We're dividing 839864 by 13 
We're looking to find how many times 13 goes into 839864.

Step 1:
When dividing 8 by 13, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 13

Advancing to step 2:
If we divide 83 by 13, we get 6 and a remainder of 5.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 5 after subtracting 78 from 83.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 13

Step 3:
If we divide 59 by 13, we get 4 and a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we take 52 away from 59, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 13

Let's proceed to step 4:
The number 13 fits into 78 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 646.0
The remainder is 0 after subtracting 78 from 78.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 13

On to step 5:
13 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 6460.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 13

Going ahead to step 6:
If we divide 64 by 13, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 64604.0
The remainder is 12 after subtracting 52 from 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
13 can be fit into 120 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 64604.9
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 8:
If we divide 30 by 13, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 64604.92
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.

Advancing to step 9:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 64604.923
Subtracting 39 from 40 leaves us 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.

On to step 10:
If we divide 10 by 13, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 64604.923
Subtract 0 from 10 to 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.

Going ahead to step 11:
13 goes into 100 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 64604.92307
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.

Advancing to step 12:
The number 13 fits into 90 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 64604.923076
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.

Advancing to step 13:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 64604.9230769
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.

Moving on to step 14:
If we divide 30 by 13, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 64604.92307692
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 64604.92307692, and the remainder is 4e-09.
