We look at the division of 615174 by 63 
The aim is to understand the frequency of 63 in 615174.

Moving on to step 1:
When dividing 6 by 63, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 63

Let's proceed to step 2:
63 goes into 61 0 times with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 63

Going ahead to step 3:
If we divide 615 by 63, we get 9 and a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 567 away from 615, we end up with 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 63

Moving on to step 4:
63 goes into 481 7 times with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 97.0
If we subtract 441 from 481, we get 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 63

Step 5:
63 can be fit into 407 6 times, resulting in a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 976.0
Deduct 378 from 407 and we're left with 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 63

Moving on to step 6:
When dividing 294 by 63, we get 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 9764.0
Subtract 252 from 294 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
The number 63 fits into 420 6 times, leaving a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 9764.6
If we subtract 378 from 420, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
The number 63 fits into 420 6 times, leaving a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 9764.66
Subtract 378 from 420 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 9764.66, with a leftover of 0.042.
