We divide 139170 by 18
Our goal is to divide 139170 by 18.

Let's proceed to step 1:
If we divide 1 by 18, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 18

Advancing to step 2:
13 divided by 18 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 18

On to step 3:
When dividing 139 by 18, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 126 away from 139, we end up with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 18

Moving on to step 4:
If we divide 131 by 18, we get 7 and a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
The remainder is 5 after subtracting 126 from 131.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 18

Moving on to step 5:
57 divided by 18 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 773.0
The remainder is 3 after subtracting 54 from 57.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 18

Let's proceed to step 6:
When dividing 30 by 18, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 7731.0
Subtract 18 from 30 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.

Advancing to step 7:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 7731.6
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.

Going ahead to step 8:
If we divide 120 by 18, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 7731.66
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.

In conclusion, the division gives 7731.66 with a balance of 0.012.
