839186 ÷ 13 
Let's see how many times 13 fits into 839186.

Step 1:
13 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 13

Moving on to step 2:
The number 13 fits into 83 6 times, leaving a remainder of 5.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 78 from 83 to get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 13

Going ahead to step 3:
The number 13 fits into 59 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we subtract 52 from 59, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 13

Let's proceed to step 4:
When dividing 71 by 13, we get 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 645.0
If we subtract 65 from 71, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 13

Going ahead to step 5:
68 divided by 13 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 6455.0
If we subtract 65 from 68, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 13

On to step 6:
13 can be fit into 36 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 64552.0
The remainder is 10 after subtracting 26 from 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 64552.7
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
The number 13 fits into 90 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 64552.76
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 9:
When dividing 120 by 13, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 64552.769
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 10:
If we divide 30 by 13, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 64552.7692
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.

Advancing to step 11:
13 goes into 40 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 64552.76923
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
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: 64552.76923
Deduct 0 from 10 and we're left with 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 13:
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: 64552.7692307
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
13 goes into 90 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 64552.76923076
If we subtract 78 from 90, we 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.

The final result is 64552.76923076 with a remainder of 1.2e-08.
