We're dividing 88460469 by 15 
We want to figure out the number of times 88460469 can be divided by 15.

Step 1:
When dividing 8 by 15, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 15

Advancing to step 2:
If we divide 88 by 15, we get 5 and a remainder of 13.
The next digit of our result is 5. 
Result so far: 5.0
If we take 75 away from 88, we end up with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 15

Moving on to step 3:
If we divide 134 by 15, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
If we subtract 120 from 134, we get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 15

Moving on to step 4:
15 can be fit into 146 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 589.0
If we take 135 away from 146, we end up with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 15

Moving on to step 5:
The number 15 fits into 110 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 5897.0
The remainder is 5 after subtracting 105 from 110.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 15

Step 6:
54 divided by 15 is 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 58973.0
Deduct 45 from 54 and we're left with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 15

Moving on to step 7:
The number 15 fits into 96 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 589736.0
Subtract 90 from 96 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 15

Step 8:
15 goes into 69 4 times with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 5897364.0
The remainder is 9 after subtracting 60 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
15 goes into 90 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 5897364.6
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
15 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5897364.6
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.

On to step 11:
When dividing 0 by 15, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5897364.6
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.

In conclusion, the division gives 5897364.6 with a balance of 0.0.
