678946 ÷ 5 
We're looking to find how many times 5 goes into 678946.

On to step 1:
6 divided by 5 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 5 away from 6, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 5

Step 2:
When dividing 17 by 5, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 2 after subtracting 15 from 17.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 5

Going ahead to step 3:
5 goes into 28 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 135.0
Subtracting 25 from 28 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 5

Going ahead to step 4:
5 can be fit into 39 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 1357.0
If we subtract 35 from 39, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 5

Going ahead to step 5:
44 divided by 5 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 13578.0
Subtracting 40 from 44 leaves us with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 5

Moving on to step 6:
When dividing 46 by 5, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 135789.0
If we subtract 45 from 46, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 5, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 135789.2
Subtracting 10 from 10 leaves us 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.

Advancing to step 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 135789.2
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 9:
When dividing 0 by 5, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 135789.2
Subtract 0 from 0 to 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 outcome is 135789.2, with a leftover of 0.0.
