We divide 86245 by 2
Let's see how many times 2 fits into 86245.

Let's proceed to step 1:
8 divided by 2 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Step 2:
6 divided by 2 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 6 from 6, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Let's proceed to step 3:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 431.0
If we subtract 2 from 2, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Going ahead to step 4:
2 goes into 4 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 4312.0
If we take 4 away from 4, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Step 5:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 43122.0
If we subtract 4 from 5, we get 1.
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 6:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 43122.5
Subtract 10 from 10 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.

Let's proceed to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43122.5
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.

Moving on to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 43122.5
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 43122.5, with a leftover of 0.0.
