We look at the division of 253686 by 63 
We're looking to find how many times 63 goes into 253686.

Step 1:
63 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 63

Let's proceed to step 2:
The number 63 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 63

Let's proceed to step 3:
The number 63 fits into 253 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 252 from 253 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 63

Moving on to step 4:
63 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we take 0 away from 16, we end up with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 63

On to step 5:
If we divide 168 by 63, we get 2 and a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 402.0
Subtract 126 from 168 to get 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 63

Moving on to step 6:
When dividing 426 by 63, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 4026.0
Subtracting 378 from 426 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
If we divide 480 by 63, we get 7 and a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 4026.7
Subtract 441 from 480 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 8:
63 goes into 390 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 4026.76
Subtract 378 from 390 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
120 divided by 63 is 1 with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 4026.761
Subtract 63 from 120 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 10:
570 divided by 63 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 4026.7619
Deduct 567 from 570 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
63 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 4026.7619
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
63 can be fit into 300 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 4026.761904
Subtracting 252 from 300 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
When dividing 480 by 63, we get 7 with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 4026.7619047
Deduct 441 from 480 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 14:
When dividing 390 by 63, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 4026.76190476
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 4026.76190476 with a remaining 1.2e-08.
