We're dividing 181420 by 12 
We want to figure out the number of times 181420 can be divided by 12.

Let's proceed to step 1:
The number 12 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 12

Going ahead to step 2:
12 goes into 18 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 6 after subtracting 12 from 18.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 12

Let's proceed to step 3:
12 goes into 61 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 60 from 61 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 12

Going ahead to step 4:
When dividing 14 by 12, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 151.0
Deduct 12 from 14 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 12

Advancing to step 5:
12 can be fit into 22 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 1511.0
Subtract 12 from 22 to get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 12

Moving on to step 6:
100 divided by 12 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 15118.0
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 15118.3
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 15118.33
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 15118.33 with a balance of 0.004.
