We're dividing 521202 by 18 
Let's see how many times 18 fits into 521202.

Moving on to step 1:
When dividing 5 by 18, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 18

Moving on to step 2:
52 divided by 18 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 36 from 52 to get 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 18

On to step 3:
When dividing 161 by 18, we get 8 with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 144 from 161 and we're left with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 18

Going ahead to step 4:
If we divide 172 by 18, we get 9 and a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 289.0
Subtract 162 from 172 to get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 18

Moving on to step 5:
When dividing 100 by 18, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 2895.0
Subtract 90 from 100 to get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 18

Moving on to step 6:
If we divide 102 by 18, we get 5 and a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 28955.0
If we subtract 90 from 102, 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.

On to step 7:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 28955.6
Subtract 108 from 120 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.

Let's proceed to step 8:
120 divided by 18 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 28955.66
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.

In conclusion, the division gives 28955.66 with a balance of 0.012.
