75819536 divided by 515 
We want to figure out the number of times 75819536 can be divided by 515.

Step 1:
515 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 515

Advancing to step 2:
515 can be fit into 75 0 times, resulting in a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Take the next digit (8) from the dividend and append it to 75, then repeat: 758 / 515

Let's proceed to step 3:
The number 515 fits into 758 1 times, leaving a remainder of 243.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 243 after subtracting 515 from 758.
Include the next digit (1) from the dividend after 243, then repeat: 2431 / 515

Going ahead to step 4:
If we divide 2431 by 515, we get 4 and a remainder of 371.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 371 after subtracting 2060 from 2431.
Grab the next digit (9) from the dividend, add it to 371, then carry on: 3719 / 515

Moving on to step 5:
When dividing 3719 by 515, we get 7 with a remainder of 114.
Put 7 as the next digit of the answer. 
Result so far: 147.0
The remainder is 114 after subtracting 3605 from 3719.
Bring next digit (5) of the dividend behind the 114 and repeat the process: 1145 / 515

Step 6:
If we divide 1145 by 515, we get 2 and a remainder of 115.
Put 2 as the next digit of the answer. 
Result so far: 1472.0
The remainder is 115 after subtracting 1030 from 1145.
Include the next digit (3) from the dividend after 115, then repeat: 1153 / 515

On to step 7:
515 goes into 1153 2 times with a remainder of 123.
Use 2 as the next digit of our solution. 
Result so far: 14722.0
Subtract 1030 from 1153 to get 123.
Append the next digit (6) from the dividend to 123 and continue with: 1236 / 515

Let's proceed to step 8:
1236 divided by 515 is 2 with a remainder of 206.
The number 2 becomes the next digit in our result. 
Result so far: 147222.0
If we take 1030 away from 1236, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 9:
When dividing 2060 by 515, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 147222.4
If we take 2060 away from 2060, 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.

Going ahead to step 10:
515 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 147222.4
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.

Going ahead to step 11:
The number 515 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 147222.4
Deduct 0 from 0 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.

Our division results in 147222.4 with a remaining 0.0.
