We're dividing 678357 by 80 
We want to figure out the number of times 678357 can be divided by 80.

Step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 80

Step 2:
80 can be fit into 67 0 times, resulting in a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Fetch the next digit (8) from the dividend, attach it to 67 and continue: 678 / 80

Let's proceed to step 3:
When dividing 678 by 80, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 640 from 678, we get 38.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 80

Advancing to step 4:
383 divided by 80 is 4 with a remainder of 63.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtracting 320 from 383 leaves us with 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 80

Step 5:
80 goes into 635 7 times with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 847.0
Subtracting 560 from 635 leaves us with 75.
Take the next digit (7) from the dividend and append it to 75, then repeat: 757 / 80

Going ahead to step 6:
If we divide 757 by 80, we get 9 and a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 8479.0
If we take 720 away from 757, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
If we divide 370 by 80, we get 4 and a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 8479.4
If we take 320 away from 370, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
If we divide 500 by 80, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 8479.46
Subtracting 480 from 500 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 8479.462
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 8479.4625
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8479.4625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8479.4625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 8479.4625 with a remainder of 0.0.
