We divide 390344 by 22
The aim is to understand the frequency of 22 in 390344.

Step 1:
22 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 22

Going ahead to step 2:
The number 22 fits into 39 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 22 from 39, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 22

Step 3:
The number 22 fits into 170 7 times, leaving a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 154 away from 170, we end up with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 22

Step 4:
22 goes into 163 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
If we subtract 154 from 163, we get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 22

Moving on to step 5:
94 divided by 22 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1774.0
Subtract 88 from 94 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 22

Let's proceed to step 6:
When dividing 64 by 22, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 17742.0
If we subtract 44 from 64, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
22 can be fit into 200 9 times, resulting in a remainder of 2.
The next digit of our result is 9. 
Result so far: 17742.9
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 22 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 17742.9
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 22, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 17742.909
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
22 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 17742.909
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
When dividing 200 by 22, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 17742.90909
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
The number 22 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 17742.90909
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
The number 22 fits into 200 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 17742.9090909
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
The number 22 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 17742.9090909
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 17742.9090909 with a remaining 2e-08.
