42776173 divided by 2 
The aim is to understand the frequency of 2 in 42776173.

Moving on to step 1:
The number 2 fits into 4 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 4 from 4, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Step 2:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 2 from 2 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 2

On to step 3:
2 can be fit into 7 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
If we subtract 6 from 7, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 2

Moving on to step 4:
17 divided by 2 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 2138.0
If we subtract 16 from 17, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Let's proceed to step 5:
2 goes into 16 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 21388.0
If we take 16 away from 16, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Going ahead to step 6:
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: 213880.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

Moving on to step 7:
17 divided by 2 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 2138808.0
Subtracting 16 from 17 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 2

Advancing to step 8:
When dividing 13 by 2, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 21388086.0
Deduct 12 from 13 and we're left 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 9:
2 goes into 10 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 21388086.5
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.

Going ahead to step 10:
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: 21388086.5
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.

On to step 11:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21388086.5
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 21388086.5, with a leftover of 0.0.
