We look at the division of 53234281 by 258 
The aim is to understand the frequency of 258 in 53234281.

Moving on to step 1:
5 divided by 258 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 258

Step 2:
53 divided by 258 is 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 258

Let's proceed to step 3:
258 goes into 532 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 516 away from 532, we end up with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 258

Step 4:
258 goes into 163 0 times with a remainder of 163.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 163 leaves us with 163.
Fetch the next digit (4) from the dividend, attach it to 163 and continue: 1634 / 258

On to step 5:
1634 divided by 258 is 6 with a remainder of 86.
The next digit of our result is 6. 
Result so far: 206.0
Deduct 1548 from 1634 and we're left with 86.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 258

Moving on to step 6:
When dividing 862 by 258, we get 3 with a remainder of 88.
The next digit of our result is 3. 
Result so far: 2063.0
Deduct 774 from 862 and we're left with 88.
Append the next digit (8) from the dividend to 88 and continue with: 888 / 258

On to step 7:
The number 258 fits into 888 3 times, leaving a remainder of 114.
Write down 3 as next digit of the result. 
Result so far: 20633.0
The remainder is 114 after subtracting 774 from 888.
Bring next digit (1) of the dividend behind the 114 and repeat the process: 1141 / 258

Advancing to step 8:
When dividing 1141 by 258, we get 4 with a remainder of 109.
The next digit of our result is 4. 
Result so far: 206334.0
If we subtract 1032 from 1141, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 9:
If we divide 1090 by 258, we get 4 and a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 206334.4
If we subtract 1032 from 1090, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
258 can be fit into 580 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 206334.42
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
If we divide 640 by 258, we get 2 and a remainder of 124.
Record the quotient 2 as the next digit in the result. 
Result so far: 206334.422
The remainder is 124 after subtracting 516 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final outcome is 206334.422, with a leftover of 0.0124.
