88780213 ÷ 22 
The aim is to understand the frequency of 22 in 88780213.

Step 1:
The number 22 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 22

Step 2:
22 can be fit into 88 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 88 away from 88, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 22

Going ahead to step 3:
22 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 22

Step 4:
78 divided by 22 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 403.0
The remainder is 12 after subtracting 66 from 78.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 22

On to step 5:
When dividing 120 by 22, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 4035.0
Deduct 110 from 120 and we're left with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 22

Let's proceed to step 6:
The number 22 fits into 102 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 40354.0
If we take 88 away from 102, we end up with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 22

Moving on to step 7:
22 can be fit into 141 6 times, resulting in a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 403546.0
If we take 132 away from 141, we end up with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 22

Moving on to step 8:
The number 22 fits into 93 4 times, leaving a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4035464.0
If we take 88 away from 93, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
22 goes into 50 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 4035464.2
The remainder is 6 after subtracting 44 from 50.
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 10:
60 divided by 22 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 4035464.22
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.

After the division, we end up with 4035464.22 and a remainder of 0.016.
