865446 divided by 4 
We're looking to find how many times 4 goes into 865446.

Step 1:
8 divided by 4 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 8 from 8 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 4

On to step 2:
When dividing 6 by 4, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 4 from 6 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 4

Going ahead to step 3:
25 divided by 4 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 216.0
Subtract 24 from 25 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 4

On to step 4:
When dividing 14 by 4, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 2163.0
If we take 12 away from 14, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 4

Step 5:
24 divided by 4 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 21636.0
Subtract 24 from 24 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 4

On to step 6:
When dividing 6 by 4, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 216361.0
Deduct 4 from 6 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 7:
If we divide 20 by 4, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 216361.5
Deduct 20 from 20 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.

Advancing to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 216361.5
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 9:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 216361.5
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.

The final outcome is 216361.5, with a leftover of 0.0.
