Let's divide 19996571 by 124
Our goal is to divide 19996571 by 124.

Going ahead to step 1:
The number 124 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
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 124

Moving on to step 2:
19 divided by 124 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 124

On to step 3:
199 divided by 124 is 1 with a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 124 away from 199, we end up with 75.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 124

Advancing to step 4:
When dividing 759 by 124, we get 6 with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 15 after subtracting 744 from 759.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 124

Step 5:
When dividing 156 by 124, we get 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 161.0
Subtracting 124 from 156 leaves us with 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 124

Step 6:
When dividing 325 by 124, we get 2 with a remainder of 77.
The number 2 becomes the next digit in our result. 
Result so far: 1612.0
The remainder is 77 after subtracting 248 from 325.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 124

Going ahead to step 7:
When dividing 777 by 124, we get 6 with a remainder of 33.
The next digit of our result is 6. 
Result so far: 16126.0
Subtracting 744 from 777 leaves us with 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 124

On to step 8:
The number 124 fits into 331 2 times, leaving a remainder of 83.
Record the quotient 2 as the next digit in the result. 
Result so far: 161262.0
If we subtract 248 from 331, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
The number 124 fits into 830 6 times, leaving a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 161262.6
The remainder is 86 after subtracting 744 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 10:
The number 124 fits into 860 6 times, leaving a remainder of 116.
Write down 6 as next digit of the result. 
Result so far: 161262.66
Subtract 744 from 860 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

After the division, we end up with 161262.66 and a remainder of 0.116.
