We look at the division of 18729110 by 12 
Our goal is to divide 18729110 by 12.

On to step 1:
1 divided by 12 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 12

Going ahead to step 2:
12 can be fit into 18 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 12 from 18, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 12

Going ahead to step 3:
12 can be fit into 67 5 times, resulting in a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 60 from 67 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 12

Moving on to step 4:
If we divide 72 by 12, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 156.0
If we subtract 72 from 72, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 12

Advancing to step 5:
If we divide 9 by 12, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 1560.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 12

On to step 6:
12 goes into 91 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 15607.0
Subtract 84 from 91 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 12

Advancing to step 7:
The number 12 fits into 71 5 times, leaving a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 156075.0
Deduct 60 from 71 and we're left with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 12

Let's proceed to step 8:
12 can be fit into 110 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 1560759.0
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1560759.1
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 1560759.16
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 1560759.166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 1560759.166 with a balance of 0.0008.
