We look at the division of 12930115 by 641 
We're looking to find how many times 641 goes into 12930115.

Advancing to step 1:
When dividing 1 by 641, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 641

Going ahead to step 2:
641 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 641

Step 3:
When dividing 129 by 641, we get 0 with a remainder of 129.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 129 leaves us with 129.
Include the next digit (3) from the dividend after 129, then repeat: 1293 / 641

Advancing to step 4:
If we divide 1293 by 641, we get 2 and a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1282 from 1293, we get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 641

On to step 5:
The number 641 fits into 110 0 times, leaving a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 110 after subtracting 0 from 110.
Take the next digit (1) from the dividend and append it to 110, then repeat: 1101 / 641

On to step 6:
When dividing 1101 by 641, we get 1 with a remainder of 460.
The number 1 becomes the next digit in our result. 
Result so far: 201.0
The remainder is 460 after subtracting 641 from 1101.
Grab the next digit (1) from the dividend, add it to 460, then carry on: 4601 / 641

On to step 7:
641 can be fit into 4601 7 times, resulting in a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 2017.0
Deduct 4487 from 4601 and we're left with 114.
Bring next digit (5) of the dividend behind the 114 and repeat the process: 1145 / 641

Going ahead to step 8:
641 can be fit into 1145 1 times, resulting in a remainder of 504.
The next digit of our result is 1. 
Result so far: 20171.0
If we take 641 away from 1145, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 9:
5040 divided by 641 is 7 with a remainder of 553.
Write down 7 as next digit of the result. 
Result so far: 20171.7
Deduct 4487 from 5040 and we're left with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Advancing to step 10:
641 goes into 5530 8 times with a remainder of 402.
The number 8 becomes the next digit in our result. 
Result so far: 20171.78
If we subtract 5128 from 5530, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 11:
641 can be fit into 4020 6 times, resulting in a remainder of 174.
Write down 6 as next digit of the result. 
Result so far: 20171.786
If we subtract 3846 from 4020, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 12:
If we divide 1740 by 641, we get 2 and a remainder of 458.
The next digit of our result is 2. 
Result so far: 20171.7862
If we take 1282 away from 1740, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Going ahead to step 13:
4580 divided by 641 is 7 with a remainder of 93.
The number 7 becomes the next digit in our result. 
Result so far: 20171.78627
Subtracting 4487 from 4580 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 14:
If we divide 930 by 641, we get 1 and a remainder of 289.
Use 1 as the next digit of our solution. 
Result so far: 20171.786271
If we take 641 away from 930, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 15:
The number 641 fits into 2890 4 times, leaving a remainder of 326.
Put 4 as the next digit of the answer. 
Result so far: 20171.7862714
If we take 2564 away from 2890, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 16:
641 can be fit into 3260 5 times, resulting in a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 20171.78627145
Deduct 3205 from 3260 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 20171.78627145 with a remaining 5.5e-08.
