746643 divided by 2 
The aim is to understand the frequency of 2 in 746643.

Let's proceed to step 1:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 6 from 7, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Let's proceed to step 2:
If we divide 14 by 2, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 14 from 14 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

On to step 3:
When dividing 6 by 2, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 373.0
Subtract 6 from 6 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Step 4:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3733.0
The remainder is 0 after subtracting 6 from 6.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

On to step 5:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 37332.0
Subtracting 4 from 4 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

On to step 6:
The number 2 fits into 3 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 373321.0
Subtracting 2 from 3 leaves us 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 7:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 373321.5
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.

Let's proceed to step 8:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 373321.5
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.

Advancing to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 373321.5
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.

After the division, we end up with 373321.5 and a remainder of 0.0.
