We divide 679042 by 18
The aim is to understand the frequency of 18 in 679042.

Step 1:
If we divide 6 by 18, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 18

On to step 2:
18 can be fit into 67 3 times, resulting in a remainder of 13.
The next digit of our result is 3. 
Result so far: 3.0
If we take 54 away from 67, we end up with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 18

Let's proceed to step 3:
If we divide 139 by 18, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 37.0
The remainder is 13 after subtracting 126 from 139.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 18

Let's proceed to step 4:
18 can be fit into 130 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 377.0
If we subtract 126 from 130, we get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 18

Let's proceed to step 5:
44 divided by 18 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 3772.0
Subtract 36 from 44 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 18

Let's proceed to step 6:
18 can be fit into 82 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 37724.0
Subtract 72 from 82 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
18 goes into 100 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 37724.5
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 18, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 37724.55
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 37724.55 with a remaining 0.01.
