Let's divide 237617 by 2
The aim is to understand the frequency of 2 in 237617.

Step 1:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 2 from 2.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

On to step 2:
The number 2 fits into 3 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 2 from 3 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

Let's proceed to step 3:
When dividing 17 by 2, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Deduct 16 from 17 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Moving on to step 4:
2 goes into 16 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1188.0
Subtracting 16 from 16 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Let's proceed to step 5:
1 divided by 2 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 11880.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 2

Advancing to step 6:
2 goes into 17 8 times with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 118808.0
If we subtract 16 from 17, we get 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:
2 goes into 10 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 118808.5
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.

Let's proceed to step 8:
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: 118808.5
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.

Moving on to step 9:
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: 118808.5
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.

Our division results in 118808.5 with a remaining 0.0.
