Let's divide 70430474 by 858
The aim is to understand the frequency of 858 in 70430474.

Let's proceed to step 1:
7 divided by 858 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 858

Step 2:
The number 858 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Bring next digit (4) of the dividend behind the 70 and repeat the process: 704 / 858

Going ahead to step 3:
858 goes into 704 0 times with a remainder of 704.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 704 leaves us with 704.
Append the next digit (3) from the dividend to 704 and continue with: 7043 / 858

Step 4:
7043 divided by 858 is 8 with a remainder of 179.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 6864 from 7043 and we're left with 179.
Append the next digit (0) from the dividend to 179 and continue with: 1790 / 858

Step 5:
858 can be fit into 1790 2 times, resulting in a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Deduct 1716 from 1790 and we're left with 74.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 858

Let's proceed to step 6:
If we divide 744 by 858, we get 0 and a remainder of 744.
Record the quotient 0 as the next digit in the result. 
Result so far: 820.0
Subtracting 0 from 744 leaves us with 744.
Fetch the next digit (7) from the dividend, attach it to 744 and continue: 7447 / 858

Let's proceed to step 7:
The number 858 fits into 7447 8 times, leaving a remainder of 583.
Put 8 as the next digit of the answer. 
Result so far: 8208.0
If we take 6864 away from 7447, we end up with 583.
Bring next digit (4) of the dividend behind the 583 and repeat the process: 5834 / 858

Advancing to step 8:
858 goes into 5834 6 times with a remainder of 686.
Use 6 as the next digit of our solution. 
Result so far: 82086.0
The remainder is 686 after subtracting 5148 from 5834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Advancing to step 9:
858 can be fit into 6860 7 times, resulting in a remainder of 854.
Write down 7 as next digit of the result. 
Result so far: 82086.7
Deduct 6006 from 6860 and we're left with 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

On to step 10:
858 goes into 8540 9 times with a remainder of 818.
The number 9 becomes the next digit in our result. 
Result so far: 82086.79
If we subtract 7722 from 8540, we get 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

Step 11:
8180 divided by 858 is 9 with a remainder of 458.
Write down 9 as next digit of the result. 
Result so far: 82086.799
Subtracting 7722 from 8180 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Our division results in 82086.799 with a remaining 0.0458.
