Let's divide 36661807 by 111
The aim is to understand the frequency of 111 in 36661807.

On to step 1:
3 divided by 111 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 111

Step 2:
If we divide 36 by 111, we get 0 and a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 111

Going ahead to step 3:
When dividing 366 by 111, we get 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 33 after subtracting 333 from 366.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 111

Advancing to step 4:
336 divided by 111 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we subtract 333 from 336, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 111

Moving on to step 5:
If we divide 31 by 111, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 330.0
If we subtract 0 from 31, we get 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 111

Going ahead to step 6:
If we divide 318 by 111, we get 2 and a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 3302.0
Deduct 222 from 318 and we're left with 96.
Include the next digit (0) from the dividend after 96, then repeat: 960 / 111

On to step 7:
960 divided by 111 is 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 33028.0
If we take 888 away from 960, we end up with 72.
Append the next digit (7) from the dividend to 72 and continue with: 727 / 111

Let's proceed to step 8:
The number 111 fits into 727 6 times, leaving a remainder of 61.
The number 6 becomes the next digit in our result. 
Result so far: 330286.0
If we subtract 666 from 727, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
When dividing 610 by 111, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 330286.5
Deduct 555 from 610 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
550 divided by 111 is 4 with a remainder of 106.
Use 4 as the next digit of our solution. 
Result so far: 330286.54
The remainder is 106 after subtracting 444 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 11:
The number 111 fits into 1060 9 times, leaving a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 330286.549
Deduct 999 from 1060 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
The number 111 fits into 610 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 330286.5495
Subtract 555 from 610 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 13:
111 can be fit into 550 4 times, resulting in a remainder of 106.
Use 4 as the next digit of our solution. 
Result so far: 330286.54954
Subtracting 444 from 550 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 14:
When dividing 1060 by 111, we get 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 330286.549549
Deduct 999 from 1060 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 15:
The number 111 fits into 610 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 330286.5495495
If we take 555 away from 610, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 16:
If we divide 550 by 111, we get 4 and a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 330286.54954954
If we take 444 away from 550, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Our division results in 330286.54954954 with a remaining 1.06e-07.
