We divide 84315 by 18
The aim is to understand the frequency of 18 in 84315.

Going ahead to step 1:
18 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 18

Let's proceed to step 2:
The number 18 fits into 84 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 72 away from 84, we end up with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 18

On to step 3:
When dividing 123 by 18, we get 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 46.0
Deduct 108 from 123 and we're left with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 18

Going ahead to step 4:
If we divide 151 by 18, we get 8 and a remainder of 7.
The next digit of our result is 8. 
Result so far: 468.0
The remainder is 7 after subtracting 144 from 151.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 18

Let's proceed to step 5:
The number 18 fits into 75 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4684.0
Subtracting 72 from 75 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 6:
If we divide 30 by 18, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 4684.1
If we take 18 away from 30, 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.

Advancing to step 7:
If we divide 120 by 18, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 4684.16
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.

On to step 8:
When dividing 120 by 18, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 4684.166
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 final result is 4684.166 with a remainder of 0.0012.
