27158229 divided by 858 
The aim is to understand the frequency of 858 in 27158229.

Let's proceed to step 1:
When dividing 2 by 858, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 858

On to step 2:
858 can be fit into 27 0 times, resulting in a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 858

Let's proceed to step 3:
271 divided by 858 is 0 with a remainder of 271.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 271, we end up with 271.
Include the next digit (5) from the dividend after 271, then repeat: 2715 / 858

Advancing to step 4:
858 can be fit into 2715 3 times, resulting in a remainder of 141.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2574 from 2715 and we're left with 141.
Include the next digit (8) from the dividend after 141, then repeat: 1418 / 858

On to step 5:
When dividing 1418 by 858, we get 1 with a remainder of 560.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 560 after subtracting 858 from 1418.
Bring next digit (2) of the dividend behind the 560 and repeat the process: 5602 / 858

Step 6:
5602 divided by 858 is 6 with a remainder of 454.
Use 6 as the next digit of our solution. 
Result so far: 316.0
The remainder is 454 after subtracting 5148 from 5602.
Append the next digit (2) from the dividend to 454 and continue with: 4542 / 858

Step 7:
858 goes into 4542 5 times with a remainder of 252.
Put 5 as the next digit of the answer. 
Result so far: 3165.0
If we subtract 4290 from 4542, we get 252.
Bring next digit (9) of the dividend behind the 252 and repeat the process: 2529 / 858

On to step 8:
858 can be fit into 2529 2 times, resulting in a remainder of 813.
Use 2 as the next digit of our solution. 
Result so far: 31652.0
The remainder is 813 after subtracting 1716 from 2529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8130, and continue the process.

Step 9:
When dividing 8130 by 858, we get 9 with a remainder of 408.
The number 9 becomes the next digit in our result. 
Result so far: 31652.9
Deduct 7722 from 8130 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 10:
The number 858 fits into 4080 4 times, leaving a remainder of 648.
The number 4 becomes the next digit in our result. 
Result so far: 31652.94
If we subtract 3432 from 4080, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 11:
The number 858 fits into 6480 7 times, leaving a remainder of 474.
Put 7 as the next digit of the answer. 
Result so far: 31652.947
Deduct 6006 from 6480 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 12:
When dividing 4740 by 858, we get 5 with a remainder of 450.
The next digit of our result is 5. 
Result so far: 31652.9475
If we subtract 4290 from 4740, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 13:
858 goes into 4500 5 times with a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 31652.94755
The remainder is 210 after subtracting 4290 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final result is 31652.94755 with a remainder of 0.00021.
