555601 ÷ 2 
The aim is to understand the frequency of 2 in 555601.

On to step 1:
If we divide 5 by 2, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 4 from 5 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Going ahead to step 2:
When dividing 15 by 2, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we subtract 14 from 15, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Moving on to step 3:
If we divide 15 by 2, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 277.0
Subtract 14 from 15 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Advancing to step 4:
If we divide 16 by 2, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 2778.0
Subtracting 16 from 16 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Advancing to step 5:
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: 27780.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Moving on to step 6:
If we divide 1 by 2, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 277800.0
If we take 0 away from 1, we end up 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.

Advancing to step 7:
2 goes into 10 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 277800.5
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.

On to step 8:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 277800.5
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.

Advancing to step 9:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 277800.5
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.

Our division results in 277800.5 with a remaining 0.0.
