We look at the division of 50982179 by 858 
The aim is to understand the frequency of 858 in 50982179.

Advancing to step 1:
The number 858 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 858

Going ahead to step 2:
The number 858 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 858

Moving on to step 3:
858 goes into 509 0 times with a remainder of 509.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 509, we end up with 509.
Include the next digit (8) from the dividend after 509, then repeat: 5098 / 858

Moving on to step 4:
5098 divided by 858 is 5 with a remainder of 808.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 4290 from 5098, we get 808.
Take the next digit (2) from the dividend and append it to 808, then repeat: 8082 / 858

Advancing to step 5:
858 can be fit into 8082 9 times, resulting in a remainder of 360.
The next digit of our result is 9. 
Result so far: 59.0
Deduct 7722 from 8082 and we're left with 360.
Fetch the next digit (1) from the dividend, attach it to 360 and continue: 3601 / 858

Advancing to step 6:
The number 858 fits into 3601 4 times, leaving a remainder of 169.
Use 4 as the next digit of our solution. 
Result so far: 594.0
If we subtract 3432 from 3601, we get 169.
Take the next digit (7) from the dividend and append it to 169, then repeat: 1697 / 858

Step 7:
If we divide 1697 by 858, we get 1 and a remainder of 839.
Use 1 as the next digit of our solution. 
Result so far: 5941.0
If we subtract 858 from 1697, we get 839.
Bring next digit (9) of the dividend behind the 839 and repeat the process: 8399 / 858

Going ahead to step 8:
If we divide 8399 by 858, we get 9 and a remainder of 677.
The number 9 becomes the next digit in our result. 
Result so far: 59419.0
Subtract 7722 from 8399 to get 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Moving on to step 9:
6770 divided by 858 is 7 with a remainder of 764.
Write down 7 as next digit of the result. 
Result so far: 59419.7
Subtract 6006 from 6770 to get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Step 10:
7640 divided by 858 is 8 with a remainder of 776.
Write down 8 as next digit of the result. 
Result so far: 59419.78
If we take 6864 away from 7640, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Moving on to step 11:
858 can be fit into 7760 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 59419.789
Subtracting 7722 from 7760 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
380 divided by 858 is 0 with a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 59419.789
If we take 0 away from 380, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 13:
858 goes into 3800 4 times with a remainder of 368.
The next digit of our result is 4. 
Result so far: 59419.78904
If we subtract 3432 from 3800, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 14:
858 can be fit into 3680 4 times, resulting in a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 59419.789044
The remainder is 248 after subtracting 3432 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Our division results in 59419.789044 with a remaining 2.48e-05.
