Let's divide 17087421 by 14
We're looking to find how many times 14 goes into 17087421.

Step 1:
The number 14 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 14

Moving on to step 2:
If we divide 17 by 14, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 14 from 17, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 14

Advancing to step 3:
If we divide 30 by 14, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 28 from 30, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 14

Moving on to step 4:
14 goes into 28 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 122.0
The remainder is 0 after subtracting 28 from 28.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 14

Moving on to step 5:
If we divide 7 by 14, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 1220.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 14

Let's proceed to step 6:
When dividing 74 by 14, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 12205.0
Subtracting 70 from 74 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 14

Let's proceed to step 7:
14 can be fit into 42 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 122053.0
Deduct 42 from 42 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 14

Going ahead to step 8:
The number 14 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 1220530.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
The number 14 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1220530.0
If we take 0 away from 10, we end up 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 10:
If we divide 100 by 14, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 1220530.07
Subtract 98 from 100 to get 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 11:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1220530.071
If we subtract 14 from 20, we 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 12:
60 divided by 14 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 1220530.0714
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.

Going ahead to step 13:
14 can be fit into 40 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 1220530.07142
Subtracting 28 from 40 leaves us 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.

On to step 14:
120 divided by 14 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1220530.071428
Deduct 112 from 120 and we're left 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.

Step 15:
The number 14 fits into 80 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 1220530.0714285
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 16:
14 can be fit into 100 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 1220530.07142857
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.

The final outcome is 1220530.07142857, with a leftover of 2e-09.
