We look at the division of 891910 by 59 
The aim is to understand the frequency of 59 in 891910.

Step 1:
8 divided by 59 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 59

Moving on to step 2:
When dividing 89 by 59, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 59 from 89 to get 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 59

Moving on to step 3:
When dividing 301 by 59, we get 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 295 away from 301, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 59

Going ahead to step 4:
69 divided by 59 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 151.0
If we subtract 59 from 69, we get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 59

Moving on to step 5:
101 divided by 59 is 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 1511.0
Deduct 59 from 101 and we're left with 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 59

Step 6:
If we divide 420 by 59, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 15117.0
Subtracting 413 from 420 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
When dividing 70 by 59, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 15117.1
If we subtract 59 from 70, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
59 can be fit into 110 1 times, resulting in a remainder of 51.
The next digit of our result is 1. 
Result so far: 15117.11
The remainder is 51 after subtracting 59 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Our division results in 15117.11 with a remaining 0.051.
