We're dividing 255917 by 63 
Let's see how many times 63 fits into 255917.

Advancing to step 1:
When dividing 2 by 63, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 63

Moving on to step 2:
63 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 63

Step 3:
255 divided by 63 is 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 3 after subtracting 252 from 255.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 63

Step 4:
63 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 63

Moving on to step 5:
63 goes into 391 6 times with a remainder of 13.
The next digit of our result is 6. 
Result so far: 406.0
The remainder is 13 after subtracting 378 from 391.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 63

Let's proceed to step 6:
When dividing 137 by 63, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 4062.0
If we take 126 away from 137, we end up with 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 7:
When dividing 110 by 63, we get 1 with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 4062.1
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.

Step 8:
If we divide 470 by 63, we get 7 and a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 4062.17
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.

Step 9:
63 goes into 290 4 times with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 4062.174
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.

Advancing to step 10:
63 goes into 380 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 4062.1746
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
20 divided by 63 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 4062.1746
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
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: 4062.174603
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
The number 63 fits into 110 1 times, leaving a remainder of 47.
The next digit of our result is 1. 
Result so far: 4062.1746031
If we take 63 away from 110, we end up 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 14:
When dividing 470 by 63, we get 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 4062.17460317
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.

The final outcome is 4062.17460317, with a leftover of 2.9e-08.
