Let's divide 381721 by 4
We're looking to find how many times 4 goes into 381721.

Advancing to step 1:
When dividing 3 by 4, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 4

On to step 2:
38 divided by 4 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 36 from 38 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 4

On to step 3:
21 divided by 4 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtract 20 from 21 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 4

Moving on to step 4:
4 goes into 17 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 954.0
Subtract 16 from 17 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 4

Step 5:
4 goes into 12 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 9543.0
Deduct 12 from 12 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 4

Going ahead to step 6:
The number 4 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 95430.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
4 can be fit into 10 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 95430.2
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.

Going ahead to step 8:
20 divided by 4 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 95430.25
If we take 20 away from 20, 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:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 95430.25
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.

Moving on to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 95430.25
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.

Our division results in 95430.25 with a remaining 0.0.
