We look at the division of 8341808 by 641 
We want to figure out the number of times 8341808 can be divided by 641.

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
If we subtract 0 from 8, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 641

Advancing to step 2:
641 can be fit into 83 0 times, resulting in a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Include the next digit (4) from the dividend after 83, then repeat: 834 / 641

On to step 3:
834 divided by 641 is 1 with a remainder of 193.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 641 from 834 leaves us with 193.
Fetch the next digit (1) from the dividend, attach it to 193 and continue: 1931 / 641

Step 4:
1931 divided by 641 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 1923 from 1931 and we're left with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 641

Going ahead to step 5:
641 goes into 88 0 times with a remainder of 88.
The next digit of our result is 0. 
Result so far: 130.0
Subtracting 0 from 88 leaves us with 88.
Take the next digit (0) from the dividend and append it to 88, then repeat: 880 / 641

On to step 6:
If we divide 880 by 641, we get 1 and a remainder of 239.
Use 1 as the next digit of our solution. 
Result so far: 1301.0
If we take 641 away from 880, we end up with 239.
Include the next digit (8) from the dividend after 239, then repeat: 2398 / 641

On to step 7:
If we divide 2398 by 641, we get 3 and a remainder of 475.
Write down 3 as next digit of the result. 
Result so far: 13013.0
Subtracting 1923 from 2398 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 8:
641 goes into 4750 7 times with a remainder of 263.
Write down 7 as next digit of the result. 
Result so far: 13013.7
The remainder is 263 after subtracting 4487 from 4750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 9:
If we divide 2630 by 641, we get 4 and a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 13013.74
Deduct 2564 from 2630 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
660 divided by 641 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 13013.741
Subtracting 641 from 660 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
190 divided by 641 is 0 with a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 13013.741
If we take 0 away from 190, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 12:
The number 641 fits into 1900 2 times, leaving a remainder of 618.
The next digit of our result is 2. 
Result so far: 13013.74102
If we take 1282 away from 1900, we end up with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

On to step 13:
641 goes into 6180 9 times with a remainder of 411.
Write down 9 as next digit of the result. 
Result so far: 13013.741029
Subtract 5769 from 6180 to get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

On to step 14:
If we divide 4110 by 641, we get 6 and a remainder of 264.
Use 6 as the next digit of our solution. 
Result so far: 13013.7410296
If we take 3846 away from 4110, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 15:
If we divide 2640 by 641, we get 4 and a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 13013.74102964
If we subtract 2564 from 2640, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 13013.74102964 with a remaining 7.6e-08.
