We look at the division of 420572 by 63 
We want to figure out the number of times 420572 can be divided by 63.

Advancing to step 1:
63 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 63

Let's proceed to step 2:
63 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 63

Going ahead to step 3:
63 can be fit into 420 6 times, resulting in a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 378 from 420 to get 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 63

Advancing to step 4:
If we divide 425 by 63, we get 6 and a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtract 378 from 425 to get 47.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 63

On to step 5:
63 goes into 477 7 times with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 667.0
If we subtract 441 from 477, we get 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 63

On to step 6:
When dividing 362 by 63, we get 5 with a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 6675.0
Subtract 315 from 362 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
If we divide 470 by 63, we get 7 and a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 6675.7
If we subtract 441 from 470, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 8:
63 can be fit into 290 4 times, resulting in a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 6675.74
If we take 252 away from 290, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
If we divide 380 by 63, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 6675.746
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
If we divide 20 by 63, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6675.746
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
If we divide 200 by 63, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 6675.74603
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
110 divided by 63 is 1 with a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 6675.746031
Deduct 63 from 110 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 13:
470 divided by 63 is 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 6675.7460317
If we take 441 away from 470, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 14:
When dividing 290 by 63, we get 4 with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 6675.74603174
Deduct 252 from 290 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 6675.74603174 and a remainder of 3.8e-08.
