We look at the division of 84288912 by 988 
The aim is to understand the frequency of 988 in 84288912.

Going ahead to step 1:
If we divide 8 by 988, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 988

Let's proceed to step 2:
988 can be fit into 84 0 times, resulting in a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Take the next digit (2) from the dividend and append it to 84, then repeat: 842 / 988

Going ahead to step 3:
When dividing 842 by 988, we get 0 with a remainder of 842.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 842, we get 842.
Append the next digit (8) from the dividend to 842 and continue with: 8428 / 988

Advancing to step 4:
The number 988 fits into 8428 8 times, leaving a remainder of 524.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 524 after subtracting 7904 from 8428.
Include the next digit (8) from the dividend after 524, then repeat: 5248 / 988

Step 5:
If we divide 5248 by 988, we get 5 and a remainder of 308.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
The remainder is 308 after subtracting 4940 from 5248.
Append the next digit (9) from the dividend to 308 and continue with: 3089 / 988

On to step 6:
3089 divided by 988 is 3 with a remainder of 125.
The number 3 becomes the next digit in our result. 
Result so far: 853.0
The remainder is 125 after subtracting 2964 from 3089.
Take the next digit (1) from the dividend and append it to 125, then repeat: 1251 / 988

Advancing to step 7:
988 can be fit into 1251 1 times, resulting in a remainder of 263.
Put 1 as the next digit of the answer. 
Result so far: 8531.0
Deduct 988 from 1251 and we're left with 263.
Include the next digit (2) from the dividend after 263, then repeat: 2632 / 988

On to step 8:
The number 988 fits into 2632 2 times, leaving a remainder of 656.
Put 2 as the next digit of the answer. 
Result so far: 85312.0
The remainder is 656 after subtracting 1976 from 2632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Step 9:
988 can be fit into 6560 6 times, resulting in a remainder of 632.
The number 6 becomes the next digit in our result. 
Result so far: 85312.6
Subtracting 5928 from 6560 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 10:
If we divide 6320 by 988, we get 6 and a remainder of 392.
The number 6 becomes the next digit in our result. 
Result so far: 85312.66
Deduct 5928 from 6320 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

After the division, we end up with 85312.66 and a remainder of 0.392.
