Let's divide 677638 by 20
Let's see how many times 20 fits into 677638.

Step 1:
When dividing 6 by 20, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 20

Moving on to step 2:
The number 20 fits into 67 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 7 after subtracting 60 from 67.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 20

Step 3:
When dividing 77 by 20, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 60 away from 77, we end up with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 20

Let's proceed to step 4:
If we divide 176 by 20, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 338.0
Deduct 160 from 176 and we're left with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 20

Advancing to step 5:
The number 20 fits into 163 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 3388.0
If we subtract 160 from 163, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 20

Moving on to step 6:
20 can be fit into 38 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 33881.0
The remainder is 18 after subtracting 20 from 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
20 goes into 180 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 33881.9
The remainder is 0 after subtracting 180 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 33881.9
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.

On to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33881.9
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.

The final result is 33881.9 with a remainder of 0.0.
