843965 divided by 4 
We want to figure out the number of times 843965 can be divided by 4.

Step 1:
4 can be fit into 8 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 8 away from 8, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 4

On to step 2:
4 can be fit into 4 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 0 after subtracting 4 from 4.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 4

On to step 3:
4 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 4

Let's proceed to step 4:
The number 4 fits into 39 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 2109.0
If we subtract 36 from 39, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 4

Let's proceed to step 5:
4 goes into 36 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 21099.0
The remainder is 0 after subtracting 36 from 36.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 4

Advancing to step 6:
If we divide 5 by 4, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 210991.0
The remainder is 1 after subtracting 4 from 5.
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:
10 divided by 4 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 210991.2
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.

Let's proceed to step 8:
4 goes into 20 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 210991.25
Subtracting 20 from 20 leaves us 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:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 210991.25
Subtracting 0 from 0 leaves us 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:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 210991.25
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 210991.25 and a remainder of 0.0.
