41429200 divided by 858 
The aim is to understand the frequency of 858 in 41429200.

On to step 1:
4 divided by 858 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 858

Let's proceed to step 2:
The number 858 fits into 41 0 times, leaving a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Bring next digit (4) of the dividend behind the 41 and repeat the process: 414 / 858

Let's proceed to step 3:
414 divided by 858 is 0 with a remainder of 414.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 414 after subtracting 0 from 414.
Include the next digit (2) from the dividend after 414, then repeat: 4142 / 858

On to step 4:
The number 858 fits into 4142 4 times, leaving a remainder of 710.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 3432 from 4142 to get 710.
Bring next digit (9) of the dividend behind the 710 and repeat the process: 7109 / 858

Going ahead to step 5:
858 can be fit into 7109 8 times, resulting in a remainder of 245.
Use 8 as the next digit of our solution. 
Result so far: 48.0
The remainder is 245 after subtracting 6864 from 7109.
Include the next digit (2) from the dividend after 245, then repeat: 2452 / 858

On to step 6:
The number 858 fits into 2452 2 times, leaving a remainder of 736.
Use 2 as the next digit of our solution. 
Result so far: 482.0
The remainder is 736 after subtracting 1716 from 2452.
Take the next digit (0) from the dividend and append it to 736, then repeat: 7360 / 858

Let's proceed to step 7:
858 can be fit into 7360 8 times, resulting in a remainder of 496.
Use 8 as the next digit of our solution. 
Result so far: 4828.0
If we subtract 6864 from 7360, we get 496.
Take the next digit (0) from the dividend and append it to 496, then repeat: 4960 / 858

Advancing to step 8:
858 goes into 4960 5 times with a remainder of 670.
Record the quotient 5 as the next digit in the result. 
Result so far: 48285.0
The remainder is 670 after subtracting 4290 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 9:
6700 divided by 858 is 7 with a remainder of 694.
Record the quotient 7 as the next digit in the result. 
Result so far: 48285.7
Subtracting 6006 from 6700 leaves us with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Step 10:
6940 divided by 858 is 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 48285.78
If we subtract 6864 from 6940, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 11:
The number 858 fits into 760 0 times, leaving a remainder of 760.
The next digit of our result is 0. 
Result so far: 48285.78
Deduct 0 from 760 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 12:
When dividing 7600 by 858, we get 8 with a remainder of 736.
The number 8 becomes the next digit in our result. 
Result so far: 48285.7808
Subtract 6864 from 7600 to get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Advancing to step 13:
When dividing 7360 by 858, we get 8 with a remainder of 496.
Record the quotient 8 as the next digit in the result. 
Result so far: 48285.78088
The remainder is 496 after subtracting 6864 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

The final outcome is 48285.78088, with a leftover of 0.000496.
