We divide 121336 by 15
We want to divide 121336 by 15.

Let's proceed to step 1:
If we divide 1 by 15, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 15

On to step 2:
The number 15 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 15

Moving on to step 3:
121 divided by 15 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 120 from 121 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 15

Advancing to step 4:
15 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtract 0 from 13 to get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 15

Advancing to step 5:
15 goes into 133 8 times with a remainder of 13.
The next digit of our result is 8. 
Result so far: 808.0
Subtracting 120 from 133 leaves us with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 15

Step 6:
15 can be fit into 136 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 8089.0
Subtract 135 from 136 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 15 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 8089.0
If we subtract 0 from 10, 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.

Step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 8089.06
If we take 90 away from 100, 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.

Moving on to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 8089.066
Deduct 90 from 100 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.

Our division results in 8089.066 with a remaining 0.001.
