We're dividing 974143 by 25 
The aim is to understand the frequency of 25 in 974143.

Going ahead to 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
Subtracting 0 from 9 leaves us with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 25

Advancing to step 2:
97 divided by 25 is 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 22 after subtracting 75 from 97.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 25

Moving on to step 3:
25 can be fit into 224 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we take 200 away from 224, we end up with 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 25

Moving on to step 4:
241 divided by 25 is 9 with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 389.0
Subtract 225 from 241 to get 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 25

Step 5:
If we divide 164 by 25, we get 6 and a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 3896.0
Subtracting 150 from 164 leaves us with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 25

Step 6:
143 divided by 25 is 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 38965.0
Deduct 125 from 143 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
The number 25 fits into 180 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 38965.7
If we take 175 away from 180, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
The number 25 fits into 50 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 38965.72
If we subtract 50 from 50, 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.

Moving on to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 38965.72
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.

Moving on to step 10:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 38965.72
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.

The final result is 38965.72 with a remainder of 0.0.
