53356861 ÷ 2 
The aim is to understand the frequency of 2 in 53356861.

Going ahead to step 1:
2 can be fit into 5 2 times, resulting in 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 (3) from the dividend, add it to 1, then carry on: 13 / 2

On to step 2:
The number 2 fits into 13 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 26.0
If we subtract 12 from 13, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Step 3:
If we divide 13 by 2, we get 6 and a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 266.0
Subtracting 12 from 13 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Step 4:
If we divide 15 by 2, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 2667.0
The remainder is 1 after subtracting 14 from 15.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Advancing to step 5:
2 goes into 16 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 26678.0
If we take 16 away from 16, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Let's proceed to step 6:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 266784.0
If we subtract 8 from 8, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Step 7:
When dividing 6 by 2, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 2667843.0
If we subtract 6 from 6, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

On to step 8:
2 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 26678430.0
Deduct 0 from 1 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.

Moving on to step 9:
When dividing 10 by 2, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 26678430.5
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.

Moving on to step 10:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26678430.5
If we subtract 0 from 0, we 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 11:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26678430.5
If we subtract 0 from 0, we 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 26678430.5, and the remainder is 0.0.
