We look at the division of 75691690 by 515 
We want to figure out the number of times 75691690 can be divided by 515.

Let's proceed to step 1:
If we divide 7 by 515, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 515

Moving on to step 2:
If we divide 75 by 515, we get 0 and a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Bring next digit (6) of the dividend behind the 75 and repeat the process: 756 / 515

Let's proceed to step 3:
If we divide 756 by 515, we get 1 and a remainder of 241.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 515 from 756, we get 241.
Grab the next digit (9) from the dividend, add it to 241, then carry on: 2419 / 515

On to step 4:
The number 515 fits into 2419 4 times, leaving a remainder of 359.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 2060 from 2419 leaves us with 359.
Include the next digit (1) from the dividend after 359, then repeat: 3591 / 515

Let's proceed to step 5:
515 goes into 3591 6 times with a remainder of 501.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
Deduct 3090 from 3591 and we're left with 501.
Fetch the next digit (6) from the dividend, attach it to 501 and continue: 5016 / 515

Advancing to step 6:
5016 divided by 515 is 9 with a remainder of 381.
Record the quotient 9 as the next digit in the result. 
Result so far: 1469.0
Subtract 4635 from 5016 to get 381.
Include the next digit (9) from the dividend after 381, then repeat: 3819 / 515

Step 7:
If we divide 3819 by 515, we get 7 and a remainder of 214.
The number 7 becomes the next digit in our result. 
Result so far: 14697.0
Subtracting 3605 from 3819 leaves us with 214.
Append the next digit (0) from the dividend to 214 and continue with: 2140 / 515

Moving on to step 8:
515 can be fit into 2140 4 times, resulting in a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 146974.0
Subtracting 2060 from 2140 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
800 divided by 515 is 1 with a remainder of 285.
Write down 1 as next digit of the result. 
Result so far: 146974.1
The remainder is 285 after subtracting 515 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 10:
When dividing 2850 by 515, we get 5 with a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 146974.15
Subtracting 2575 from 2850 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 11:
If we divide 2750 by 515, we get 5 and a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 146974.155
Subtract 2575 from 2750 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

After the division, we end up with 146974.155 and a remainder of 0.0175.
