We're dividing 15319626 by 12 
We want to figure out the number of times 15319626 can be divided by 12.

Advancing to step 1:
The number 12 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 12

Let's proceed to step 2:
If we divide 15 by 12, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 12 away from 15, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 12

Let's proceed to step 3:
When dividing 33 by 12, we get 2 with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 24 away from 33, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 12

Let's proceed to step 4:
12 goes into 91 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 127.0
Deduct 84 from 91 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 12

Going ahead to step 5:
12 goes into 79 6 times with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 1276.0
If we subtract 72 from 79, we get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 12

Let's proceed to step 6:
If we divide 76 by 12, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 12766.0
Subtract 72 from 76 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 12

Step 7:
If we divide 42 by 12, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 127663.0
Subtract 36 from 42 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 12

Advancing to step 8:
When dividing 66 by 12, we get 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 1276635.0
Subtracting 60 from 66 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
12 goes into 60 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1276635.5
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.

Moving on to step 10:
12 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1276635.5
If we take 0 away from 0, we end up 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.

Advancing to step 11:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1276635.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 1276635.5 with a balance of 0.0.
