87102080 ÷ 918 
The aim is to understand the frequency of 918 in 87102080.

Moving on to step 1:
918 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 918

On to step 2:
When dividing 87 by 918, we get 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Grab the next digit (1) from the dividend, add it to 87, then carry on: 871 / 918

Step 3:
871 divided by 918 is 0 with a remainder of 871.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 871, we end up with 871.
Include the next digit (0) from the dividend after 871, then repeat: 8710 / 918

Going ahead to step 4:
918 can be fit into 8710 9 times, resulting in a remainder of 448.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 8262 from 8710, we get 448.
Fetch the next digit (2) from the dividend, attach it to 448 and continue: 4482 / 918

Going ahead to step 5:
If we divide 4482 by 918, we get 4 and a remainder of 810.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Deduct 3672 from 4482 and we're left with 810.
Include the next digit (0) from the dividend after 810, then repeat: 8100 / 918

Going ahead to step 6:
8100 divided by 918 is 8 with a remainder of 756.
Use 8 as the next digit of our solution. 
Result so far: 948.0
Subtract 7344 from 8100 to get 756.
Grab the next digit (8) from the dividend, add it to 756, then carry on: 7568 / 918

On to step 7:
When dividing 7568 by 918, we get 8 with a remainder of 224.
The next digit of our result is 8. 
Result so far: 9488.0
If we subtract 7344 from 7568, we get 224.
Include the next digit (0) from the dividend after 224, then repeat: 2240 / 918

Going ahead to step 8:
918 can be fit into 2240 2 times, resulting in a remainder of 404.
Record the quotient 2 as the next digit in the result. 
Result so far: 94882.0
Subtract 1836 from 2240 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 9:
The number 918 fits into 4040 4 times, leaving a remainder of 368.
Write down 4 as next digit of the result. 
Result so far: 94882.4
The remainder is 368 after subtracting 3672 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 10:
When dividing 3680 by 918, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 94882.44
Subtract 3672 from 3680 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 94882.44 with a remainder of 0.008.
