Let's divide 638725 by 4
Our goal is to divide 638725 by 4.

Step 1:
The number 4 fits into 6 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 4 from 6, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 4

Moving on to step 2:
If we divide 23 by 4, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 3 after subtracting 20 from 23.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 4

Moving on to step 3:
4 goes into 38 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 159.0
Subtract 36 from 38 to get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 4

On to step 4:
4 can be fit into 27 6 times, resulting in a remainder of 3.
The next digit of our result is 6. 
Result so far: 1596.0
Subtracting 24 from 27 leaves us with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 4

Going ahead to step 5:
4 goes into 32 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 15968.0
Subtracting 32 from 32 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 4

Let's proceed to step 6:
4 can be fit into 5 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 159681.0
Deduct 4 from 5 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 7:
4 goes into 10 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 159681.2
If we take 8 away from 10, we end up 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.

Moving on to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 159681.25
The remainder is 0 after subtracting 20 from 20.
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:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 159681.25
The remainder is 0 after subtracting 0 from 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 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: 159681.25
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 final result is 159681.25 with a remainder of 0.0.
