We look at the division of 866153 by 14 
We want to figure out the number of times 866153 can be divided by 14.

On to step 1:
When dividing 8 by 14, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 14

Moving on to step 2:
The number 14 fits into 86 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 2 after subtracting 84 from 86.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 14

Step 3:
14 can be fit into 26 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Deduct 14 from 26 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 14

Step 4:
121 divided by 14 is 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 618.0
The remainder is 9 after subtracting 112 from 121.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 14

Step 5:
The number 14 fits into 95 6 times, leaving a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 6186.0
Subtracting 84 from 95 leaves us with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 14

Moving on to step 6:
14 goes into 113 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 61868.0
The remainder is 1 after subtracting 112 from 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 14 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 61868.0
Subtracting 0 from 10 leaves us 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.

Advancing to step 8:
If we divide 100 by 14, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 61868.07
Deduct 98 from 100 and we're left 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.

Step 9:
14 goes into 20 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 61868.071
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.

On to step 10:
60 divided by 14 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 61868.0714
Deduct 56 from 60 and we're left 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.

Going ahead to step 11:
The number 14 fits into 40 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 61868.07142
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.

Step 12:
If we divide 120 by 14, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 61868.071428
Subtracting 112 from 120 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.

Going ahead to step 13:
14 goes into 80 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 61868.0714285
Subtracting 70 from 80 leaves us 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.

On to step 14:
100 divided by 14 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 61868.07142857
The remainder is 2 after subtracting 98 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 61868.07142857 and a remainder of 2e-09.
