We're dividing 901381 by 2 
The aim is to understand the frequency of 2 in 901381.

Let's proceed to step 1:
When dividing 9 by 2, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 8 from 9 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Moving on to step 2:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtract 10 from 10 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Moving on to step 3:
If we divide 1 by 2, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 450.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

On to step 4:
2 goes into 13 6 times with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 4506.0
If we take 12 away from 13, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

On to step 5:
2 can be fit into 18 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 45069.0
If we take 18 away from 18, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Advancing to step 6:
1 divided by 2 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 450690.0
Subtracting 0 from 1 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.

Moving on to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 450690.5
If we take 10 away from 10, 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.

Step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 450690.5
If we take 0 away from 0, 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.

Let's proceed to step 9:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 450690.5
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.

The quotient of the division is 450690.5, and the remainder is 0.0.
