Let's divide 915225 by 2
We want to figure out the number of times 915225 can be divided by 2.

On to step 1:
If we divide 9 by 2, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 8 from 9, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Moving on to step 2:
2 goes into 11 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 45.0
Deduct 10 from 11 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

On to step 3:
15 divided by 2 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 457.0
Subtracting 14 from 15 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

On to step 4:
2 goes into 12 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 4576.0
Subtracting 12 from 12 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

On to step 5:
2 goes into 2 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 45761.0
Subtracting 2 from 2 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Advancing to step 6:
2 goes into 5 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 457612.0
The remainder is 1 after subtracting 4 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 457612.5
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.

Moving on to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 457612.5
If we take 0 away from 0, 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.

Going ahead to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 457612.5
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.

After the division, we end up with 457612.5 and a remainder of 0.0.
