We divide 61543584 by 2
The aim is to understand the frequency of 2 in 61543584.

Advancing to step 1:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 6 from 6 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

On to step 2:
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: 30.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Going ahead to step 3:
2 goes into 15 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 307.0
Subtract 14 from 15 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 2

Step 4:
If we divide 14 by 2, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 3077.0
Subtract 14 from 14 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Step 5:
2 goes into 3 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 30771.0
If we subtract 2 from 3, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Advancing to step 6:
15 divided by 2 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 307717.0
If we subtract 14 from 15, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Advancing to step 7:
If we divide 18 by 2, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 3077179.0
If we subtract 18 from 18, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 2

On to step 8:
The number 2 fits into 4 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 30771792.0
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.

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: 30771792.0
Subtract 0 from 0 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.

Step 10:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30771792.0
Subtract 0 from 0 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.

The quotient of the division is 30771792.0, and the remainder is 0.0.
