We're dividing 946221 by 22 
The aim is to understand the frequency of 22 in 946221.

Advancing to step 1:
If we divide 9 by 22, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 22

Step 2:
When dividing 94 by 22, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 88 from 94 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 22

On to step 3:
66 divided by 22 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 66 from 66 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 22

On to step 4:
When dividing 2 by 22, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 430.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 22

Let's proceed to step 5:
When dividing 22 by 22, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 4301.0
Subtract 22 from 22 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 22

Step 6:
When dividing 1 by 22, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 43010.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
22 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 43010.0
If we take 0 away from 10, 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.

On to step 8:
When dividing 100 by 22, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 43010.04
Subtracting 88 from 100 leaves us 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.

On to step 9:
22 can be fit into 120 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 43010.045
If we subtract 110 from 120, we 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 10:
When dividing 100 by 22, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 43010.0454
Deduct 88 from 100 and we're left 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 11:
When dividing 120 by 22, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 43010.04545
If we take 110 away from 120, 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.

Step 12:
22 can be fit into 100 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 43010.045454
If we take 88 away from 100, 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.

Advancing to step 13:
When dividing 120 by 22, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 43010.0454545
Subtracting 110 from 120 leaves us 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.

On to step 14:
The number 22 fits into 100 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 43010.04545454
Subtracting 88 from 100 leaves us 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.

The final result is 43010.04545454 with a remainder of 1.2e-08.
