2173 ÷ 22 
The aim is to understand the frequency of 22 in 2173.

On to step 1:
If we divide 2 by 22, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 22

On to step 2:
22 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 22

Let's proceed to step 3:
22 goes into 217 9 times with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 198 from 217, we get 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 22

Moving on to step 4:
When dividing 193 by 22, we get 8 with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 98.0
Subtracting 176 from 193 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 5:
When dividing 170 by 22, we get 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 98.7
If we take 154 away from 170, 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.

On to step 6:
When dividing 160 by 22, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 98.77
The remainder is 6 after subtracting 154 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 98.77, and the remainder is 0.006.
