We divide 683994 by 20
We're looking to find how many times 20 goes into 683994.

Advancing to step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 20

Step 2:
The number 20 fits into 68 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 60 from 68 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 20

Moving on to step 3:
83 divided by 20 is 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we take 80 away from 83, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 20

On to step 4:
The number 20 fits into 39 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 341.0
Subtracting 20 from 39 leaves us with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 20

Let's proceed to step 5:
199 divided by 20 is 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 3419.0
If we take 180 away from 199, we end up with 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 20

Moving on to step 6:
20 can be fit into 194 9 times, resulting in a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 34199.0
If we subtract 180 from 194, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
20 can be fit into 140 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 34199.7
Subtracting 140 from 140 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 8:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 34199.7
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 9:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34199.7
If we subtract 0 from 0, we 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.

After the division, we end up with 34199.7 and a remainder of 0.0.
