We divide 74529809 by 515
We want to figure out the number of times 74529809 can be divided by 515.

Going ahead to step 1:
7 divided by 515 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 515

Going ahead to step 2:
The number 515 fits into 74 0 times, leaving a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 515

On to step 3:
When dividing 745 by 515, we get 1 with a remainder of 230.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 515 from 745, we get 230.
Fetch the next digit (2) from the dividend, attach it to 230 and continue: 2302 / 515

Going ahead to step 4:
515 goes into 2302 4 times with a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2060 from 2302, we get 242.
Append the next digit (9) from the dividend to 242 and continue with: 2429 / 515

On to step 5:
2429 divided by 515 is 4 with a remainder of 369.
The next digit of our result is 4. 
Result so far: 144.0
Subtract 2060 from 2429 to get 369.
Bring next digit (8) of the dividend behind the 369 and repeat the process: 3698 / 515

Advancing to step 6:
If we divide 3698 by 515, we get 7 and a remainder of 93.
The number 7 becomes the next digit in our result. 
Result so far: 1447.0
If we take 3605 away from 3698, we end up with 93.
Include the next digit (0) from the dividend after 93, then repeat: 930 / 515

Moving on to step 7:
When dividing 930 by 515, we get 1 with a remainder of 415.
The next digit of our result is 1. 
Result so far: 14471.0
If we subtract 515 from 930, we get 415.
Append the next digit (9) from the dividend to 415 and continue with: 4159 / 515

Going ahead to step 8:
When dividing 4159 by 515, we get 8 with a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 144718.0
If we take 4120 away from 4159, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
The number 515 fits into 390 0 times, leaving a remainder of 390.
The next digit of our result is 0. 
Result so far: 144718.0
The remainder is 390 after subtracting 0 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 10:
The number 515 fits into 3900 7 times, leaving a remainder of 295.
The next digit of our result is 7. 
Result so far: 144718.07
If we subtract 3605 from 3900, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 11:
515 goes into 2950 5 times with a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 144718.075
The remainder is 375 after subtracting 2575 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 12:
The number 515 fits into 3750 7 times, leaving a remainder of 145.
Write down 7 as next digit of the result. 
Result so far: 144718.0757
If we subtract 3605 from 3750, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 13:
515 can be fit into 1450 2 times, resulting in a remainder of 420.
Record the quotient 2 as the next digit in the result. 
Result so far: 144718.07572
If we subtract 1030 from 1450, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 14:
If we divide 4200 by 515, we get 8 and a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 144718.075728
Subtracting 4120 from 4200 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.

On to step 15:
When dividing 800 by 515, we get 1 with a remainder of 285.
The number 1 becomes the next digit in our result. 
Result so far: 144718.0757281
Deduct 515 from 800 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 16:
2850 divided by 515 is 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 144718.07572815
The remainder is 275 after subtracting 2575 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Our division results in 144718.07572815 with a remaining 2.75e-07.
