30640 ÷ 93 
The aim is to understand the frequency of 93 in 30640.

On to step 1:
If we divide 3 by 93, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 93

Step 2:
The number 93 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 93

Advancing to step 3:
93 can be fit into 306 3 times, resulting in a remainder of 27.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 279 from 306 and we're left with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 93

Step 4:
93 goes into 274 2 times with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we subtract 186 from 274, we get 88.
Append the next digit (0) from the dividend to 88 and continue with: 880 / 93

Moving on to step 5:
The number 93 fits into 880 9 times, leaving a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 329.0
Subtracting 837 from 880 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 6:
430 divided by 93 is 4 with a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 329.4
If we take 372 away from 430, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
580 divided by 93 is 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 329.46
Subtract 558 from 580 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
93 can be fit into 220 2 times, resulting in a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 329.462
Subtract 186 from 220 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
93 goes into 340 3 times with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 329.4623
Subtract 279 from 340 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 10:
610 divided by 93 is 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 329.46236
Subtract 558 from 610 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
93 can be fit into 520 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 329.462365
Deduct 465 from 520 and we're left with 55.
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 12:
93 goes into 550 5 times with a remainder of 85.
The next digit of our result is 5. 
Result so far: 329.4623655
Deduct 465 from 550 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final outcome is 329.4623655, with a leftover of 8.5e-07.
