Let's divide 807548 by 18
The aim is to understand the frequency of 18 in 807548.

Moving on to step 1:
If we divide 8 by 18, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 18

Going ahead to step 2:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 72 from 80 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 18

Moving on to step 3:
The number 18 fits into 87 4 times, leaving a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtracting 72 from 87 leaves us with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 18

Step 4:
18 goes into 155 8 times with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 448.0
Subtract 144 from 155 to get 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 18

On to step 5:
114 divided by 18 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 4486.0
Subtracting 108 from 114 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 18

Step 6:
18 goes into 68 3 times with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 44863.0
If we subtract 54 from 68, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
140 divided by 18 is 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 44863.7
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
When dividing 140 by 18, we get 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 44863.77
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 44863.77, with a leftover of 0.014.
