We divide 357086 by 2
We want to figure out the number of times 357086 can be divided by 2.

Step 1:
2 goes into 3 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 2 from 3 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Advancing to step 2:
15 divided by 2 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 14 away from 15, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 2

Let's proceed to step 3:
When dividing 17 by 2, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 178.0
Subtract 16 from 17 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Step 4:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1785.0
Subtract 10 from 10 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Moving on to step 5:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 17854.0
If we subtract 8 from 8, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Advancing to step 6:
When dividing 6 by 2, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 178543.0
If we subtract 6 from 6, 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.

On to step 7:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 178543.0
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.

Let's proceed to step 8:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 178543.0
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.

After the division, we end up with 178543.0 and a remainder of 0.0.
