Let's divide 76280543 by 858
The aim is to understand the frequency of 858 in 76280543.

On to step 1:
When dividing 7 by 858, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 858

Moving on to step 2:
858 can be fit into 76 0 times, resulting in a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Take the next digit (2) from the dividend and append it to 76, then repeat: 762 / 858

On to step 3:
858 can be fit into 762 0 times, resulting in a remainder of 762.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 762 after subtracting 0 from 762.
Take the next digit (8) from the dividend and append it to 762, then repeat: 7628 / 858

Advancing to step 4:
7628 divided by 858 is 8 with a remainder of 764.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 6864 from 7628 leaves us with 764.
Fetch the next digit (0) from the dividend, attach it to 764 and continue: 7640 / 858

Advancing to step 5:
When dividing 7640 by 858, we get 8 with a remainder of 776.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
The remainder is 776 after subtracting 6864 from 7640.
Append the next digit (5) from the dividend to 776 and continue with: 7765 / 858

Going ahead to step 6:
858 goes into 7765 9 times with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 889.0
If we subtract 7722 from 7765, we get 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 858

Going ahead to step 7:
When dividing 434 by 858, we get 0 with a remainder of 434.
Record the quotient 0 as the next digit in the result. 
Result so far: 8890.0
Subtract 0 from 434 to get 434.
Include the next digit (3) from the dividend after 434, then repeat: 4343 / 858

Let's proceed to step 8:
If we divide 4343 by 858, we get 5 and a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 88905.0
If we take 4290 away from 4343, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 9:
530 divided by 858 is 0 with a remainder of 530.
Use 0 as the next digit of our solution. 
Result so far: 88905.0
Subtracting 0 from 530 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 10:
5300 divided by 858 is 6 with a remainder of 152.
The next digit of our result is 6. 
Result so far: 88905.06
If we take 5148 away from 5300, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 11:
858 goes into 1520 1 times with a remainder of 662.
The next digit of our result is 1. 
Result so far: 88905.061
Subtracting 858 from 1520 leaves us with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Advancing to step 12:
If we divide 6620 by 858, we get 7 and a remainder of 614.
Use 7 as the next digit of our solution. 
Result so far: 88905.0617
If we subtract 6006 from 6620, we get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Going ahead to step 13:
6140 divided by 858 is 7 with a remainder of 134.
The next digit of our result is 7. 
Result so far: 88905.06177
If we subtract 6006 from 6140, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

In conclusion, the division gives 88905.06177 with a balance of 0.000134.
