We divide 133112 by 25
The aim is to understand the frequency of 25 in 133112.

Step 1:
If we divide 1 by 25, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 25

Step 2:
When dividing 13 by 25, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 25

Moving on to step 3:
If we divide 133 by 25, we get 5 and a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 125 away from 133, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 25

Moving on to step 4:
The number 25 fits into 81 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtract 75 from 81 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 25

Step 5:
The number 25 fits into 61 2 times, leaving a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 532.0
If we subtract 50 from 61, we get 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 25

Moving on to step 6:
The number 25 fits into 112 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 5324.0
If we take 100 away from 112, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
25 can be fit into 120 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 5324.4
Subtracting 100 from 120 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
25 goes into 200 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 5324.48
The remainder is 0 after subtracting 200 from 200.
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 9:
0 divided by 25 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5324.48
Deduct 0 from 0 and we're left 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 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5324.48
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 5324.48 and a remainder of 0.0.
