We look at the division of 19230519 by 858 
The aim is to understand the frequency of 858 in 19230519.

Advancing to step 1:
When dividing 1 by 858, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 858

Let's proceed to step 2:
The number 858 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 858

Moving on to step 3:
858 can be fit into 192 0 times, resulting in a remainder of 192.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 192 to get 192.
Fetch the next digit (3) from the dividend, attach it to 192 and continue: 1923 / 858

Going ahead to step 4:
When dividing 1923 by 858, we get 2 with a remainder of 207.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1716 from 1923, we get 207.
Include the next digit (0) from the dividend after 207, then repeat: 2070 / 858

Advancing to step 5:
If we divide 2070 by 858, we get 2 and a remainder of 354.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we take 1716 away from 2070, we end up with 354.
Take the next digit (5) from the dividend and append it to 354, then repeat: 3545 / 858

Let's proceed to step 6:
3545 divided by 858 is 4 with a remainder of 113.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
The remainder is 113 after subtracting 3432 from 3545.
Include the next digit (1) from the dividend after 113, then repeat: 1131 / 858

Step 7:
The number 858 fits into 1131 1 times, leaving a remainder of 273.
The number 1 becomes the next digit in our result. 
Result so far: 2241.0
If we subtract 858 from 1131, we get 273.
Take the next digit (9) from the dividend and append it to 273, then repeat: 2739 / 858

Advancing to step 8:
2739 divided by 858 is 3 with a remainder of 165.
Use 3 as the next digit of our solution. 
Result so far: 22413.0
Subtract 2574 from 2739 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 9:
858 can be fit into 1650 1 times, resulting in a remainder of 792.
Record the quotient 1 as the next digit in the result. 
Result so far: 22413.1
Subtract 858 from 1650 to get 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Moving on to step 10:
If we divide 7920 by 858, we get 9 and a remainder of 198.
The next digit of our result is 9. 
Result so far: 22413.19
Subtract 7722 from 7920 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 11:
When dividing 1980 by 858, we get 2 with a remainder of 264.
Record the quotient 2 as the next digit in the result. 
Result so far: 22413.192
Subtracting 1716 from 1980 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 12:
If we divide 2640 by 858, we get 3 and a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 22413.1923
Deduct 2574 from 2640 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 13:
858 goes into 660 0 times with a remainder of 660.
Record the quotient 0 as the next digit in the result. 
Result so far: 22413.1923
If we subtract 0 from 660, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 14:
858 can be fit into 6600 7 times, resulting in a remainder of 594.
The number 7 becomes the next digit in our result. 
Result so far: 22413.192307
Subtracting 6006 from 6600 leaves us with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Moving on to step 15:
The number 858 fits into 5940 6 times, leaving a remainder of 792.
Record the quotient 6 as the next digit in the result. 
Result so far: 22413.1923076
Subtracting 5148 from 5940 leaves us with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Advancing to step 16:
If we divide 7920 by 858, we get 9 and a remainder of 198.
Put 9 as the next digit of the answer. 
Result so far: 22413.19230769
Subtract 7722 from 7920 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

In conclusion, the division gives 22413.19230769 with a balance of 1.98e-07.
