Let's divide 80634320 by 515
Our goal is to divide 80634320 by 515.

Going ahead to step 1:
The number 515 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 515

Going ahead to step 2:
515 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 515

Advancing to step 3:
If we divide 806 by 515, we get 1 and a remainder of 291.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 515 from 806, we get 291.
Include the next digit (3) from the dividend after 291, then repeat: 2913 / 515

Going ahead to step 4:
The number 515 fits into 2913 5 times, leaving a remainder of 338.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 2575 from 2913, we get 338.
Grab the next digit (4) from the dividend, add it to 338, then carry on: 3384 / 515

On to step 5:
515 can be fit into 3384 6 times, resulting in a remainder of 294.
Write down 6 as next digit of the result. 
Result so far: 156.0
If we take 3090 away from 3384, we end up with 294.
Fetch the next digit (3) from the dividend, attach it to 294 and continue: 2943 / 515

Going ahead to step 6:
The number 515 fits into 2943 5 times, leaving a remainder of 368.
Put 5 as the next digit of the answer. 
Result so far: 1565.0
If we take 2575 away from 2943, we end up with 368.
Grab the next digit (2) from the dividend, add it to 368, then carry on: 3682 / 515

Going ahead to step 7:
3682 divided by 515 is 7 with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 15657.0
If we take 3605 away from 3682, we end up with 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 515

Let's proceed to step 8:
515 goes into 770 1 times with a remainder of 255.
Use 1 as the next digit of our solution. 
Result so far: 156571.0
If we take 515 away from 770, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 9:
If we divide 2550 by 515, we get 4 and a remainder of 490.
Use 4 as the next digit of our solution. 
Result so far: 156571.4
If we subtract 2060 from 2550, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 10:
When dividing 4900 by 515, we get 9 with a remainder of 265.
The number 9 becomes the next digit in our result. 
Result so far: 156571.49
If we take 4635 away from 4900, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 11:
When dividing 2650 by 515, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 156571.495
If we subtract 2575 from 2650, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 12:
When dividing 750 by 515, we get 1 with a remainder of 235.
The next digit of our result is 1. 
Result so far: 156571.4951
The remainder is 235 after subtracting 515 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 13:
When dividing 2350 by 515, we get 4 with a remainder of 290.
The next digit of our result is 4. 
Result so far: 156571.49514
If we subtract 2060 from 2350, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
2900 divided by 515 is 5 with a remainder of 325.
The next digit of our result is 5. 
Result so far: 156571.495145
The remainder is 325 after subtracting 2575 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 15:
3250 divided by 515 is 6 with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 156571.4951456
Deduct 3090 from 3250 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 16:
If we divide 1600 by 515, we get 3 and a remainder of 55.
The next digit of our result is 3. 
Result so far: 156571.49514563
The remainder is 55 after subtracting 1545 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 156571.49514563, and the remainder is 5.5e-08.
