991503 ÷ 59 
The aim is to understand the frequency of 59 in 991503.

Let's proceed to step 1:
The number 59 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 59

Step 2:
59 goes into 99 1 times with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 59 from 99 to get 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 59

Step 3:
The number 59 fits into 401 6 times, leaving a remainder of 47.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 354 from 401 to get 47.
Take the next digit (5) from the dividend and append it to 47, then repeat: 475 / 59

Moving on to step 4:
59 can be fit into 475 8 times, resulting in a remainder of 3.
The next digit of our result is 8. 
Result so far: 168.0
The remainder is 3 after subtracting 472 from 475.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 59

Let's proceed to step 5:
30 divided by 59 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1680.0
Subtract 0 from 30 to get 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 59

Let's proceed to step 6:
59 goes into 303 5 times with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 16805.0
The remainder is 8 after subtracting 295 from 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
80 divided by 59 is 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 16805.1
Subtracting 59 from 80 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
59 can be fit into 210 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 16805.13
The remainder is 33 after subtracting 177 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
330 divided by 59 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 16805.135
Subtracting 295 from 330 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
59 goes into 350 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 16805.1355
Subtract 295 from 350 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 16805.1355 with a remainder of 0.00055.
