We're dividing 90332681 by 858 
The aim is to understand the frequency of 858 in 90332681.

Moving on to step 1:
858 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 858

On to step 2:
858 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 858

Let's proceed to step 3:
If we divide 903 by 858, we get 1 and a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 45 after subtracting 858 from 903.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 858

Advancing to step 4:
453 divided by 858 is 0 with a remainder of 453.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 453, we get 453.
Bring next digit (2) of the dividend behind the 453 and repeat the process: 4532 / 858

Going ahead to step 5:
When dividing 4532 by 858, we get 5 with a remainder of 242.
The next digit of our result is 5. 
Result so far: 105.0
The remainder is 242 after subtracting 4290 from 4532.
Bring next digit (6) of the dividend behind the 242 and repeat the process: 2426 / 858

Advancing to step 6:
858 goes into 2426 2 times with a remainder of 710.
Use 2 as the next digit of our solution. 
Result so far: 1052.0
The remainder is 710 after subtracting 1716 from 2426.
Bring next digit (8) of the dividend behind the 710 and repeat the process: 7108 / 858

Moving on to step 7:
The number 858 fits into 7108 8 times, leaving a remainder of 244.
The number 8 becomes the next digit in our result. 
Result so far: 10528.0
If we take 6864 away from 7108, we end up with 244.
Append the next digit (1) from the dividend to 244 and continue with: 2441 / 858

On to step 8:
When dividing 2441 by 858, we get 2 with a remainder of 725.
Use 2 as the next digit of our solution. 
Result so far: 105282.0
Subtract 1716 from 2441 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Going ahead to step 9:
858 goes into 7250 8 times with a remainder of 386.
Use 8 as the next digit of our solution. 
Result so far: 105282.8
If we subtract 6864 from 7250, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 10:
3860 divided by 858 is 4 with a remainder of 428.
Write down 4 as next digit of the result. 
Result so far: 105282.84
Subtracting 3432 from 3860 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Let's proceed to step 11:
4280 divided by 858 is 4 with a remainder of 848.
Record the quotient 4 as the next digit in the result. 
Result so far: 105282.844
Subtracting 3432 from 4280 leaves us with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

The final result is 105282.844 with a remainder of 0.0848.
