We look at the division of 90944 by 25 
The aim is to understand the frequency of 25 in 90944.

Step 1:
25 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 25

Advancing to step 2:
The number 25 fits into 90 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 75 from 90 and we're left with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 25

Going ahead to step 3:
25 can be fit into 159 6 times, resulting in a remainder of 9.
The next digit of our result is 6. 
Result so far: 36.0
Deduct 150 from 159 and we're left with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 25

Step 4:
25 can be fit into 94 3 times, resulting in a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 363.0
If we take 75 away from 94, we end up with 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 25

Going ahead to step 5:
194 divided by 25 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 3637.0
The remainder is 19 after subtracting 175 from 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 6:
190 divided by 25 is 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 3637.7
Deduct 175 from 190 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
150 divided by 25 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 3637.76
Deduct 150 from 150 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.

On to step 8:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3637.76
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.

Let's proceed to step 9:
0 divided by 25 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3637.76
Subtract 0 from 0 to 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.

Our division results in 3637.76 with a remaining 0.0.
