Let's divide 821399 by 14
We want to figure out the number of times 821399 can be divided by 14.

Advancing to step 1:
The number 14 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 14

Moving on to step 2:
14 goes into 82 5 times with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 70 away from 82, we end up with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 14

Moving on to step 3:
14 goes into 121 8 times with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 58.0
The remainder is 9 after subtracting 112 from 121.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 14

Moving on to step 4:
The number 14 fits into 93 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 586.0
If we take 84 away from 93, we end up with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 14

Advancing to step 5:
The number 14 fits into 99 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 5867.0
If we subtract 98 from 99, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 14

On to step 6:
19 divided by 14 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 58671.0
Subtract 14 from 19 to 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.

Let's proceed to step 7:
The number 14 fits into 50 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 58671.3
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
When dividing 80 by 14, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 58671.35
Deduct 70 from 80 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 9:
100 divided by 14 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 58671.357
Subtracting 98 from 100 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.

Let's proceed to step 10:
The number 14 fits into 20 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 58671.3571
Subtract 14 from 20 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.

Going ahead to step 11:
If we divide 60 by 14, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 58671.35714
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
14 goes into 40 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 58671.357142
Subtract 28 from 40 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.

Let's proceed to step 13:
14 goes into 120 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 58671.3571428
If we take 112 away from 120, we end up with 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 14:
When dividing 80 by 14, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 58671.35714285
The remainder is 10 after subtracting 70 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 58671.35714285 and a remainder of 1e-08.
