We look at the division of 80730099 by 678 
We're looking to find how many times 678 goes into 80730099.

Advancing to step 1:
678 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
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 / 678

Advancing to step 2:
The number 678 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 678

Step 3:
678 goes into 807 1 times with a remainder of 129.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 678 from 807, we get 129.
Include the next digit (3) from the dividend after 129, then repeat: 1293 / 678

Moving on to step 4:
678 goes into 1293 1 times with a remainder of 615.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 678 from 1293, we get 615.
Fetch the next digit (0) from the dividend, attach it to 615 and continue: 6150 / 678

Step 5:
678 can be fit into 6150 9 times, resulting in a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Subtracting 6102 from 6150 leaves us with 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 678

Let's proceed to step 6:
If we divide 480 by 678, we get 0 and a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 1190.0
If we subtract 0 from 480, we get 480.
Append the next digit (9) from the dividend to 480 and continue with: 4809 / 678

Step 7:
If we divide 4809 by 678, we get 7 and a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 11907.0
Subtracting 4746 from 4809 leaves us with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 678

On to step 8:
678 can be fit into 639 0 times, resulting in a remainder of 639.
Record the quotient 0 as the next digit in the result. 
Result so far: 119070.0
Subtract 0 from 639 to get 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

On to step 9:
The number 678 fits into 6390 9 times, leaving a remainder of 288.
Use 9 as the next digit of our solution. 
Result so far: 119070.9
Subtract 6102 from 6390 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 10:
2880 divided by 678 is 4 with a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 119070.94
Subtracting 2712 from 2880 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 11:
678 can be fit into 1680 2 times, resulting in a remainder of 324.
Record the quotient 2 as the next digit in the result. 
Result so far: 119070.942
Subtracting 1356 from 1680 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 12:
If we divide 3240 by 678, we get 4 and a remainder of 528.
The next digit of our result is 4. 
Result so far: 119070.9424
Subtract 2712 from 3240 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 13:
678 can be fit into 5280 7 times, resulting in a remainder of 534.
Use 7 as the next digit of our solution. 
Result so far: 119070.94247
If we subtract 4746 from 5280, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Moving on to step 14:
If we divide 5340 by 678, we get 7 and a remainder of 594.
The next digit of our result is 7. 
Result so far: 119070.942477
Subtracting 4746 from 5340 leaves us with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

The final result is 119070.942477 with a remainder of 5.94e-05.
