938407 ÷ 25 
The aim is to understand the frequency of 25 in 938407.

Moving on to step 1:
25 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 25

On to step 2:
When dividing 93 by 25, we get 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 75 from 93, we get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 25

Moving on to step 3:
188 divided by 25 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 37.0
The remainder is 13 after subtracting 175 from 188.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 25

Advancing to step 4:
25 goes into 134 5 times with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 375.0
The remainder is 9 after subtracting 125 from 134.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 25

Let's proceed to step 5:
When dividing 90 by 25, we get 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3753.0
If we subtract 75 from 90, we get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 25

Moving on to step 6:
157 divided by 25 is 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 37536.0
If we take 150 away from 157, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
25 can be fit into 70 2 times, resulting in a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 37536.2
The remainder is 20 after subtracting 50 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 25, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 37536.28
Deduct 200 from 200 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.

Step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 37536.28
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:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 37536.28
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.

The quotient of the division is 37536.28, and the remainder is 0.0.
