22696201 divided by 21 
The aim is to understand the frequency of 21 in 22696201.

Let's proceed to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 21

Step 2:
The number 21 fits into 22 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 21 from 22 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 21

On to step 3:
16 divided by 21 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 16, we get 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 21

Advancing to step 4:
169 divided by 21 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we subtract 168 from 169, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 21

Going ahead to step 5:
If we divide 16 by 21, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 1080.0
If we subtract 0 from 16, we get 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 21

Moving on to step 6:
21 can be fit into 162 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 10807.0
Subtracting 147 from 162 leaves us with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 21

Moving on to step 7:
21 goes into 150 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 108077.0
Deduct 147 from 150 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 21

Moving on to step 8:
If we divide 31 by 21, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1080771.0
If we take 21 away from 31, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 21, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1080771.4
Subtracting 84 from 100 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.

Advancing to step 10:
21 goes into 160 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 1080771.47
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 1080771.476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1080771.4761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1080771.47619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1080771.47619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 15:
When dividing 100 by 21, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1080771.4761904
If we take 84 away from 100, we end up 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.

Step 16:
When dividing 160 by 21, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 1080771.47619047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 1080771.47619047 and a remainder of 1.3e-08.
