We look at the division of 42387855 by 63 
Our goal is to divide 42387855 by 63.

Let's proceed to step 1:
63 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 63

Going ahead to step 2:
63 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 63

On to step 3:
The number 63 fits into 423 6 times, leaving a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 378 from 423 leaves us with 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 63

On to step 4:
If we divide 458 by 63, we get 7 and a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtracting 441 from 458 leaves us with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 63

Moving on to step 5:
If we divide 177 by 63, we get 2 and a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 672.0
The remainder is 51 after subtracting 126 from 177.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 63

On to step 6:
63 can be fit into 518 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 6728.0
Deduct 504 from 518 and we're left with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 63

Advancing to step 7:
If we divide 145 by 63, we get 2 and a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 67282.0
Deduct 126 from 145 and we're left with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 63

Step 8:
195 divided by 63 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 672823.0
Deduct 189 from 195 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
If we divide 60 by 63, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 672823.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
600 divided by 63 is 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 672823.09
If we subtract 567 from 600, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 11:
63 can be fit into 330 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 672823.095
Deduct 315 from 330 and we're left 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.

Let's proceed to step 12:
63 goes into 150 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 672823.0952
Subtracting 126 from 150 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
When dividing 240 by 63, we get 3 with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 672823.09523
Subtract 189 from 240 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 14:
If we divide 510 by 63, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 672823.095238
Subtract 504 from 510 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 15:
60 divided by 63 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 672823.095238
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 16:
If we divide 600 by 63, we get 9 and a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 672823.09523809
If we subtract 567 from 600, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final result is 672823.09523809 with a remainder of 3.3e-08.
