124631 ÷ 20 
Let's see how many times 20 fits into 124631.

Step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 20

Let's proceed to step 2:
20 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 20

Moving on to step 3:
When dividing 124 by 20, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 120 from 124, we get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 20

Going ahead to step 4:
The number 20 fits into 46 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 62.0
Subtracting 40 from 46 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 20

Advancing to step 5:
If we divide 63 by 20, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 623.0
Deduct 60 from 63 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 20

On to step 6:
20 can be fit into 31 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 6231.0
Deduct 20 from 31 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
20 goes into 110 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 6231.5
Deduct 100 from 110 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6231.55
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 6231.55 and a remainder of 0.0.
