We're dividing 63336221 by 125 
The aim is to understand the frequency of 125 in 63336221.

Moving on to step 1:
125 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 125

On to step 2:
If we divide 63 by 125, we get 0 and a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Bring next digit (3) of the dividend behind the 63 and repeat the process: 633 / 125

Step 3:
If we divide 633 by 125, we get 5 and a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 8 after subtracting 625 from 633.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 125

Moving on to step 4:
If we divide 83 by 125, we get 0 and a remainder of 83.
The next digit of our result is 0. 
Result so far: 50.0
Subtract 0 from 83 to get 83.
Fetch the next digit (6) from the dividend, attach it to 83 and continue: 836 / 125

Moving on to step 5:
When dividing 836 by 125, we get 6 with a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 506.0
If we take 750 away from 836, we end up with 86.
Append the next digit (2) from the dividend to 86 and continue with: 862 / 125

Step 6:
When dividing 862 by 125, we get 6 with a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 5066.0
The remainder is 112 after subtracting 750 from 862.
Include the next digit (2) from the dividend after 112, then repeat: 1122 / 125

Advancing to step 7:
The number 125 fits into 1122 8 times, leaving a remainder of 122.
Record the quotient 8 as the next digit in the result. 
Result so far: 50668.0
Subtract 1000 from 1122 to get 122.
Bring next digit (1) of the dividend behind the 122 and repeat the process: 1221 / 125

Advancing to step 8:
If we divide 1221 by 125, we get 9 and a remainder of 96.
Record the quotient 9 as the next digit in the result. 
Result so far: 506689.0
The remainder is 96 after subtracting 1125 from 1221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 9:
125 goes into 960 7 times with a remainder of 85.
The number 7 becomes the next digit in our result. 
Result so far: 506689.7
Subtract 875 from 960 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 10:
When dividing 850 by 125, we get 6 with a remainder of 100.
The next digit of our result is 6. 
Result so far: 506689.76
If we take 750 away from 850, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
125 goes into 1000 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 506689.768
If we take 1000 away from 1000, we end up with 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 12:
If we divide 0 by 125, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 506689.768
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
The number 125 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 506689.768
If we subtract 0 from 0, we 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.

After the division, we end up with 506689.768 and a remainder of 0.0.
