We're dividing 21602587 by 93 
The aim is to understand the frequency of 93 in 21602587.

Advancing to step 1:
The number 93 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 93

Let's proceed to step 2:
If we divide 21 by 93, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 93

Moving on to step 3:
When dividing 216 by 93, we get 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 186 from 216 and we're left with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 93

Let's proceed to step 4:
93 goes into 300 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 279 from 300 and we're left with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 93

Step 5:
When dividing 212 by 93, we get 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 232.0
Deduct 186 from 212 and we're left with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 93

On to step 6:
If we divide 265 by 93, we get 2 and a remainder of 79.
Write down 2 as next digit of the result. 
Result so far: 2322.0
If we subtract 186 from 265, we get 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 93

Advancing to step 7:
798 divided by 93 is 8 with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 23228.0
If we take 744 away from 798, we end up with 54.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 93

Advancing to step 8:
547 divided by 93 is 5 with a remainder of 82.
Use 5 as the next digit of our solution. 
Result so far: 232285.0
If we take 465 away from 547, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
93 can be fit into 820 8 times, resulting in a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 232285.8
Subtracting 744 from 820 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
93 goes into 760 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 232285.88
Subtracting 744 from 760 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 232285.88 with a remaining 0.016.
