We're dividing 851948 by 22 
The aim is to understand the frequency of 22 in 851948.

Step 1:
When dividing 8 by 22, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 22

Let's proceed to step 2:
22 can be fit into 85 3 times, resulting in a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 66 from 85 leaves us with 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 22

Let's proceed to step 3:
191 divided by 22 is 8 with a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 15 after subtracting 176 from 191.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 22

On to step 4:
22 goes into 159 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 387.0
If we subtract 154 from 159, we get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 22

Advancing to step 5:
22 can be fit into 54 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 3872.0
Deduct 44 from 54 and we're left with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 22

Step 6:
22 can be fit into 108 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 38724.0
If we subtract 88 from 108, 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.

On to step 7:
The number 22 fits into 200 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 38724.9
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.

Step 8:
The number 22 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 38724.9
If we take 0 away from 20, we end up 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 9:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 38724.909
Subtracting 198 from 200 leaves us 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 10:
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: 38724.909
Subtracting 0 from 20 leaves us 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.
The next digit of our result is 9. 
Result so far: 38724.90909
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 12:
If we divide 20 by 22, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 38724.90909
Subtracting 0 from 20 leaves us 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.

Step 13:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 38724.9090909
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.

Moving on to step 14:
The number 22 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 38724.9090909
Subtracting 0 from 20 leaves us 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.

The final result is 38724.9090909 with a remainder of 2e-08.
