We're dividing 82787964 by 641 
We're looking to find how many times 641 goes into 82787964.

Moving on to step 1:
641 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 641

Going ahead to step 2:
When dividing 82 by 641, we get 0 with a remainder of 82.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Take the next digit (7) from the dividend and append it to 82, then repeat: 827 / 641

Step 3:
827 divided by 641 is 1 with a remainder of 186.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 641 away from 827, we end up with 186.
Append the next digit (8) from the dividend to 186 and continue with: 1868 / 641

Let's proceed to step 4:
The number 641 fits into 1868 2 times, leaving a remainder of 586.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1282 from 1868 and we're left with 586.
Append the next digit (7) from the dividend to 586 and continue with: 5867 / 641

Step 5:
When dividing 5867 by 641, we get 9 with a remainder of 98.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we take 5769 away from 5867, we end up with 98.
Include the next digit (9) from the dividend after 98, then repeat: 989 / 641

Moving on to step 6:
If we divide 989 by 641, we get 1 and a remainder of 348.
Put 1 as the next digit of the answer. 
Result so far: 1291.0
The remainder is 348 after subtracting 641 from 989.
Fetch the next digit (6) from the dividend, attach it to 348 and continue: 3486 / 641

Advancing to step 7:
If we divide 3486 by 641, we get 5 and a remainder of 281.
Record the quotient 5 as the next digit in the result. 
Result so far: 12915.0
Subtract 3205 from 3486 to get 281.
Fetch the next digit (4) from the dividend, attach it to 281 and continue: 2814 / 641

Going ahead to step 8:
641 can be fit into 2814 4 times, resulting in a remainder of 250.
Put 4 as the next digit of the answer. 
Result so far: 129154.0
The remainder is 250 after subtracting 2564 from 2814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 9:
641 can be fit into 2500 3 times, resulting in a remainder of 577.
Put 3 as the next digit of the answer. 
Result so far: 129154.3
If we subtract 1923 from 2500, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Advancing to step 10:
5770 divided by 641 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 129154.39
Subtract 5769 from 5770 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
If we divide 10 by 641, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 129154.39
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
100 divided by 641 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 129154.39
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 129154.39 with a remainder of 0.001.
