We look at the division of 79808309 by 13 
Our goal is to divide 79808309 by 13.

Moving on to step 1:
When dividing 7 by 13, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 13

On to step 2:
If we divide 79 by 13, we get 6 and a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 1 after subtracting 78 from 79.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 13

Step 3:
13 goes into 18 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 61.0
If we take 13 away from 18, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 13

Going ahead to step 4:
When dividing 50 by 13, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 613.0
If we take 39 away from 50, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 13

Going ahead to step 5:
If we divide 118 by 13, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 6139.0
If we subtract 117 from 118, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 13

Let's proceed to step 6:
13 divided by 13 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 61391.0
Subtract 13 from 13 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 13

Moving on to step 7:
If we divide 0 by 13, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 613910.0
If we subtract 0 from 0, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 13

On to step 8:
If we divide 9 by 13, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 6139100.0
If we subtract 0 from 9, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 6139100.6
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
120 divided by 13 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 6139100.69
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 6139100.692
Subtracting 26 from 30 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.

On to step 12:
If we divide 40 by 13, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 6139100.6923
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 6139100.6923
Subtracting 0 from 10 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 14:
13 goes into 100 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 6139100.692307
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 15:
13 goes into 90 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 6139100.6923076
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 16:
If we divide 120 by 13, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 6139100.69230769
Subtracting 117 from 120 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.

The final result is 6139100.69230769 with a remainder of 3e-09.
