We divide 78452008 by 515
We're looking to find how many times 515 goes into 78452008.

Advancing to step 1:
When dividing 7 by 515, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 515

Going ahead to step 2:
78 divided by 515 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 515

Let's proceed to step 3:
When dividing 784 by 515, we get 1 with a remainder of 269.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 515 from 784 and we're left with 269.
Include the next digit (5) from the dividend after 269, then repeat: 2695 / 515

On to step 4:
515 can be fit into 2695 5 times, resulting in a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2575 from 2695 and we're left with 120.
Append the next digit (2) from the dividend to 120 and continue with: 1202 / 515

On to step 5:
When dividing 1202 by 515, we get 2 with a remainder of 172.
Write down 2 as next digit of the result. 
Result so far: 152.0
Subtract 1030 from 1202 to get 172.
Take the next digit (0) from the dividend and append it to 172, then repeat: 1720 / 515

Advancing to step 6:
When dividing 1720 by 515, we get 3 with a remainder of 175.
Write down 3 as next digit of the result. 
Result so far: 1523.0
Subtracting 1545 from 1720 leaves us with 175.
Bring next digit (0) of the dividend behind the 175 and repeat the process: 1750 / 515

Going ahead to step 7:
If we divide 1750 by 515, we get 3 and a remainder of 205.
The number 3 becomes the next digit in our result. 
Result so far: 15233.0
If we subtract 1545 from 1750, we get 205.
Grab the next digit (8) from the dividend, add it to 205, then carry on: 2058 / 515

On to step 8:
The number 515 fits into 2058 3 times, leaving a remainder of 513.
The number 3 becomes the next digit in our result. 
Result so far: 152333.0
Subtracting 1545 from 2058 leaves us with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Moving on to step 9:
If we divide 5130 by 515, we get 9 and a remainder of 495.
The number 9 becomes the next digit in our result. 
Result so far: 152333.9
Deduct 4635 from 5130 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 10:
4950 divided by 515 is 9 with a remainder of 315.
Put 9 as the next digit of the answer. 
Result so far: 152333.99
Deduct 4635 from 4950 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final result is 152333.99 with a remainder of 0.315.
