Let's divide 126355 by 20
We want to divide 126355 by 20.

Going ahead to step 1:
20 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in 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 / 20

Advancing to step 2:
20 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 20

Step 3:
20 goes into 126 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 120 from 126 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 20

Step 4:
The number 20 fits into 63 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
If we subtract 60 from 63, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 20

Let's proceed to step 5:
20 can be fit into 35 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 631.0
If we take 20 away from 35, we end up with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 20

Step 6:
20 goes into 155 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 6317.0
If we take 140 away from 155, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
If we divide 150 by 20, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 6317.7
If we subtract 140 from 150, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 20 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 6317.75
Subtract 100 from 100 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6317.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6317.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 6317.75, and the remainder is 0.0.
