We divide 213537 by 22
The aim is to understand the frequency of 22 in 213537.

Moving on to step 1:
The number 22 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 22

Let's proceed to step 2:
21 divided by 22 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 22

On to step 3:
22 goes into 213 9 times with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 198 from 213 and we're left with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 22

On to step 4:
The number 22 fits into 155 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtract 154 from 155 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 22

Let's proceed to step 5:
The number 22 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 970.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 22

Moving on to step 6:
22 can be fit into 137 6 times, resulting in a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 9706.0
If we subtract 132 from 137, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 22, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 9706.2
Subtracting 44 from 50 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 22, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 9706.22
If we subtract 44 from 60, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 9706.22 with a remainder of 0.016.
