We divide 355617 by 2
The aim is to understand the frequency of 2 in 355617.

Going ahead to step 1:
When dividing 3 by 2, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 2 from 3 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

On to step 2:
2 goes into 15 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 14 away from 15, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

On to step 3:
2 can be fit into 15 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
If we take 14 away from 15, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 2

Advancing to step 4:
When dividing 16 by 2, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 1778.0
If we subtract 16 from 16, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Step 5:
If we divide 1 by 2, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 17780.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Step 6:
The number 2 fits into 17 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 177808.0
Subtracting 16 from 17 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:
2 can be fit into 10 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 177808.5
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.

On to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 177808.5
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.

Advancing to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 177808.5
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.

The quotient of the division is 177808.5, and the remainder is 0.0.
