We look at the division of 237335 by 7 
The aim is to understand the frequency of 7 in 237335.

Let's proceed to step 1:
7 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 7

Going ahead to step 2:
If we divide 23 by 7, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 21 from 23 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 7

Going ahead to step 3:
When dividing 27 by 7, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Deduct 21 from 27 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 7

On to step 4:
7 goes into 63 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 339.0
If we subtract 63 from 63, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 7

Step 5:
7 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 3390.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 7

Going ahead to step 6:
35 divided by 7 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 33905.0
Subtracting 35 from 35 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.

Let's proceed to step 7:
0 divided by 7 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33905.0
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.

Going ahead to step 8:
When dividing 0 by 7, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 33905.0
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.

The final result is 33905.0 with a remainder of 0.0.
