We're dividing 12980143 by 625 
Our goal is to divide 12980143 by 625.

Step 1:
The number 625 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 625

Moving on to step 2:
When dividing 12 by 625, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 625

Going ahead to step 3:
625 can be fit into 129 0 times, resulting in a remainder of 129.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 129, we get 129.
Include the next digit (8) from the dividend after 129, then repeat: 1298 / 625

On to step 4:
625 can be fit into 1298 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1250 from 1298 to get 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 625

Let's proceed to step 5:
625 goes into 480 0 times with a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 480, we end up with 480.
Bring next digit (1) of the dividend behind the 480 and repeat the process: 4801 / 625

Moving on to step 6:
625 can be fit into 4801 7 times, resulting in a remainder of 426.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
If we take 4375 away from 4801, we end up with 426.
Fetch the next digit (4) from the dividend, attach it to 426 and continue: 4264 / 625

Advancing to step 7:
If we divide 4264 by 625, we get 6 and a remainder of 514.
Put 6 as the next digit of the answer. 
Result so far: 2076.0
The remainder is 514 after subtracting 3750 from 4264.
Append the next digit (3) from the dividend to 514 and continue with: 5143 / 625

Going ahead to step 8:
When dividing 5143 by 625, we get 8 with a remainder of 143.
The next digit of our result is 8. 
Result so far: 20768.0
Deduct 5000 from 5143 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 9:
When dividing 1430 by 625, we get 2 with a remainder of 180.
The next digit of our result is 2. 
Result so far: 20768.2
Subtract 1250 from 1430 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 10:
When dividing 1800 by 625, we get 2 with a remainder of 550.
Write down 2 as next digit of the result. 
Result so far: 20768.22
Deduct 1250 from 1800 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

After the division, we end up with 20768.22 and a remainder of 0.55.
