665120 divided by 22 
The aim is to understand the frequency of 22 in 665120.

Advancing to step 1:
6 divided by 22 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 22

On to step 2:
If we divide 66 by 22, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 66 from 66 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 22

On to step 3:
The number 22 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 22

Advancing to step 4:
22 can be fit into 51 2 times, resulting in a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 302.0
Subtract 44 from 51 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 22

Advancing to step 5:
22 can be fit into 72 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3023.0
Deduct 66 from 72 and we're left with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 22

Step 6:
If we divide 60 by 22, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 30232.0
Deduct 44 from 60 and we're left 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.

Going ahead to step 7:
22 goes into 160 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 30232.7
If we subtract 154 from 160, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
22 can be fit into 60 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 30232.72
Subtract 44 from 60 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
22 goes into 160 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 30232.727
Deduct 154 from 160 and we're left 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.

Step 10:
When dividing 60 by 22, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 30232.7272
If we subtract 44 from 60, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
If we divide 160 by 22, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 30232.72727
Deduct 154 from 160 and we're left 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.

Going ahead to step 12:
22 goes into 60 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 30232.727272
If we take 44 away from 60, 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.

Advancing to step 13:
22 can be fit into 160 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 30232.7272727
If we subtract 154 from 160, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
If we divide 60 by 22, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 30232.72727272
Subtract 44 from 60 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 30232.72727272 with a balance of 1.6e-08.
