13 can be fit into 16 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 561.0
Subtracting 13 from 16 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 13

Step 5:
33 divided by 13 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 5612.0
The remainder is 7 after subtracting 26 from 33.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 13

On to step 6:
13 goes into 76 5 times with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 56125.0
The remainder is 11 after subtracting 65 from 76.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 13

Step 7:
118 divided by 13 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 561259.0
Subtract 117 from 118 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 13

Step 8:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 5612590.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
13 can be fit into 100 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 5612590.7
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 5612590.76
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.

Advancing to step 11:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 5612590.769
If we subtract 117 from 120, we 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.

Advancing to step 12:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 5612590.7692
If we subtract 26 from 30, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 5612590.76923
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
13 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 5612590.76923
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 15:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 5612590.7692307
Subtract 91 from 100 to 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.

Moving on to step 16:
When dividing 90 by 13, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 5612590.76923076
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.

The final outcome is 5612590.76923076, with a leftover of 1.2e-08.
