We look at the division of 91838457 by 59 
The aim is to understand the frequency of 59 in 91838457.

Going ahead to step 1:
59 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 59

Let's proceed to step 2:
If we divide 91 by 59, we get 1 and a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 59 from 91 to get 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 59

Moving on to step 3:
When dividing 328 by 59, we get 5 with a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 295 away from 328, we end up with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 59

Step 4:
The number 59 fits into 333 5 times, leaving a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 155.0
The remainder is 38 after subtracting 295 from 333.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 59

Going ahead to step 5:
388 divided by 59 is 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 1556.0
If we take 354 away from 388, we end up with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 59

Advancing to step 6:
59 can be fit into 344 5 times, resulting in a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 15565.0
Subtracting 295 from 344 leaves us with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 59

Going ahead to step 7:
59 goes into 495 8 times with a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 155658.0
If we take 472 away from 495, we end up with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 59

Moving on to step 8:
If we divide 237 by 59, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 1556584.0
The remainder is 1 after subtracting 236 from 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
When dividing 10 by 59, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 1556584.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
59 goes into 100 1 times with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 1556584.01
Subtract 59 from 100 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 11:
When dividing 410 by 59, we get 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 1556584.016
If we subtract 354 from 410, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
59 goes into 560 9 times with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 1556584.0169
The remainder is 29 after subtracting 531 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
If we divide 290 by 59, we get 4 and a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 1556584.01694
Subtract 236 from 290 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 14:
59 goes into 540 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 1556584.016949
Subtract 531 from 540 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 15:
When dividing 90 by 59, we get 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 1556584.0169491
If we subtract 59 from 90, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 16:
If we divide 310 by 59, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1556584.01694915
If we subtract 295 from 310, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 1556584.01694915 with a remainder of 1.5e-08.
