We're dividing 43253 by 12 
We want to divide 43253 by 12.

Let's proceed to step 1:
4 divided by 12 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 12

Going ahead to step 2:
The number 12 fits into 43 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 36 from 43 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 12

Going ahead to step 3:
When dividing 72 by 12, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 72 from 72, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 12

On to step 4:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 360.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 12

Let's proceed to step 5:
53 divided by 12 is 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 3604.0
Subtract 48 from 53 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 6:
When dividing 50 by 12, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3604.4
Subtracting 48 from 50 leaves us with 2.
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:
When dividing 20 by 12, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 3604.41
If we subtract 12 from 20, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 3604.416
Subtract 72 from 80 to get 8.
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 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 3604.4166
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.

The quotient of the division is 3604.4166, and the remainder is 8e-05.
