We're dividing 642683 by 20 
We're looking to find how many times 20 goes into 642683.

On to step 1:
When dividing 6 by 20, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 20

Let's proceed to step 2:
64 divided by 20 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 60 from 64, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 20

Step 3:
20 can be fit into 42 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 32.0
The remainder is 2 after subtracting 40 from 42.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 20

Advancing to step 4:
20 goes into 26 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 321.0
Subtracting 20 from 26 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 20

Let's proceed to step 5:
20 can be fit into 68 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 3213.0
If we subtract 60 from 68, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 20

Step 6:
20 goes into 83 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 32134.0
If we take 80 away from 83, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
20 can be fit into 30 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 32134.1
Subtracting 20 from 30 leaves us 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.

Let's proceed to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 32134.15
If we subtract 100 from 100, 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.

Going ahead to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 32134.15
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.

Let's proceed to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 32134.15
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 quotient of the division is 32134.15, and the remainder is 0.0.
