We're dividing 499972 by 13 
We want to figure out the number of times 499972 can be divided by 13.

Advancing to step 1:
If we divide 4 by 13, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 13

Going ahead to step 2:
When dividing 49 by 13, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 39 from 49 to get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 13

Step 3:
When dividing 109 by 13, we get 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 104 away from 109, we end up with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 13

On to step 4:
13 can be fit into 59 4 times, resulting in a remainder of 7.
The next digit of our result is 4. 
Result so far: 384.0
Subtract 52 from 59 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 13

Moving on to step 5:
The number 13 fits into 77 5 times, leaving a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 3845.0
Subtracting 65 from 77 leaves us with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 13

Moving on to step 6:
When dividing 122 by 13, we get 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 38459.0
Deduct 117 from 122 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
If we divide 50 by 13, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 38459.3
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 8:
13 goes into 110 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 38459.38
Subtracting 104 from 110 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:
13 goes into 60 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 38459.384
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.

On to step 10:
80 divided by 13 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 38459.3846
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 38459.38461
Deduct 13 from 20 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

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: 38459.384615
Subtracting 65 from 70 leaves us with 5.
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 number 3 becomes the next digit in our result. 
Result so far: 38459.3846153
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
13 can be fit into 110 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 38459.38461538
The remainder is 6 after subtracting 104 from 110.
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 result is 38459.38461538 with a remainder of 6e-09.
