690904 divided by 2 
The aim is to understand the frequency of 2 in 690904.

On to step 1:
2 goes into 6 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 6 from 6 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Moving on to step 2:
2 goes into 9 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Deduct 8 from 9 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

On to step 3:
When dividing 10 by 2, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 345.0
Subtract 10 from 10 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

On to step 4:
When dividing 9 by 2, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 3454.0
Subtracting 8 from 9 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Advancing to step 5:
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: 34545.0
If we subtract 10 from 10, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Moving on to step 6:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 345452.0
If we take 4 away from 4, 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.

Step 7:
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: 345452.0
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.

On to step 8:
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: 345452.0
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.

The final result is 345452.0 with a remainder of 0.0.
