We divide 749415 by 2
The aim is to understand the frequency of 2 in 749415.

On to step 1:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 1 after subtracting 6 from 7.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 2

Going ahead to step 2:
2 can be fit into 14 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 37.0
The remainder is 0 after subtracting 14 from 14.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

On to step 3:
9 divided by 2 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 374.0
If we subtract 8 from 9, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Advancing to step 4:
If we divide 14 by 2, we get 7 and a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 3747.0
Deduct 14 from 14 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Going ahead to step 5:
When dividing 1 by 2, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 37470.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Going ahead to step 6:
The number 2 fits into 15 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 374707.0
Subtracting 14 from 15 leaves us 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.

Going ahead to step 7:
10 divided by 2 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 374707.5
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:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 374707.5
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.

Step 9:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 374707.5
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.

The final outcome is 374707.5, with a leftover of 0.0.
