We're dividing 725522 by 63 
The aim is to understand the frequency of 63 in 725522.

Advancing to step 1:
The number 63 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 63

Advancing to step 2:
If we divide 72 by 63, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 63 from 72 and we're left with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 63

Step 3:
63 goes into 95 1 times with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 63 from 95 and we're left with 32.
Include the next digit (5) from the dividend after 32, then repeat: 325 / 63

Going ahead to step 4:
If we divide 325 by 63, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Deduct 315 from 325 and we're left with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 63

On to step 5:
If we divide 102 by 63, we get 1 and a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1151.0
Deduct 63 from 102 and we're left with 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 63

Let's proceed to step 6:
The number 63 fits into 392 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 11516.0
If we subtract 378 from 392, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
63 can be fit into 140 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 11516.2
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
63 goes into 140 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 11516.22
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 11516.22 and a remainder of 0.014.
