We look at the division of 678637 by 20 
Let's see how many times 20 fits into 678637.

Moving on to step 1:
20 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 20

Moving on to step 2:
67 divided by 20 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 60 from 67, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 20

Going ahead to step 3:
The number 20 fits into 78 3 times, leaving a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 60 from 78, we get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 20

Let's proceed to step 4:
The number 20 fits into 186 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 339.0
Deduct 180 from 186 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 20

Advancing to step 5:
If we divide 63 by 20, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 3393.0
If we subtract 60 from 63, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 20

Advancing to step 6:
If we divide 37 by 20, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 33931.0
If we subtract 20 from 37, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
If we divide 170 by 20, we get 8 and a remainder of 10.
The next digit of our result is 8. 
Result so far: 33931.8
If we take 160 away from 170, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 33931.85
The remainder is 0 after subtracting 100 from 100.
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 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33931.85
If we take 0 away from 0, we end up 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.

Moving on to step 10:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33931.85
The remainder is 0 after subtracting 0 from 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 quotient of the division is 33931.85, and the remainder is 0.0.
