84356 ÷ 18 
We want to figure out the number of times 84356 can be divided by 18.

Advancing to step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 18

Moving on to step 2:
When dividing 84 by 18, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 72 from 84 to get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 18

Advancing to step 3:
When dividing 123 by 18, we get 6 with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we subtract 108 from 123, we get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 18

Advancing to step 4:
If we divide 155 by 18, we get 8 and a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 468.0
Deduct 144 from 155 and we're left with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 18

Moving on to step 5:
116 divided by 18 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 4686.0
If we subtract 108 from 116, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 6:
18 goes into 80 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 4686.4
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4686.44
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 4686.44 with a remaining 0.008.
