We're dividing 89866598 by 111 
The aim is to understand the frequency of 111 in 89866598.

Let's proceed to step 1:
When dividing 8 by 111, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 111

Going ahead to step 2:
111 can be fit into 89 0 times, resulting in a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Grab the next digit (8) from the dividend, add it to 89, then carry on: 898 / 111

Step 3:
If we divide 898 by 111, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 888 from 898 to get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 111

Advancing to step 4:
111 goes into 106 0 times with a remainder of 106.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtracting 0 from 106 leaves us with 106.
Append the next digit (6) from the dividend to 106 and continue with: 1066 / 111

Going ahead to step 5:
111 goes into 1066 9 times with a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 809.0
If we subtract 999 from 1066, we get 67.
Include the next digit (5) from the dividend after 67, then repeat: 675 / 111

Advancing to step 6:
When dividing 675 by 111, we get 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 8096.0
If we subtract 666 from 675, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 111

Step 7:
111 goes into 99 0 times with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 80960.0
If we take 0 away from 99, we end up with 99.
Take the next digit (8) from the dividend and append it to 99, then repeat: 998 / 111

Moving on to step 8:
111 can be fit into 998 8 times, resulting in a remainder of 110.
Put 8 as the next digit of the answer. 
Result so far: 809608.0
Subtracting 888 from 998 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 9:
111 can be fit into 1100 9 times, resulting in a remainder of 101.
The number 9 becomes the next digit in our result. 
Result so far: 809608.9
Deduct 999 from 1100 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 10:
The number 111 fits into 1010 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 809608.99
The remainder is 11 after subtracting 999 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 809608.99 and a remainder of 0.011.
