673944 divided by 20 
Let's see how many times 20 fits into 673944.

Let's proceed 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
Subtract 0 from 6 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 20

On to step 2:
67 divided by 20 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 60 from 67, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 20

On to step 3:
73 divided by 20 is 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtracting 60 from 73 leaves us with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 20

On to step 4:
139 divided by 20 is 6 with a remainder of 19.
The next digit of our result is 6. 
Result so far: 336.0
Subtract 120 from 139 to get 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 20

On to step 5:
194 divided by 20 is 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 3369.0
If we subtract 180 from 194, we get 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 20

Going ahead to step 6:
The number 20 fits into 144 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 33697.0
Subtract 140 from 144 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
20 can be fit into 40 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 33697.2
Subtract 40 from 40 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.

Advancing to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33697.2
Deduct 0 from 0 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.

Let's proceed to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33697.2
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.

Our division results in 33697.2 with a remaining 0.0.
