We look at the division of 371603 by 2 
We want to figure out the number of times 371603 can be divided by 2.

Going ahead to step 1:
2 can be fit into 3 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 2 from 3 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

On to step 2:
2 goes into 17 8 times with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 1 after subtracting 16 from 17.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Let's proceed to step 3:
11 divided by 2 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 185.0
Deduct 10 from 11 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

On to step 4:
If we divide 16 by 2, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 1858.0
If we subtract 16 from 16, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Let's proceed to step 5:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18580.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Moving on to step 6:
When dividing 3 by 2, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 185801.0
If we take 2 away from 3, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 185801.5
Subtracting 10 from 10 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.

Going ahead to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 185801.5
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.

Going ahead to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 185801.5
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.

Our division results in 185801.5 with a remaining 0.0.
