Let's divide 93342 by 21
The aim is to understand the frequency of 21 in 93342.

Let's proceed to step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 21

Moving on to step 2:
When dividing 93 by 21, we get 4 with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 84 from 93 and we're left with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 21

Advancing to step 3:
21 goes into 93 4 times with a remainder of 9.
The next digit of our result is 4. 
Result so far: 44.0
If we subtract 84 from 93, we get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 21

Step 4:
When dividing 94 by 21, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 444.0
Subtract 84 from 94 to get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 21

Step 5:
If we divide 102 by 21, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 4444.0
The remainder is 18 after subtracting 84 from 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 6:
180 divided by 21 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 4444.8
Subtract 168 from 180 to 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.

Going ahead to step 7:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 4444.85
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
When dividing 150 by 21, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 4444.857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
If we divide 30 by 21, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 4444.8571
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
If we divide 90 by 21, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4444.85714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
If we divide 60 by 21, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 4444.857142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
When dividing 180 by 21, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 4444.8571428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
When dividing 120 by 21, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4444.85714285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 4444.85714285 with a balance of 1.5e-08.
