We're dividing 31325022 by 858 
The aim is to understand the frequency of 858 in 31325022.

Advancing to step 1:
When dividing 3 by 858, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 858

Going ahead to step 2:
The number 858 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 858

Advancing to step 3:
858 can be fit into 313 0 times, resulting in a remainder of 313.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 313, we end up with 313.
Take the next digit (2) from the dividend and append it to 313, then repeat: 3132 / 858

Step 4:
The number 858 fits into 3132 3 times, leaving a remainder of 558.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2574 from 3132, we get 558.
Grab the next digit (5) from the dividend, add it to 558, then carry on: 5585 / 858

Moving on to step 5:
If we divide 5585 by 858, we get 6 and a remainder of 437.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 5148 from 5585, we get 437.
Grab the next digit (0) from the dividend, add it to 437, then carry on: 4370 / 858

Moving on to step 6:
858 can be fit into 4370 5 times, resulting in a remainder of 80.
The next digit of our result is 5. 
Result so far: 365.0
Deduct 4290 from 4370 and we're left with 80.
Grab the next digit (2) from the dividend, add it to 80, then carry on: 802 / 858

Advancing to step 7:
When dividing 802 by 858, we get 0 with a remainder of 802.
Put 0 as the next digit of the answer. 
Result so far: 3650.0
The remainder is 802 after subtracting 0 from 802.
Include the next digit (2) from the dividend after 802, then repeat: 8022 / 858

On to step 8:
858 goes into 8022 9 times with a remainder of 300.
The number 9 becomes the next digit in our result. 
Result so far: 36509.0
If we subtract 7722 from 8022, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 9:
858 can be fit into 3000 3 times, resulting in a remainder of 426.
Use 3 as the next digit of our solution. 
Result so far: 36509.3
Deduct 2574 from 3000 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Step 10:
The number 858 fits into 4260 4 times, leaving a remainder of 828.
The next digit of our result is 4. 
Result so far: 36509.34
If we subtract 3432 from 4260, we get 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Moving on to step 11:
When dividing 8280 by 858, we get 9 with a remainder of 558.
Record the quotient 9 as the next digit in the result. 
Result so far: 36509.349
Deduct 7722 from 8280 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Let's proceed to step 12:
5580 divided by 858 is 6 with a remainder of 432.
The next digit of our result is 6. 
Result so far: 36509.3496
Subtract 5148 from 5580 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 13:
If we divide 4320 by 858, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 36509.34965
The remainder is 30 after subtracting 4290 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
858 goes into 300 0 times with a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 36509.34965
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 15:
If we divide 3000 by 858, we get 3 and a remainder of 426.
The number 3 becomes the next digit in our result. 
Result so far: 36509.3496503
The remainder is 426 after subtracting 2574 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 16:
858 can be fit into 4260 4 times, resulting in a remainder of 828.
Record the quotient 4 as the next digit in the result. 
Result so far: 36509.34965034
If we subtract 3432 from 4260, we get 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

In conclusion, the division gives 36509.34965034 with a balance of 8.28e-07.
