We're dividing 156121 by 14 
We're looking to find how many times 14 goes into 156121.

On to step 1:
The number 14 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 14

On to step 2:
If we divide 15 by 14, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 14 from 15 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 14

Advancing to step 3:
14 can be fit into 16 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 14 from 16 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 14

On to step 4:
The number 14 fits into 21 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 111.0
Subtracting 14 from 21 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 14

Step 5:
When dividing 72 by 14, we get 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 1115.0
Subtract 70 from 72 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 14

Advancing to step 6:
If we divide 21 by 14, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 11151.0
If we take 14 away from 21, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 14 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11151.5
Deduct 70 from 70 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 14 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11151.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 14, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11151.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 11151.5 with a remainder of 0.0.
