Let's divide 17873 by 4
Let's see how many times 4 fits into 17873.

On to step 1:
The number 4 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 4

Going ahead to step 2:
4 can be fit into 17 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 16 away from 17, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 4

Advancing to step 3:
The number 4 fits into 18 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtracting 16 from 18 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 4

Step 4:
The number 4 fits into 27 6 times, leaving a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 446.0
If we subtract 24 from 27, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 4

Step 5:
33 divided by 4 is 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 4468.0
The remainder is 1 after subtracting 32 from 33.
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.
The next digit of our result is 2. 
Result so far: 4468.2
The remainder is 2 after subtracting 8 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
4 goes into 20 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 4468.25
If we subtract 20 from 20, 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.

On to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4468.25
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.

Advancing to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4468.25
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.

The quotient of the division is 4468.25, and the remainder is 0.0.
