5989063 ÷ 858 
The aim is to understand the frequency of 858 in 5989063.

On to step 1:
858 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 858

Step 2:
The number 858 fits into 59 0 times, leaving a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Take the next digit (8) from the dividend and append it to 59, then repeat: 598 / 858

Going ahead to step 3:
598 divided by 858 is 0 with a remainder of 598.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 598 after subtracting 0 from 598.
Take the next digit (9) from the dividend and append it to 598, then repeat: 5989 / 858

On to step 4:
858 can be fit into 5989 6 times, resulting in a remainder of 841.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 5148 away from 5989, we end up with 841.
Take the next digit (0) from the dividend and append it to 841, then repeat: 8410 / 858

Step 5:
When dividing 8410 by 858, we get 9 with a remainder of 688.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
If we subtract 7722 from 8410, we get 688.
Include the next digit (6) from the dividend after 688, then repeat: 6886 / 858

Let's proceed to step 6:
When dividing 6886 by 858, we get 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 698.0
If we take 6864 away from 6886, we end up with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 858

Advancing to step 7:
The number 858 fits into 223 0 times, leaving a remainder of 223.
Record the quotient 0 as the next digit in the result. 
Result so far: 6980.0
Subtracting 0 from 223 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 8:
The number 858 fits into 2230 2 times, leaving a remainder of 514.
Write down 2 as next digit of the result. 
Result so far: 6980.2
If we take 1716 away from 2230, we end up with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Step 9:
858 can be fit into 5140 5 times, resulting in a remainder of 850.
Record the quotient 5 as the next digit in the result. 
Result so far: 6980.25
If we subtract 4290 from 5140, we get 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Moving on to step 10:
858 can be fit into 8500 9 times, resulting in a remainder of 778.
Write down 9 as next digit of the result. 
Result so far: 6980.259
The remainder is 778 after subtracting 7722 from 8500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Step 11:
7780 divided by 858 is 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 6980.2599
Subtracting 7722 from 7780 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

In conclusion, the division gives 6980.2599 with a balance of 0.00058.
