80996934 divided by 678 
Our goal is to divide 80996934 by 678.

Step 1:
8 divided by 678 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 678

Advancing to step 2:
80 divided by 678 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 678

Advancing to step 3:
678 goes into 809 1 times with a remainder of 131.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 131 after subtracting 678 from 809.
Fetch the next digit (9) from the dividend, attach it to 131 and continue: 1319 / 678

Let's proceed to step 4:
678 can be fit into 1319 1 times, resulting in a remainder of 641.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 678 from 1319 leaves us with 641.
Grab the next digit (6) from the dividend, add it to 641, then carry on: 6416 / 678

Going ahead to step 5:
If we divide 6416 by 678, we get 9 and a remainder of 314.
Write down 9 as next digit of the result. 
Result so far: 119.0
Deduct 6102 from 6416 and we're left with 314.
Include the next digit (9) from the dividend after 314, then repeat: 3149 / 678

On to step 6:
3149 divided by 678 is 4 with a remainder of 437.
Put 4 as the next digit of the answer. 
Result so far: 1194.0
Subtract 2712 from 3149 to get 437.
Take the next digit (3) from the dividend and append it to 437, then repeat: 4373 / 678

Going ahead to step 7:
4373 divided by 678 is 6 with a remainder of 305.
Record the quotient 6 as the next digit in the result. 
Result so far: 11946.0
The remainder is 305 after subtracting 4068 from 4373.
Fetch the next digit (4) from the dividend, attach it to 305 and continue: 3054 / 678

Let's proceed to step 8:
3054 divided by 678 is 4 with a remainder of 342.
The next digit of our result is 4. 
Result so far: 119464.0
Subtracting 2712 from 3054 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 9:
678 goes into 3420 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 119464.5
Subtracting 3390 from 3420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
678 goes into 300 0 times with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 119464.5
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
When dividing 3000 by 678, we get 4 with a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 119464.504
Subtract 2712 from 3000 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.

Moving on to step 12:
2880 divided by 678 is 4 with a remainder of 168.
The next digit of our result is 4. 
Result so far: 119464.5044
If we subtract 2712 from 2880, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 119464.5044 with a remainder of 0.00168.
