Let's divide 613391 by 12
We want to figure out the number of times 613391 can be divided by 12.

Advancing to step 1:
6 divided by 12 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 12

Advancing to step 2:
If we divide 61 by 12, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 60 from 61, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 12

Moving on to step 3:
13 divided by 12 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we take 12 away from 13, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 12

Step 4:
When dividing 13 by 12, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 511.0
Subtract 12 from 13 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 12

Advancing to step 5:
12 goes into 19 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 5111.0
Subtracting 12 from 19 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 12

Going ahead to step 6:
If we divide 71 by 12, we get 5 and a remainder of 11.
The next digit of our result is 5. 
Result so far: 51115.0
Deduct 60 from 71 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
12 goes into 110 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 51115.9
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
12 goes into 20 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 51115.91
The remainder is 8 after subtracting 12 from 20.
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:
When dividing 80 by 12, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 51115.916
If we subtract 72 from 80, 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.

Advancing to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 51115.9166
If we subtract 72 from 80, 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.

Our division results in 51115.9166 with a remaining 8e-05.
