We divide 62361 by 21
The aim is to understand the frequency of 21 in 62361.

Going ahead to step 1:
6 divided by 21 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 21

Moving on to step 2:
21 goes into 62 2 times with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 42 from 62 and we're left with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 21

Moving on to step 3:
21 can be fit into 203 9 times, resulting in a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we subtract 189 from 203, we get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 21

Moving on to step 4:
146 divided by 21 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 296.0
The remainder is 20 after subtracting 126 from 146.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 21

Moving on to step 5:
If we divide 201 by 21, we get 9 and a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 2969.0
The remainder is 12 after subtracting 189 from 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 6:
120 divided by 21 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 2969.5
Deduct 105 from 120 and we're left 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 7:
If we divide 150 by 21, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 2969.57
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
30 divided by 21 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 2969.571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 2969.5714
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.

Let's proceed to step 10:
21 goes into 60 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 2969.57142
Subtracting 42 from 60 leaves us 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.

On to step 11:
The number 21 fits into 180 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 2969.571428
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
120 divided by 21 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2969.5714285
Deduct 105 from 120 and we're left 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.

Let's proceed to step 13:
21 goes into 150 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 2969.57142857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 2969.57142857, with a leftover of 3e-09.
