Let's divide 915781 by 4
Our goal is to divide 915781 by 4.

Step 1:
4 can be fit into 9 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 8 from 9 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 4

Let's proceed to step 2:
If we divide 11 by 4, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 8 from 11, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 4

On to step 3:
4 goes into 35 8 times with a remainder of 3.
The next digit of our result is 8. 
Result so far: 228.0
The remainder is 3 after subtracting 32 from 35.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 4

Let's proceed to step 4:
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: 2289.0
Subtracting 36 from 37 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 4

Going ahead to step 5:
4 goes into 18 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 22894.0
If we subtract 16 from 18, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 4

Moving on to step 6:
If we divide 21 by 4, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 228945.0
If we take 20 away from 21, we end up 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: 228945.2
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.

Advancing to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 228945.25
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.

Advancing to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 228945.25
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.

Let's proceed to step 10:
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: 228945.25
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 228945.25, and the remainder is 0.0.
