We're dividing 171902 by 59 
The aim is to understand the frequency of 59 in 171902.

Advancing to step 1:
59 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 59

Moving on to step 2:
If we divide 17 by 59, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 59

On to step 3:
171 divided by 59 is 2 with a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 118 from 171, we get 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 59

Advancing to step 4:
When dividing 539 by 59, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 29.0
The remainder is 8 after subtracting 531 from 539.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 59

Let's proceed to step 5:
80 divided by 59 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 291.0
The remainder is 21 after subtracting 59 from 80.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 59

Advancing to step 6:
If we divide 212 by 59, we get 3 and a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 2913.0
Subtract 177 from 212 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
When dividing 350 by 59, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 2913.5
The remainder is 55 after subtracting 295 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 8:
If we divide 550 by 59, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 2913.59
Deduct 531 from 550 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
190 divided by 59 is 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 2913.593
Subtract 177 from 190 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
If we divide 130 by 59, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2913.5932
If we subtract 118 from 130, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
The number 59 fits into 120 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2913.59322
Subtracting 118 from 120 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 2913.59322 with a remaining 2e-06.
