70584 divided by 18 
The aim is to understand the frequency of 18 in 70584.

Advancing to step 1:
The number 18 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 18

On to step 2:
70 divided by 18 is 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 3.0
If we take 54 away from 70, we end up with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 18

On to step 3:
165 divided by 18 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 3 after subtracting 162 from 165.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 18

Moving on to step 4:
If we divide 38 by 18, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 392.0
Subtract 36 from 38 to get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 18

Advancing to step 5:
18 goes into 24 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 3921.0
If we subtract 18 from 24, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 6:
18 goes into 60 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3921.3
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
18 goes into 60 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3921.33
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.
