20015186 ÷ 118 
The aim is to understand the frequency of 118 in 20015186.

Moving on to step 1:
2 divided by 118 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 118

Step 2:
20 divided by 118 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 118

Let's proceed to step 3:
200 divided by 118 is 1 with a remainder of 82.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 118 from 200, we get 82.
Bring next digit (1) of the dividend behind the 82 and repeat the process: 821 / 118

Step 4:
When dividing 821 by 118, we get 6 with a remainder of 113.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 708 from 821 to get 113.
Fetch the next digit (5) from the dividend, attach it to 113 and continue: 1135 / 118

Going ahead to step 5:
118 goes into 1135 9 times with a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 169.0
Subtract 1062 from 1135 to get 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 118

Step 6:
731 divided by 118 is 6 with a remainder of 23.
The next digit of our result is 6. 
Result so far: 1696.0
The remainder is 23 after subtracting 708 from 731.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 118

On to step 7:
When dividing 238 by 118, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 16962.0
Deduct 236 from 238 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 118

Moving on to step 8:
118 goes into 26 0 times with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 169620.0
Subtract 0 from 26 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
When dividing 260 by 118, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 169620.2
Subtracting 236 from 260 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
118 goes into 240 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 169620.22
Deduct 236 from 240 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 final outcome is 169620.22, with a leftover of 0.004.
