We're dividing 16860080 by 14 
We want to figure out the number of times 16860080 can be divided by 14.

Going ahead to step 1:
14 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 14

Let's proceed to step 2:
14 goes into 16 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 14 from 16 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 14

On to step 3:
The number 14 fits into 28 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 0 after subtracting 28 from 28.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 14

On to step 4:
6 divided by 14 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we subtract 0 from 6, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 14

Moving on to step 5:
60 divided by 14 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 1204.0
Subtracting 56 from 60 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 14

Going ahead to step 6:
40 divided by 14 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 12042.0
If we subtract 28 from 40, we get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 14

Going ahead to step 7:
The number 14 fits into 128 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 120429.0
Subtracting 126 from 128 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 14

Advancing to step 8:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1204291.0
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 9:
60 divided by 14 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 1204291.4
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 10:
40 divided by 14 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 1204291.42
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
120 divided by 14 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 1204291.428
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
14 can be fit into 80 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 1204291.4285
If we subtract 70 from 80, 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.

Advancing to step 13:
100 divided by 14 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 1204291.42857
If we take 98 away from 100, we end up 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.

Going ahead to step 14:
When dividing 20 by 14, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1204291.428571
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 15:
60 divided by 14 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 1204291.4285714
If we subtract 56 from 60, we 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 16:
14 goes into 40 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 1204291.42857142
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.

The final result is 1204291.42857142 with a remainder of 1.2e-08.
