We divide 136770 by 15
We want to figure out the number of times 136770 can be divided by 15.

On to step 1:
When dividing 1 by 15, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 15

Let's proceed to step 2:
When dividing 13 by 15, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 15

Advancing to step 3:
If we divide 136 by 15, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 1 after subtracting 135 from 136.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 15

Let's proceed to step 4:
17 divided by 15 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we subtract 15 from 17, we get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 15

Advancing to step 5:
The number 15 fits into 27 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 911.0
If we subtract 15 from 27, we get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 15

Moving on to step 6:
15 can be fit into 120 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 9118.0
Deduct 120 from 120 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.

Step 7:
0 divided by 15 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9118.0
If we take 0 away from 0, we end up 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.

On to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9118.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 9118.0 and a remainder of 0.0.
