We divide 80314425 by 515
Our goal is to divide 80314425 by 515.

On to step 1:
The number 515 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 515

Advancing to step 2:
80 divided by 515 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 515

On to step 3:
If we divide 803 by 515, we get 1 and a remainder of 288.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 515 from 803 to get 288.
Append the next digit (1) from the dividend to 288 and continue with: 2881 / 515

Let's proceed to step 4:
2881 divided by 515 is 5 with a remainder of 306.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 2575 from 2881 to get 306.
Grab the next digit (4) from the dividend, add it to 306, then carry on: 3064 / 515

Advancing to step 5:
515 goes into 3064 5 times with a remainder of 489.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
Subtract 2575 from 3064 to get 489.
Take the next digit (4) from the dividend and append it to 489, then repeat: 4894 / 515

On to step 6:
If we divide 4894 by 515, we get 9 and a remainder of 259.
The number 9 becomes the next digit in our result. 
Result so far: 1559.0
Deduct 4635 from 4894 and we're left with 259.
Fetch the next digit (2) from the dividend, attach it to 259 and continue: 2592 / 515

Moving on to step 7:
The number 515 fits into 2592 5 times, leaving a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 15595.0
The remainder is 17 after subtracting 2575 from 2592.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 515

Going ahead to step 8:
If we divide 175 by 515, we get 0 and a remainder of 175.
The next digit of our result is 0. 
Result so far: 155950.0
If we subtract 0 from 175, we 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.

Moving on to step 9:
The number 515 fits into 1750 3 times, leaving a remainder of 205.
Use 3 as the next digit of our solution. 
Result so far: 155950.3
The remainder is 205 after subtracting 1545 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 10:
515 goes into 2050 3 times with a remainder of 505.
The next digit of our result is 3. 
Result so far: 155950.33
Deduct 1545 from 2050 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

The final result is 155950.33 with a remainder of 0.505.
