We divide 80349955 by 515
Our goal is to divide 80349955 by 515.

On to step 1:
When dividing 8 by 515, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 515

Going ahead to step 2:
If we divide 80 by 515, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 515

Advancing to step 3:
If we divide 803 by 515, we get 1 and a remainder of 288.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 288 after subtracting 515 from 803.
Append the next digit (4) from the dividend to 288 and continue with: 2884 / 515

On to step 4:
When dividing 2884 by 515, we get 5 with a remainder of 309.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 2575 from 2884, we get 309.
Bring next digit (9) of the dividend behind the 309 and repeat the process: 3099 / 515

Let's proceed to step 5:
515 can be fit into 3099 6 times, resulting in a remainder of 9.
The next digit of our result is 6. 
Result so far: 156.0
If we subtract 3090 from 3099, we get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 515

Step 6:
515 goes into 99 0 times with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 1560.0
If we subtract 0 from 99, we get 99.
Include the next digit (5) from the dividend after 99, then repeat: 995 / 515

Going ahead to step 7:
When dividing 995 by 515, we get 1 with a remainder of 480.
Record the quotient 1 as the next digit in the result. 
Result so far: 15601.0
If we subtract 515 from 995, we get 480.
Bring next digit (5) of the dividend behind the 480 and repeat the process: 4805 / 515

Going ahead to step 8:
The number 515 fits into 4805 9 times, leaving a remainder of 170.
Write down 9 as next digit of the result. 
Result so far: 156019.0
Subtract 4635 from 4805 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 9:
515 goes into 1700 3 times with a remainder of 155.
Record the quotient 3 as the next digit in the result. 
Result so far: 156019.3
If we subtract 1545 from 1700, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 10:
515 goes into 1550 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 156019.33
Deduct 1545 from 1550 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 156019.33, with a leftover of 0.005.
