86178306 ÷ 22 
The aim is to understand the frequency of 22 in 86178306.

On to step 1:
When dividing 8 by 22, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 22

Step 2:
22 can be fit into 86 3 times, resulting in a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 66 from 86 to get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 22

On to step 3:
22 goes into 201 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
The remainder is 3 after subtracting 198 from 201.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 22

Going ahead to step 4:
When dividing 37 by 22, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 391.0
Subtract 22 from 37 to get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 22

Going ahead to step 5:
22 goes into 158 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 3917.0
If we subtract 154 from 158, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 22

Let's proceed to step 6:
The number 22 fits into 43 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 39171.0
If we subtract 22 from 43, we get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 22

Let's proceed to step 7:
The number 22 fits into 210 9 times, leaving a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 391719.0
If we subtract 198 from 210, we get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 22

Let's proceed to step 8:
If we divide 126 by 22, we get 5 and a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 3917195.0
If we take 110 away from 126, 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.

Step 9:
22 can be fit into 160 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 3917195.7
Subtract 154 from 160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
If we divide 60 by 22, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 3917195.72
The remainder is 16 after subtracting 44 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
If we divide 160 by 22, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 3917195.727
If we take 154 away from 160, we end up 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.

Moving on to step 12:
22 goes into 60 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 3917195.7272
Subtracting 44 from 60 leaves us 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.

Step 13:
If we divide 160 by 22, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 3917195.72727
Subtract 154 from 160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
The number 22 fits into 60 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 3917195.727272
The remainder is 16 after subtracting 44 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 15:
When dividing 160 by 22, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 3917195.7272727
Subtracting 154 from 160 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.

Advancing to step 16:
22 goes into 60 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 3917195.72727272
The remainder is 16 after subtracting 44 from 60.
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 3917195.72727272 with a remainder of 1.6e-08.
