764070 divided by 15 
We want to figure out the number of times 764070 can be divided by 15.

On to step 1:
7 divided by 15 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 15

Moving on to step 2:
The number 15 fits into 76 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 1 after subtracting 75 from 76.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 15

Going ahead to step 3:
14 divided by 15 is 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 50.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 15

Moving on to step 4:
140 divided by 15 is 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 509.0
The remainder is 5 after subtracting 135 from 140.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 15

Let's proceed to step 5:
If we divide 57 by 15, we get 3 and a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 5093.0
Deduct 45 from 57 and we're left with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 15

On to step 6:
120 divided by 15 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 50938.0
Subtract 120 from 120 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.

Step 7:
When dividing 0 by 15, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50938.0
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.

Let's proceed to step 8:
15 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 50938.0
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.

The final result is 50938.0 with a remainder of 0.0.
