We look at the division of 721427 by 13 
Let's see how many times 13 fits into 721427.

Advancing to step 1:
13 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 13

Advancing to step 2:
If we divide 72 by 13, we get 5 and a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 7 after subtracting 65 from 72.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 13

Step 3:
If we divide 71 by 13, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtracting 65 from 71 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 13

Going ahead to step 4:
13 goes into 64 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 554.0
If we take 52 away from 64, we end up with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 13

Advancing to step 5:
13 goes into 122 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 5549.0
If we take 117 away from 122, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 13

Let's proceed to step 6:
When dividing 57 by 13, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 55494.0
If we subtract 52 from 57, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
13 can be fit into 50 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 55494.3
If we subtract 39 from 50, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 55494.38
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
60 divided by 13 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 55494.384
If we subtract 52 from 60, 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:
80 divided by 13 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 55494.3846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
The number 13 fits into 20 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 55494.38461
If we subtract 13 from 20, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
If we divide 70 by 13, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 55494.384615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
If we divide 50 by 13, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 55494.3846153
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
13 goes into 110 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 55494.38461538
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 55494.38461538, with a leftover of 6e-09.
