We're dividing 386486 by 1 
We want to figure out the number of times 386486 can be divided by 1.

On to step 1:
If we divide 3 by 1, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 3 from 3, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Going ahead to step 2:
If we divide 8 by 1, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we take 8 away from 8, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Let's proceed to step 3:
6 divided by 1 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 386.0
Subtracting 6 from 6 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

On to step 4:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 3864.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Let's proceed to step 5:
1 goes into 8 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 38648.0
Subtract 8 from 8 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Going ahead to step 6:
If we divide 6 by 1, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 386486.0
Subtracting 6 from 6 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 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 386486.0
Subtract 0 from 0 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 8:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 386486.0
If we subtract 0 from 0, we 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.

The final outcome is 386486.0, with a leftover of 0.0.
