We're dividing 66846950 by 22 
The aim is to understand the frequency of 22 in 66846950.

Going ahead to step 1:
If we divide 6 by 22, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
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

Moving on to step 2:
The number 22 fits into 66 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 66 from 66 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 22

Let's proceed to step 3:
If we divide 8 by 22, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 8 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 22

Going ahead to step 4:
The number 22 fits into 84 3 times, leaving a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 303.0
If we take 66 away from 84, we end up with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 22

On to step 5:
186 divided by 22 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 3038.0
Deduct 176 from 186 and we're left with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 22

Step 6:
If we divide 109 by 22, we get 4 and a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 30384.0
Subtract 88 from 109 to get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 22

Let's proceed to step 7:
The number 22 fits into 215 9 times, leaving a remainder of 17.
The next digit of our result is 9. 
Result so far: 303849.0
If we subtract 198 from 215, we get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 22

On to step 8:
170 divided by 22 is 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 3038497.0
Deduct 154 from 170 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 9:
22 can be fit into 160 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 3038497.7
If we take 154 away from 160, 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.

Moving on to step 10:
If we divide 60 by 22, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 3038497.72
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.

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: 3038497.727
Subtract 154 from 160 to 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 12:
The number 22 fits into 60 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 3038497.7272
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 13:
22 can be fit into 160 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 3038497.72727
If we take 154 away from 160, 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 14:
22 can be fit into 60 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 3038497.727272
The remainder is 16 after subtracting 44 from 60.
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 15:
When dividing 160 by 22, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 3038497.7272727
If we take 154 away from 160, 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.

Step 16:
If we divide 60 by 22, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 3038497.72727272
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.

The final result is 3038497.72727272 with a remainder of 1.6e-08.
