We're dividing 677844 by 18 
The aim is to understand the frequency of 18 in 677844.

Advancing to step 1:
If we divide 6 by 18, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 18

Going ahead to step 2:
The number 18 fits into 67 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 54 from 67 leaves us with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 18

Step 3:
If we divide 137 by 18, we get 7 and a remainder of 11.
The next digit of our result is 7. 
Result so far: 37.0
Subtracting 126 from 137 leaves us with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 18

Step 4:
When dividing 118 by 18, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 376.0
Deduct 108 from 118 and we're left with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 18

Advancing to step 5:
18 goes into 104 5 times with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 3765.0
The remainder is 14 after subtracting 90 from 104.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 18

Moving on to step 6:
18 goes into 144 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 37658.0
Subtracting 144 from 144 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.

On to step 7:
If we divide 0 by 18, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 37658.0
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.

Going ahead to step 8:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37658.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 37658.0 and a remainder of 0.0.
