We're dividing 917590 by 2 
The aim is to understand the frequency of 2 in 917590.

On to step 1:
If we divide 9 by 2, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 8 from 9 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Let's proceed to step 2:
The number 2 fits into 11 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 10 from 11 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

Going ahead to step 3:
If we divide 17 by 2, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 458.0
Subtract 16 from 17 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

On to step 4:
2 can be fit into 15 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 4587.0
If we take 14 away from 15, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Going ahead to step 5:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 45879.0
If we subtract 18 from 19, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Advancing to step 6:
When dividing 10 by 2, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 458795.0
Deduct 10 from 10 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.

Step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 458795.0
The remainder is 0 after subtracting 0 from 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 8:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 458795.0
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.

The final result is 458795.0 with a remainder of 0.0.
