We're dividing 87116530 by 988 
The aim is to understand the frequency of 988 in 87116530.

Step 1:
988 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 988

Advancing to step 2:
If we divide 87 by 988, we get 0 and a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Append the next digit (1) from the dividend to 87 and continue with: 871 / 988

Going ahead to step 3:
When dividing 871 by 988, we get 0 with a remainder of 871.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 871 to get 871.
Grab the next digit (1) from the dividend, add it to 871, then carry on: 8711 / 988

Going ahead to step 4:
8711 divided by 988 is 8 with a remainder of 807.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 7904 from 8711 leaves us with 807.
Take the next digit (6) from the dividend and append it to 807, then repeat: 8076 / 988

Advancing to step 5:
The number 988 fits into 8076 8 times, leaving a remainder of 172.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtract 7904 from 8076 to get 172.
Grab the next digit (5) from the dividend, add it to 172, then carry on: 1725 / 988

Moving on to step 6:
988 can be fit into 1725 1 times, resulting in a remainder of 737.
Record the quotient 1 as the next digit in the result. 
Result so far: 881.0
Subtracting 988 from 1725 leaves us with 737.
Bring next digit (3) of the dividend behind the 737 and repeat the process: 7373 / 988

Moving on to step 7:
The number 988 fits into 7373 7 times, leaving a remainder of 457.
The next digit of our result is 7. 
Result so far: 8817.0
Subtracting 6916 from 7373 leaves us with 457.
Include the next digit (0) from the dividend after 457, then repeat: 4570 / 988

Advancing to step 8:
The number 988 fits into 4570 4 times, leaving a remainder of 618.
Use 4 as the next digit of our solution. 
Result so far: 88174.0
Subtracting 3952 from 4570 leaves us with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Step 9:
988 goes into 6180 6 times with a remainder of 252.
Put 6 as the next digit of the answer. 
Result so far: 88174.6
Subtracting 5928 from 6180 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 10:
If we divide 2520 by 988, we get 2 and a remainder of 544.
The number 2 becomes the next digit in our result. 
Result so far: 88174.62
Subtracting 1976 from 2520 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 11:
988 can be fit into 5440 5 times, resulting in a remainder of 500.
The next digit of our result is 5. 
Result so far: 88174.625
Subtracting 4940 from 5440 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 12:
988 can be fit into 5000 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 88174.6255
If we take 4940 away from 5000, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 88174.6255 with a remaining 0.0006.
