We're dividing 12719578 by 5 
We want to divide 12719578 by 5.

Advancing to step 1:
If we divide 1 by 5, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 5

Advancing to step 2:
12 divided by 5 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 10 from 12 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 5

Let's proceed to step 3:
5 goes into 27 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 25 from 27 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 5

Going ahead to step 4:
5 goes into 21 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 254.0
Subtract 20 from 21 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 5

On to step 5:
If we divide 19 by 5, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 2543.0
If we subtract 15 from 19, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 5

On to step 6:
5 can be fit into 45 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 25439.0
The remainder is 0 after subtracting 45 from 45.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 5

Moving on to step 7:
The number 5 fits into 7 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 254391.0
Deduct 5 from 7 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 5

Moving on to step 8:
5 goes into 28 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 2543915.0
Subtracting 25 from 28 leaves us 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.

On to step 9:
5 goes into 30 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 2543915.6
Deduct 30 from 30 and we're left 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 10:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 2543915.6
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.

On to step 11:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2543915.6
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.

The final result is 2543915.6 with a remainder of 0.0.
