Let's divide 233409 by 53
The aim is to understand the frequency of 53 in 233409.

Advancing to step 1:
The number 53 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 53

Step 2:
23 divided by 53 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 53

Going ahead to step 3:
The number 53 fits into 233 4 times, leaving a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 21 after subtracting 212 from 233.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 53

Going ahead to step 4:
When dividing 214 by 53, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 44.0
The remainder is 2 after subtracting 212 from 214.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 53

Step 5:
If we divide 20 by 53, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 440.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 53

Advancing to step 6:
53 can be fit into 209 3 times, resulting in a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 4403.0
Deduct 159 from 209 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
500 divided by 53 is 9 with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 4403.9
Deduct 477 from 500 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 8:
53 can be fit into 230 4 times, resulting in a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 4403.94
If we subtract 212 from 230, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
180 divided by 53 is 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 4403.943
Subtracting 159 from 180 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 10:
If we divide 210 by 53, we get 3 and a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 4403.9433
Subtracting 159 from 210 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 4403.9433 and a remainder of 0.00051.
