421607 divided by 22 
The aim is to understand the frequency of 22 in 421607.

Let's proceed to step 1:
If we divide 4 by 22, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 22

Step 2:
22 goes into 42 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 22 from 42 and we're left with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 22

On to step 3:
22 goes into 201 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 198 from 201, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 22

Advancing to step 4:
22 can be fit into 36 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 191.0
Subtract 22 from 36 to get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 22

On to step 5:
22 goes into 140 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 1916.0
The remainder is 8 after subtracting 132 from 140.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 22

On to step 6:
If we divide 87 by 22, we get 3 and a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 19163.0
If we take 66 away from 87, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
When dividing 210 by 22, we get 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 19163.9
Subtract 198 from 210 to get 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 8:
120 divided by 22 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 19163.95
The remainder is 10 after subtracting 110 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 22, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 19163.954
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.

Going ahead to step 10:
If we divide 120 by 22, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 19163.9545
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 11:
The number 22 fits into 100 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 19163.95454
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.

Moving on to step 12:
120 divided by 22 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 19163.954545
The remainder is 10 after subtracting 110 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
If we divide 100 by 22, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 19163.9545454
The remainder is 12 after subtracting 88 from 100.
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 14:
22 goes into 120 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 19163.95454545
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.

Our division results in 19163.95454545 with a remaining 1e-08.
