We look at the division of 370881 by 63 
The aim is to understand the frequency of 63 in 370881.

On to step 1:
63 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 63

On to step 2:
The number 63 fits into 37 0 times, leaving a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 63

Going ahead to step 3:
If we divide 370 by 63, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 315 from 370, we get 55.
Grab the next digit (8) from the dividend, add it to 55, then carry on: 558 / 63

Going ahead to step 4:
If we divide 558 by 63, we get 8 and a remainder of 54.
The next digit of our result is 8. 
Result so far: 58.0
If we take 504 away from 558, we end up with 54.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 63

Moving on to step 5:
63 goes into 548 8 times with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 588.0
Subtract 504 from 548 to get 44.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 63

On to step 6:
63 can be fit into 441 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 5887.0
Subtract 441 from 441 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
If we divide 0 by 63, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5887.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
63 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5887.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 5887.0, with a leftover of 0.0.
