Let's divide 82160915 by 515
We want to figure out the number of times 82160915 can be divided by 515.

On to step 1:
8 divided by 515 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 515

Going ahead to step 2:
The number 515 fits into 82 0 times, leaving a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Grab the next digit (1) from the dividend, add it to 82, then carry on: 821 / 515

Let's proceed to step 3:
821 divided by 515 is 1 with a remainder of 306.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 515 away from 821, we end up with 306.
Bring next digit (6) of the dividend behind the 306 and repeat the process: 3066 / 515

Going ahead to step 4:
When dividing 3066 by 515, we get 5 with a remainder of 491.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 2575 from 3066, we get 491.
Take the next digit (0) from the dividend and append it to 491, then repeat: 4910 / 515

Advancing to step 5:
When dividing 4910 by 515, we get 9 with a remainder of 275.
Put 9 as the next digit of the answer. 
Result so far: 159.0
If we subtract 4635 from 4910, we get 275.
Fetch the next digit (9) from the dividend, attach it to 275 and continue: 2759 / 515

Let's proceed to step 6:
If we divide 2759 by 515, we get 5 and a remainder of 184.
The next digit of our result is 5. 
Result so far: 1595.0
The remainder is 184 after subtracting 2575 from 2759.
Take the next digit (1) from the dividend and append it to 184, then repeat: 1841 / 515

On to step 7:
When dividing 1841 by 515, we get 3 with a remainder of 296.
The next digit of our result is 3. 
Result so far: 15953.0
Deduct 1545 from 1841 and we're left with 296.
Bring next digit (5) of the dividend behind the 296 and repeat the process: 2965 / 515

Going ahead to step 8:
2965 divided by 515 is 5 with a remainder of 390.
Use 5 as the next digit of our solution. 
Result so far: 159535.0
If we subtract 2575 from 2965, we get 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 9:
When dividing 3900 by 515, we get 7 with a remainder of 295.
Record the quotient 7 as the next digit in the result. 
Result so far: 159535.7
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 10:
The number 515 fits into 2950 5 times, leaving a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 159535.75
If we subtract 2575 from 2950, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 11:
If we divide 3750 by 515, we get 7 and a remainder of 145.
The number 7 becomes the next digit in our result. 
Result so far: 159535.757
If we take 3605 away from 3750, we end up with 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 12:
If we divide 1450 by 515, we get 2 and a remainder of 420.
The next digit of our result is 2. 
Result so far: 159535.7572
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.

Let's proceed to step 13:
If we divide 4200 by 515, we get 8 and a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 159535.75728
The remainder is 80 after subtracting 4120 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
800 divided by 515 is 1 with a remainder of 285.
The number 1 becomes the next digit in our result. 
Result so far: 159535.757281
Subtract 515 from 800 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 15:
When dividing 2850 by 515, we get 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 159535.7572815
Deduct 2575 from 2850 and we're left 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.

Step 16:
When dividing 2750 by 515, we get 5 with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 159535.75728155
Deduct 2575 from 2750 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The quotient of the division is 159535.75728155, and the remainder is 1.75e-07.
