We divide 20673 by 4
Let's see how many times 4 fits into 20673.

On to step 1:
If we divide 2 by 4, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 4

Advancing to step 2:
20 divided by 4 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 20 away from 20, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 4

Moving on to step 3:
The number 4 fits into 6 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we subtract 4 from 6, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 4

Going ahead to step 4:
4 goes into 27 6 times with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 516.0
If we take 24 away from 27, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 4

Going ahead to step 5:
4 can be fit into 33 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 5168.0
Deduct 32 from 33 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 6:
If we divide 10 by 4, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 5168.2
Deduct 8 from 10 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5168.25
Deduct 20 from 20 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.

Advancing to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5168.25
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.

Let's proceed to step 9:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5168.25
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.

The quotient of the division is 5168.25, and the remainder is 0.0.
