We divide 234578 by 12
We want to divide 234578 by 12.

Going ahead to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 12

Moving on to step 2:
23 divided by 12 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
If we take 12 away from 23, we end up with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 12

Let's proceed to step 3:
If we divide 114 by 12, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 6 after subtracting 108 from 114.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 12

Let's proceed to step 4:
12 goes into 65 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
Subtract 60 from 65 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 12

On to step 5:
12 can be fit into 57 4 times, resulting in a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 1954.0
Deduct 48 from 57 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 12

Moving on to step 6:
12 can be fit into 98 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 19548.0
The remainder is 2 after subtracting 96 from 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
12 can be fit into 20 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 19548.1
Subtracting 12 from 20 leaves us 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 8:
80 divided by 12 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 19548.16
If we take 72 away from 80, we end up 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.

On to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 19548.166
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.

The quotient of the division is 19548.166, and the remainder is 0.0008.
