Let's divide 71020316 by 2
The aim is to understand the frequency of 2 in 71020316.

Step 1:
2 goes into 7 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 6 from 7 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Let's proceed to step 2:
2 can be fit into 11 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 35.0
Subtracting 10 from 11 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Step 3:
10 divided by 2 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 355.0
If we subtract 10 from 10, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Advancing to step 4:
When dividing 2 by 2, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 3551.0
If we subtract 2 from 2, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Let's proceed to step 5:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35510.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

On to step 6:
If we divide 3 by 2, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 355101.0
Subtract 2 from 3 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Moving on to step 7:
If we divide 11 by 2, we get 5 and a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 3551015.0
Deduct 10 from 11 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 2

Moving on to step 8:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 35510158.0
Subtract 16 from 16 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.

On to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35510158.0
The remainder is 0 after subtracting 0 from 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 10:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 35510158.0
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 quotient of the division is 35510158.0, and the remainder is 0.0.
