We look at the division of 88758792 by 997 
The aim is to understand the frequency of 997 in 88758792.

Step 1:
The number 997 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 997

Step 2:
If we divide 88 by 997, we get 0 and a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Bring next digit (7) of the dividend behind the 88 and repeat the process: 887 / 997

On to step 3:
887 divided by 997 is 0 with a remainder of 887.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 887, we end up with 887.
Append the next digit (5) from the dividend to 887 and continue with: 8875 / 997

Step 4:
If we divide 8875 by 997, we get 8 and a remainder of 899.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 7976 from 8875 to get 899.
Include the next digit (8) from the dividend after 899, then repeat: 8998 / 997

Moving on to step 5:
The number 997 fits into 8998 9 times, leaving a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we take 8973 away from 8998, we end up with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 997

On to step 6:
257 divided by 997 is 0 with a remainder of 257.
The next digit of our result is 0. 
Result so far: 890.0
Subtract 0 from 257 to get 257.
Bring next digit (9) of the dividend behind the 257 and repeat the process: 2579 / 997

Step 7:
997 goes into 2579 2 times with a remainder of 585.
Use 2 as the next digit of our solution. 
Result so far: 8902.0
Deduct 1994 from 2579 and we're left with 585.
Include the next digit (2) from the dividend after 585, then repeat: 5852 / 997

Advancing to step 8:
997 can be fit into 5852 5 times, resulting in a remainder of 867.
Use 5 as the next digit of our solution. 
Result so far: 89025.0
Deduct 4985 from 5852 and we're left with 867.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8670, and continue the process.

Advancing to step 9:
8670 divided by 997 is 8 with a remainder of 694.
The number 8 becomes the next digit in our result. 
Result so far: 89025.8
The remainder is 694 after subtracting 7976 from 8670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Going ahead to step 10:
If we divide 6940 by 997, we get 6 and a remainder of 958.
Record the quotient 6 as the next digit in the result. 
Result so far: 89025.86
The remainder is 958 after subtracting 5982 from 6940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9580, and continue the process.

Moving on to step 11:
The number 997 fits into 9580 9 times, leaving a remainder of 607.
The next digit of our result is 9. 
Result so far: 89025.869
Subtracting 8973 from 9580 leaves us with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Advancing to step 12:
If we divide 6070 by 997, we get 6 and a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 89025.8696
If we take 5982 away from 6070, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 13:
If we divide 880 by 997, we get 0 and a remainder of 880.
Write down 0 as next digit of the result. 
Result so far: 89025.8696
The remainder is 880 after subtracting 0 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

On to step 14:
If we divide 8800 by 997, we get 8 and a remainder of 824.
Record the quotient 8 as the next digit in the result. 
Result so far: 89025.869608
The remainder is 824 after subtracting 7976 from 8800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Going ahead to step 15:
When dividing 8240 by 997, we get 8 with a remainder of 264.
Use 8 as the next digit of our solution. 
Result so far: 89025.8696088
The remainder is 264 after subtracting 7976 from 8240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

The final result is 89025.8696088 with a remainder of 2.64e-06.
