We're dividing 518403 by 36 
Let's see how many times 36 fits into 518403.

On to step 1:
36 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 36

Step 2:
The number 36 fits into 51 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 36 from 51, we get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 36

Advancing to step 3:
158 divided by 36 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 14.0
If we take 144 away from 158, we end up with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 36

On to step 4:
The number 36 fits into 144 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
If we take 144 away from 144, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 36

Going ahead to step 5:
When dividing 0 by 36, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1440.0
If we take 0 away from 0, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 36

On to step 6:
When dividing 3 by 36, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 14400.0
If we subtract 0 from 3, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
36 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 14400.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 36, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 14400.08
Subtract 288 from 300 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 36 is 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 14400.083
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
When dividing 120 by 36, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 14400.0833
Subtracting 108 from 120 leaves us 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.

In conclusion, the division gives 14400.0833 with a balance of 0.00012.
