We're dividing 87186433 by 111 
The aim is to understand the frequency of 111 in 87186433.

Let's proceed to step 1:
111 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 111

Going ahead to step 2:
111 can be fit into 87 0 times, resulting in a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Grab the next digit (1) from the dividend, add it to 87, then carry on: 871 / 111

Going ahead to step 3:
871 divided by 111 is 7 with a remainder of 94.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 777 from 871 and we're left with 94.
Bring next digit (8) of the dividend behind the 94 and repeat the process: 948 / 111

On to step 4:
The number 111 fits into 948 8 times, leaving a remainder of 60.
The next digit of our result is 8. 
Result so far: 78.0
If we subtract 888 from 948, we get 60.
Append the next digit (6) from the dividend to 60 and continue with: 606 / 111

On to step 5:
111 goes into 606 5 times with a remainder of 51.
The next digit of our result is 5. 
Result so far: 785.0
If we take 555 away from 606, we end up with 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 111

On to step 6:
111 can be fit into 514 4 times, resulting in a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 7854.0
Subtract 444 from 514 to get 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 111

Moving on to step 7:
703 divided by 111 is 6 with a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 78546.0
If we take 666 away from 703, we end up with 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 111

Step 8:
When dividing 373 by 111, we get 3 with a remainder of 40.
The next digit of our result is 3. 
Result so far: 785463.0
Deduct 333 from 373 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
When dividing 400 by 111, we get 3 with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 785463.3
Subtract 333 from 400 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 10:
The number 111 fits into 670 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 785463.36
The remainder is 4 after subtracting 666 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
When dividing 40 by 111, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 785463.36
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
111 can be fit into 400 3 times, resulting in a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 785463.3603
If we subtract 333 from 400, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 13:
670 divided by 111 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 785463.36036
Deduct 666 from 670 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
When dividing 40 by 111, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 785463.36036
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
400 divided by 111 is 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 785463.3603603
Subtracting 333 from 400 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 16:
111 can be fit into 670 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 785463.36036036
Deduct 666 from 670 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 785463.36036036, and the remainder is 4e-09.
