Let's divide 111681 by 18
The aim is to understand the frequency of 18 in 111681.

Let's proceed to step 1:
The number 18 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 18

On to step 2:
The number 18 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 18

Step 3:
18 can be fit into 111 6 times, resulting in a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 108 away from 111, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 18

Moving on to step 4:
18 goes into 36 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
The remainder is 0 after subtracting 36 from 36.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 18

Let's proceed to step 5:
The number 18 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 620.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 18

Let's proceed to step 6:
The number 18 fits into 81 4 times, leaving a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 6204.0
Subtract 72 from 81 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
If we divide 90 by 18, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6204.5
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 18 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6204.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 18, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6204.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 6204.5 with a remaining 0.0.
