We're dividing 127421 by 63 
Our goal is to divide 127421 by 63.

On to step 1:
1 divided by 63 is 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.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 63

Moving on to step 2:
The number 63 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 63

Moving on to step 3:
If we divide 127 by 63, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 126 away from 127, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 63

On to step 4:
14 divided by 63 is 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 63

Moving on to step 5:
63 goes into 142 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 202.0
If we take 126 away from 142, we end up with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 63

Moving on to step 6:
When dividing 161 by 63, we get 2 with a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 2022.0
Deduct 126 from 161 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
When dividing 350 by 63, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 2022.5
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
350 divided by 63 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 2022.55
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 2022.55, with a leftover of 0.035.
