52353931 ÷ 158 
The aim is to understand the frequency of 158 in 52353931.

On to step 1:
When dividing 5 by 158, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 158

Advancing to step 2:
52 divided by 158 is 0 with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Include the next digit (3) from the dividend after 52, then repeat: 523 / 158

Step 3:
158 can be fit into 523 3 times, resulting in a remainder of 49.
The next digit of our result is 3. 
Result so far: 3.0
If we take 474 away from 523, we end up with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 158

Step 4:
158 goes into 495 3 times with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 474 from 495, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 158

Let's proceed to step 5:
When dividing 213 by 158, we get 1 with a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 331.0
Deduct 158 from 213 and we're left with 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 158

On to step 6:
559 divided by 158 is 3 with a remainder of 85.
The next digit of our result is 3. 
Result so far: 3313.0
The remainder is 85 after subtracting 474 from 559.
Include the next digit (3) from the dividend after 85, then repeat: 853 / 158

Going ahead to step 7:
158 can be fit into 853 5 times, resulting in a remainder of 63.
Put 5 as the next digit of the answer. 
Result so far: 33135.0
The remainder is 63 after subtracting 790 from 853.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 158

Advancing to step 8:
If we divide 631 by 158, we get 3 and a remainder of 157.
Use 3 as the next digit of our solution. 
Result so far: 331353.0
If we subtract 474 from 631, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 9:
158 goes into 1570 9 times with a remainder of 148.
Use 9 as the next digit of our solution. 
Result so far: 331353.9
If we take 1422 away from 1570, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 10:
When dividing 1480 by 158, we get 9 with a remainder of 58.
The next digit of our result is 9. 
Result so far: 331353.99
The remainder is 58 after subtracting 1422 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final result is 331353.99 with a remainder of 0.058.
