Result so far: 129112.413416
Subtract 3846 from 4190 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 15:
The number 641 fits into 3440 5 times, leaving a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 129112.4134165
If we subtract 3205 from 3440, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 16:
The number 641 fits into 2350 3 times, leaving a remainder of 427.
The number 3 becomes the next digit in our result. 
Result so far: 129112.41341653
Deduct 1923 from 2350 and we're left with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

The final outcome is 129112.41341653, with a leftover of 4.27e-07.
