171521 ÷ 93 
The aim is to understand the frequency of 93 in 171521.

Moving on to step 1:
1 divided by 93 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 93

Moving on to step 2:
The number 93 fits into 17 0 times, leaving a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 93

Let's proceed to step 3:
The number 93 fits into 171 1 times, leaving a remainder of 78.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 78 after subtracting 93 from 171.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 93

Step 4:
93 can be fit into 785 8 times, resulting in a remainder of 41.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 744 from 785 and we're left with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 93

Going ahead to step 5:
93 goes into 412 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 184.0
Subtract 372 from 412 to get 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 93

On to step 6:
93 goes into 401 4 times with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 1844.0
If we subtract 372 from 401, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
When dividing 290 by 93, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 1844.3
If we subtract 279 from 290, 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:
When dividing 110 by 93, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1844.31
Subtracting 93 from 110 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
170 divided by 93 is 1 with a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 1844.311
If we take 93 away from 170, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final outcome is 1844.311, with a leftover of 0.0077.
