We divide 57243190 by 12
We want to divide 57243190 by 12.

Let's proceed to step 1:
12 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 12

Step 2:
If we divide 57 by 12, we get 4 and a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 48 away from 57, we end up with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 12

Step 3:
12 can be fit into 92 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 84 away from 92, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 12

Going ahead to step 4:
12 can be fit into 84 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 477.0
If we subtract 84 from 84, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 12

Step 5:
12 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 4770.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 12

Advancing to step 6:
31 divided by 12 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 47702.0
Subtract 24 from 31 to get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 12

Let's proceed to step 7:
79 divided by 12 is 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 477026.0
Deduct 72 from 79 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 12

Step 8:
When dividing 70 by 12, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 4770265.0
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
When dividing 100 by 12, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 4770265.8
If we take 96 away from 100, we end up 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.

Let's proceed to step 10:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 4770265.83
Subtract 36 from 40 to 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 11:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 4770265.833
Subtracting 36 from 40 leaves us 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.

Our division results in 4770265.833 with a remaining 0.0004.
