We look at the division of 12750867 by 636 
We want to divide 12750867 by 636.

Let's proceed to step 1:
When dividing 1 by 636, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 636

Going ahead to step 2:
636 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 636

On to step 3:
636 can be fit into 127 0 times, resulting in a remainder of 127.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 127 leaves us with 127.
Grab the next digit (5) from the dividend, add it to 127, then carry on: 1275 / 636

Let's proceed to step 4:
If we divide 1275 by 636, we get 2 and a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1272 from 1275 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 636

Going ahead to step 5:
30 divided by 636 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 636

Let's proceed to step 6:
The number 636 fits into 308 0 times, leaving a remainder of 308.
The next digit of our result is 0. 
Result so far: 200.0
If we take 0 away from 308, we end up with 308.
Include the next digit (6) from the dividend after 308, then repeat: 3086 / 636

Going ahead to step 7:
3086 divided by 636 is 4 with a remainder of 542.
The next digit of our result is 4. 
Result so far: 2004.0
If we take 2544 away from 3086, we end up with 542.
Bring next digit (7) of the dividend behind the 542 and repeat the process: 5427 / 636

Step 8:
636 can be fit into 5427 8 times, resulting in a remainder of 339.
Put 8 as the next digit of the answer. 
Result so far: 20048.0
Subtracting 5088 from 5427 leaves us with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 9:
The number 636 fits into 3390 5 times, leaving a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 20048.5
The remainder is 210 after subtracting 3180 from 3390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
When dividing 2100 by 636, we get 3 with a remainder of 192.
Put 3 as the next digit of the answer. 
Result so far: 20048.53
Subtracting 1908 from 2100 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 11:
1920 divided by 636 is 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 20048.533
Deduct 1908 from 1920 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 20048.533, with a leftover of 0.0012.
