We look at the division of 868172 by 18 
Our goal is to divide 868172 by 18.

Let's proceed to step 1:
8 divided by 18 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 18

Moving on to step 2:
18 can be fit into 86 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 72 away from 86, we end up with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 18

Step 3:
148 divided by 18 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtract 144 from 148 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 18

On to step 4:
If we divide 41 by 18, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 482.0
Deduct 36 from 41 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 18

Advancing to step 5:
18 goes into 57 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 4823.0
If we subtract 54 from 57, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 18

Let's proceed to step 6:
32 divided by 18 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 48231.0
The remainder is 14 after subtracting 18 from 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
18 goes into 140 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 48231.7
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
The number 18 fits into 140 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 48231.77
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 48231.77 with a balance of 0.014.
