615617 ÷ 2 
The aim is to understand the frequency of 2 in 615617.

On to step 1:
2 goes into 6 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 6 from 6, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

On to step 2:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 30.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Step 3:
When dividing 15 by 2, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 307.0
If we take 14 away from 15, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

On to step 4:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 3078.0
If we subtract 16 from 16, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

On to step 5:
When dividing 1 by 2, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 30780.0
If we subtract 0 from 1, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Advancing to step 6:
The number 2 fits into 17 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 307808.0
Subtract 16 from 17 to get 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:
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: 307808.5
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.

Moving on to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 307808.5
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.

Going ahead to step 9:
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: 307808.5
Subtracting 0 from 0 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.

The final outcome is 307808.5, with a leftover of 0.0.
