813209 divided by 18 
Our goal is to divide 813209 by 18.

Moving on to step 1:
If we divide 8 by 18, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 18

Step 2:
When dividing 81 by 18, we get 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 72 from 81 to get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 18

Going ahead to step 3:
When dividing 93 by 18, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 45.0
The remainder is 3 after subtracting 90 from 93.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 18

Going ahead to step 4:
When dividing 32 by 18, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 451.0
Deduct 18 from 32 and we're left with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 18

On to step 5:
18 goes into 140 7 times with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 4517.0
Subtracting 126 from 140 leaves us with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 18

Going ahead to step 6:
When dividing 149 by 18, we get 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 45178.0
Deduct 144 from 149 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
18 can be fit into 50 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 45178.2
If we subtract 36 from 50, 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.

On to step 8:
18 goes into 140 7 times with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 45178.27
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
140 divided by 18 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 45178.277
Subtract 126 from 140 to 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.

Our division results in 45178.277 with a remaining 0.0014.
