637158 ÷ 2 
We want to figure out the number of times 637158 can be divided by 2.

Let's proceed to step 1:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

On to step 2:
2 goes into 3 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 2 from 3 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 2

Going ahead to step 3:
17 divided by 2 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 318.0
Deduct 16 from 17 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Moving on to step 4:
If we divide 11 by 2, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 3185.0
The remainder is 1 after subtracting 10 from 11.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Step 5:
2 goes into 15 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 31857.0
The remainder is 1 after subtracting 14 from 15.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Going ahead to step 6:
When dividing 18 by 2, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 318579.0
If we take 18 away from 18, we end up 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.

Let's proceed to step 7:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 318579.0
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.

Advancing 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: 318579.0
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 318579.0 with a remaining 0.0.
