10639871 divided by 204 
We want to divide 10639871 by 204.

Moving on to step 1:
The number 204 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 204

Let's proceed to step 2:
10 divided by 204 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 204

Going ahead to step 3:
204 goes into 106 0 times with a remainder of 106.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 106 to get 106.
Grab the next digit (3) from the dividend, add it to 106, then carry on: 1063 / 204

Moving on to step 4:
204 can be fit into 1063 5 times, resulting in a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 1020 from 1063, we get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 204

Advancing to step 5:
439 divided by 204 is 2 with a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Deduct 408 from 439 and we're left with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 204

On to step 6:
When dividing 318 by 204, we get 1 with a remainder of 114.
The next digit of our result is 1. 
Result so far: 521.0
The remainder is 114 after subtracting 204 from 318.
Include the next digit (7) from the dividend after 114, then repeat: 1147 / 204

Step 7:
204 goes into 1147 5 times with a remainder of 127.
Record the quotient 5 as the next digit in the result. 
Result so far: 5215.0
Subtracting 1020 from 1147 leaves us with 127.
Grab the next digit (1) from the dividend, add it to 127, then carry on: 1271 / 204

On to step 8:
204 goes into 1271 6 times with a remainder of 47.
The number 6 becomes the next digit in our result. 
Result so far: 52156.0
Subtract 1224 from 1271 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
When dividing 470 by 204, we get 2 with a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 52156.2
If we take 408 away from 470, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
When dividing 620 by 204, we get 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 52156.23
If we subtract 612 from 620, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
If we divide 80 by 204, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 52156.23
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
800 divided by 204 is 3 with a remainder of 188.
Use 3 as the next digit of our solution. 
Result so far: 52156.2303
Deduct 612 from 800 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 13:
When dividing 1880 by 204, we get 9 with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 52156.23039
If we subtract 1836 from 1880, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
204 goes into 440 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 52156.230392
If we subtract 408 from 440, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 15:
If we divide 320 by 204, we get 1 and a remainder of 116.
Write down 1 as next digit of the result. 
Result so far: 52156.2303921
The remainder is 116 after subtracting 204 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 16:
If we divide 1160 by 204, we get 5 and a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 52156.23039215
Subtract 1020 from 1160 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 52156.23039215 with a remaining 1.4e-07.
