We look at the division of 63146590 by 915 
We want to divide 63146590 by 915.

Moving on to step 1:
The number 915 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 915

Advancing to step 2:
When dividing 63 by 915, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 915

Advancing to step 3:
631 divided by 915 is 0 with a remainder of 631.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 631 leaves us with 631.
Bring next digit (4) of the dividend behind the 631 and repeat the process: 6314 / 915

Step 4:
915 can be fit into 6314 6 times, resulting in a remainder of 824.
The next digit of our result is 6. 
Result so far: 6.0
If we take 5490 away from 6314, we end up with 824.
Append the next digit (6) from the dividend to 824 and continue with: 8246 / 915

Advancing to step 5:
If we divide 8246 by 915, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we take 8235 away from 8246, we end up with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 915

Step 6:
915 can be fit into 115 0 times, resulting in a remainder of 115.
The number 0 becomes the next digit in our result. 
Result so far: 690.0
The remainder is 115 after subtracting 0 from 115.
Bring next digit (9) of the dividend behind the 115 and repeat the process: 1159 / 915

Going ahead to step 7:
915 goes into 1159 1 times with a remainder of 244.
The next digit of our result is 1. 
Result so far: 6901.0
Deduct 915 from 1159 and we're left with 244.
Bring next digit (0) of the dividend behind the 244 and repeat the process: 2440 / 915

Going ahead to step 8:
2440 divided by 915 is 2 with a remainder of 610.
Write down 2 as next digit of the result. 
Result so far: 69012.0
Subtract 1830 from 2440 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 9:
6100 divided by 915 is 6 with a remainder of 610.
Record the quotient 6 as the next digit in the result. 
Result so far: 69012.6
The remainder is 610 after subtracting 5490 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 10:
915 goes into 6100 6 times with a remainder of 610.
Write down 6 as next digit of the result. 
Result so far: 69012.66
Subtracting 5490 from 6100 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

The final result is 69012.66 with a remainder of 0.61.
