8915931 ÷ 641 
We want to figure out the number of times 8915931 can be divided by 641.

Advancing to step 1:
The number 641 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 641

Advancing to step 2:
The number 641 fits into 89 0 times, leaving a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Take the next digit (1) from the dividend and append it to 89, then repeat: 891 / 641

Step 3:
641 goes into 891 1 times with a remainder of 250.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 641 from 891 to get 250.
Grab the next digit (5) from the dividend, add it to 250, then carry on: 2505 / 641

Step 4:
641 goes into 2505 3 times with a remainder of 582.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 582 after subtracting 1923 from 2505.
Include the next digit (9) from the dividend after 582, then repeat: 5829 / 641

Moving on to step 5:
When dividing 5829 by 641, we get 9 with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Subtracting 5769 from 5829 leaves us with 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 641

Let's proceed to step 6:
603 divided by 641 is 0 with a remainder of 603.
Write down 0 as next digit of the result. 
Result so far: 1390.0
Subtract 0 from 603 to get 603.
Bring next digit (1) of the dividend behind the 603 and repeat the process: 6031 / 641

Advancing to step 7:
641 can be fit into 6031 9 times, resulting in a remainder of 262.
Use 9 as the next digit of our solution. 
Result so far: 13909.0
If we subtract 5769 from 6031, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 8:
641 goes into 2620 4 times with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 13909.4
If we take 2564 away from 2620, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
The number 641 fits into 560 0 times, leaving a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 13909.4
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 10:
641 goes into 5600 8 times with a remainder of 472.
Use 8 as the next digit of our solution. 
Result so far: 13909.408
If we subtract 5128 from 5600, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 11:
641 can be fit into 4720 7 times, resulting in a remainder of 233.
Use 7 as the next digit of our solution. 
Result so far: 13909.4087
Subtracting 4487 from 4720 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 12:
2330 divided by 641 is 3 with a remainder of 407.
Use 3 as the next digit of our solution. 
Result so far: 13909.40873
Deduct 1923 from 2330 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Moving on to step 13:
641 can be fit into 4070 6 times, resulting in a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 13909.408736
Subtracting 3846 from 4070 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 14:
641 goes into 2240 3 times with a remainder of 317.
Write down 3 as next digit of the result. 
Result so far: 13909.4087363
Subtract 1923 from 2240 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

On to step 15:
641 goes into 3170 4 times with a remainder of 606.
The number 4 becomes the next digit in our result. 
Result so far: 13909.40873634
If we take 2564 away from 3170, we end up with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Our division results in 13909.40873634 with a remaining 6.06e-07.
