Let's divide 1222525 by 125
The aim is to understand the frequency of 125 in 1222525.

On to step 1:
1 divided by 125 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 125

Going ahead to step 2:
125 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 125

Let's proceed to step 3:
If we divide 122 by 125, we get 0 and a remainder of 122.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 122 leaves us with 122.
Take the next digit (2) from the dividend and append it to 122, then repeat: 1222 / 125

Moving on to step 4:
125 goes into 1222 9 times with a remainder of 97.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 1125 from 1222 and we're left with 97.
Bring next digit (5) of the dividend behind the 97 and repeat the process: 975 / 125

Advancing to step 5:
975 divided by 125 is 7 with a remainder of 100.
Write down 7 as next digit of the result. 
Result so far: 97.0
If we take 875 away from 975, we end up with 100.
Append the next digit (2) from the dividend to 100 and continue with: 1002 / 125

On to step 6:
125 can be fit into 1002 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 978.0
The remainder is 2 after subtracting 1000 from 1002.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 125

On to step 7:
25 divided by 125 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 9780.0
Subtracting 0 from 25 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
125 goes into 250 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 9780.2
The remainder is 0 after subtracting 250 from 250.
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 9:
125 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9780.2
If we take 0 away from 0, 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.

Step 10:
125 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 9780.2
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.

After the division, we end up with 9780.2 and a remainder of 0.0.
