We're dividing 428840 by 13 
Our goal is to divide 428840 by 13.

Advancing to step 1:
When dividing 4 by 13, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 13

On to step 2:
13 goes into 42 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 3 after subtracting 39 from 42.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 13

Going ahead to step 3:
38 divided by 13 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 32.0
Subtracting 26 from 38 leaves us with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 13

Let's proceed to step 4:
128 divided by 13 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 329.0
Subtract 117 from 128 to get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 13

Going ahead to step 5:
When dividing 114 by 13, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 3298.0
Subtract 104 from 114 to get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 13

Let's proceed to step 6:
100 divided by 13 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 32987.0
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.

Advancing to step 7:
When dividing 90 by 13, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 32987.6
Subtract 78 from 90 to 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.

Advancing to step 8:
If we divide 120 by 13, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 32987.69
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
When dividing 30 by 13, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 32987.692
If we take 26 away from 30, we end up 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.

Let's proceed to step 10:
When dividing 40 by 13, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 32987.6923
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.

Let's proceed to step 11:
If we divide 10 by 13, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 32987.6923
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.

Let's proceed to step 12:
If we divide 100 by 13, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 32987.692307
If we subtract 91 from 100, 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 13:
The number 13 fits into 90 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 32987.6923076
If we take 78 away from 90, we end up 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 14:
When dividing 120 by 13, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 32987.69230769
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.

The final outcome is 32987.69230769, with a leftover of 3e-09.
