We divide 678551 by 20
We want to divide 678551 by 20.

Advancing to step 1:
When dividing 6 by 20, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 20

Let's proceed to step 2:
67 divided by 20 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 60 from 67 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 20

On to step 3:
78 divided by 20 is 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 60 from 78 and we're left with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 20

Moving on to step 4:
20 can be fit into 185 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 339.0
The remainder is 5 after subtracting 180 from 185.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 20

Advancing to step 5:
When dividing 55 by 20, we get 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 3392.0
Subtracting 40 from 55 leaves us with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 20

Going ahead to step 6:
The number 20 fits into 151 7 times, leaving a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 33927.0
Subtracting 140 from 151 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 20, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 33927.5
The remainder is 10 after subtracting 100 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 33927.55
Subtract 100 from 100 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 result is 33927.55 with a remainder of 0.0.
