610860 ÷ 18 
The aim is to understand the frequency of 18 in 610860.

Going ahead to step 1:
18 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 18

Moving on to step 2:
18 can be fit into 61 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
If we take 54 away from 61, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 18

Step 3:
When dividing 70 by 18, we get 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtracting 54 from 70 leaves us with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 18

Moving on to step 4:
The number 18 fits into 168 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 339.0
Subtract 162 from 168 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 18

Advancing to step 5:
18 goes into 66 3 times with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3393.0
If we take 54 away from 66, we end up with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 18

Moving on to step 6:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 33936.0
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
120 divided by 18 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 33936.6
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
If we divide 120 by 18, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 33936.66
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 33936.66, and the remainder is 0.012.
