Let's divide 309575 by 4
Our goal is to divide 309575 by 4.

Step 1:
4 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 4

Step 2:
When dividing 30 by 4, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 2 after subtracting 28 from 30.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 4

Let's proceed to step 3:
The number 4 fits into 29 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Deduct 28 from 29 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 4

Step 4:
15 divided by 4 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 773.0
If we subtract 12 from 15, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 4

Moving on to step 5:
4 can be fit into 37 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 7739.0
If we take 36 away from 37, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 4

Moving on to step 6:
4 can be fit into 15 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 77393.0
Subtracting 12 from 15 leaves us 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.

Moving on to step 7:
When dividing 30 by 4, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 77393.7
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed 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: 77393.75
Subtract 20 from 20 to 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.

Step 9:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 77393.75
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.

Let's proceed to step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 77393.75
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.

After the division, we end up with 77393.75 and a remainder of 0.0.
