321425 ÷ 93 
The aim is to understand the frequency of 93 in 321425.

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
Subtracting 0 from 3 leaves us with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 93

Going ahead to step 2:
If we divide 32 by 93, we get 0 and a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 93

Advancing to step 3:
When dividing 321 by 93, we get 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 279 from 321 leaves us with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 93

On to step 4:
424 divided by 93 is 4 with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Deduct 372 from 424 and we're left with 52.
Append the next digit (2) from the dividend to 52 and continue with: 522 / 93

Advancing to step 5:
93 goes into 522 5 times with a remainder of 57.
Put 5 as the next digit of the answer. 
Result so far: 345.0
Subtract 465 from 522 to get 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 93

Going ahead to step 6:
If we divide 575 by 93, we get 6 and a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 3456.0
The remainder is 17 after subtracting 558 from 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 93 fits into 170 1 times, leaving a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 3456.1
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.

Going ahead to step 8:
If we divide 770 by 93, we get 8 and a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 3456.18
Subtract 744 from 770 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
If we divide 260 by 93, we get 2 and a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 3456.182
If we subtract 186 from 260, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
When dividing 740 by 93, we get 7 with a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 3456.1827
Deduct 651 from 740 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 11:
93 goes into 890 9 times with a remainder of 53.
The next digit of our result is 9. 
Result so far: 3456.18279
The remainder is 53 after subtracting 837 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 12:
93 goes into 530 5 times with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 3456.182795
If we take 465 away from 530, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 13:
The number 93 fits into 650 6 times, leaving a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 3456.1827956
If we subtract 558 from 650, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 14:
If we divide 920 by 93, we get 9 and a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 3456.18279569
If we take 837 away from 920, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final result is 3456.18279569 with a remainder of 8.3e-08.
