143902 divided by 14 
Let's see how many times 14 fits into 143902.

Moving on to step 1:
If we divide 1 by 14, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 14

Going ahead to step 2:
14 can be fit into 14 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 14 from 14 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 14

Moving on to step 3:
14 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 14

Let's proceed to step 4:
39 divided by 14 is 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Deduct 28 from 39 and we're left with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 14

Moving on to step 5:
If we divide 110 by 14, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 1027.0
Subtract 98 from 110 to get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 14

Going ahead to step 6:
The number 14 fits into 122 8 times, leaving a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 10278.0
Subtract 112 from 122 to 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.

Step 7:
14 goes into 100 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 10278.7
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.

Let's proceed to step 8:
When dividing 20 by 14, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 10278.71
Deduct 14 from 20 and we're left 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.

Moving on to step 9:
60 divided by 14 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 10278.714
Subtracting 56 from 60 leaves us 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.

On to step 10:
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: 10278.7142
Deduct 28 from 40 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.

Step 11:
When dividing 120 by 14, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 10278.71428
The remainder is 8 after subtracting 112 from 120.
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:
The number 14 fits into 80 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 10278.714285
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.

Let's proceed to step 13:
14 can be fit into 100 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 10278.7142857
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.

Advancing to step 14:
When dividing 20 by 14, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 10278.71428571
Subtracting 14 from 20 leaves us 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.

After the division, we end up with 10278.71428571 and a remainder of 6e-09.
