We're dividing 27853105 by 858 
The aim is to understand the frequency of 858 in 27853105.

On to step 1:
If we divide 2 by 858, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 858

Moving on to step 2:
27 divided by 858 is 0 with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 858

Step 3:
858 goes into 278 0 times with a remainder of 278.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 278 and we're left with 278.
Fetch the next digit (5) from the dividend, attach it to 278 and continue: 2785 / 858

Let's proceed to step 4:
When dividing 2785 by 858, we get 3 with a remainder of 211.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 2574 away from 2785, we end up with 211.
Bring next digit (3) of the dividend behind the 211 and repeat the process: 2113 / 858

Going ahead to step 5:
The number 858 fits into 2113 2 times, leaving a remainder of 397.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtract 1716 from 2113 to get 397.
Take the next digit (1) from the dividend and append it to 397, then repeat: 3971 / 858

Advancing to step 6:
858 goes into 3971 4 times with a remainder of 539.
Write down 4 as next digit of the result. 
Result so far: 324.0
The remainder is 539 after subtracting 3432 from 3971.
Bring next digit (0) of the dividend behind the 539 and repeat the process: 5390 / 858

Step 7:
858 can be fit into 5390 6 times, resulting in a remainder of 242.
The number 6 becomes the next digit in our result. 
Result so far: 3246.0
If we subtract 5148 from 5390, we get 242.
Bring next digit (5) of the dividend behind the 242 and repeat the process: 2425 / 858

On to step 8:
When dividing 2425 by 858, we get 2 with a remainder of 709.
The number 2 becomes the next digit in our result. 
Result so far: 32462.0
Subtract 1716 from 2425 to get 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Going ahead to step 9:
7090 divided by 858 is 8 with a remainder of 226.
Use 8 as the next digit of our solution. 
Result so far: 32462.8
If we take 6864 away from 7090, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 10:
858 goes into 2260 2 times with a remainder of 544.
Write down 2 as next digit of the result. 
Result so far: 32462.82
If we subtract 1716 from 2260, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 11:
When dividing 5440 by 858, we get 6 with a remainder of 292.
The number 6 becomes the next digit in our result. 
Result so far: 32462.826
The remainder is 292 after subtracting 5148 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 12:
858 can be fit into 2920 3 times, resulting in a remainder of 346.
Put 3 as the next digit of the answer. 
Result so far: 32462.8263
If we take 2574 away from 2920, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 13:
3460 divided by 858 is 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 32462.82634
The remainder is 28 after subtracting 3432 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
858 goes into 280 0 times with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 32462.82634
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
The number 858 fits into 2800 3 times, leaving a remainder of 226.
Use 3 as the next digit of our solution. 
Result so far: 32462.8263403
Deduct 2574 from 2800 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 16:
858 can be fit into 2260 2 times, resulting in a remainder of 544.
The number 2 becomes the next digit in our result. 
Result so far: 32462.82634032
If we subtract 1716 from 2260, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

The final result is 32462.82634032 with a remainder of 5.44e-07.
