We divide 86187985 by 111
The aim is to understand the frequency of 111 in 86187985.

Advancing to step 1:
8 divided by 111 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 111

Advancing to step 2:
The number 111 fits into 86 0 times, leaving a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 111

Step 3:
111 goes into 861 7 times with a remainder of 84.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 777 from 861 and we're left with 84.
Include the next digit (8) from the dividend after 84, then repeat: 848 / 111

Advancing to step 4:
111 can be fit into 848 7 times, resulting in a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtract 777 from 848 to get 71.
Grab the next digit (7) from the dividend, add it to 71, then carry on: 717 / 111

Moving on to step 5:
The number 111 fits into 717 6 times, leaving a remainder of 51.
The number 6 becomes the next digit in our result. 
Result so far: 776.0
Subtract 666 from 717 to get 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 111

On to step 6:
When dividing 519 by 111, we get 4 with a remainder of 75.
Use 4 as the next digit of our solution. 
Result so far: 7764.0
Subtract 444 from 519 to get 75.
Take the next digit (8) from the dividend and append it to 75, then repeat: 758 / 111

On to step 7:
758 divided by 111 is 6 with a remainder of 92.
The next digit of our result is 6. 
Result so far: 77646.0
The remainder is 92 after subtracting 666 from 758.
Grab the next digit (5) from the dividend, add it to 92, then carry on: 925 / 111

Step 8:
111 goes into 925 8 times with a remainder of 37.
The next digit of our result is 8. 
Result so far: 776468.0
Deduct 888 from 925 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
The number 111 fits into 370 3 times, leaving a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 776468.3
If we subtract 333 from 370, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 10:
The number 111 fits into 370 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 776468.33
Deduct 333 from 370 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The quotient of the division is 776468.33, and the remainder is 0.037.
