We're dividing 514791 by 12 
Our goal is to divide 514791 by 12.

Let's proceed to step 1:
5 divided by 12 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 12

Step 2:
12 goes into 51 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 3 after subtracting 48 from 51.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 12

Going ahead to step 3:
When dividing 34 by 12, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 24 from 34 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 12

Moving on to step 4:
If we divide 107 by 12, we get 8 and a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 428.0
Subtracting 96 from 107 leaves us with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 12

Advancing to step 5:
12 goes into 119 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 4289.0
If we subtract 108 from 119, we get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 12

Advancing to step 6:
The number 12 fits into 111 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 42899.0
Deduct 108 from 111 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 12, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 42899.2
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 42899.25
Subtracting 60 from 60 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42899.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42899.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 42899.25, with a leftover of 0.0.
