We're dividing 915407 by 22 
The aim is to understand the frequency of 22 in 915407.

On to step 1:
9 divided by 22 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 22

Going ahead to step 2:
91 divided by 22 is 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 88 away from 91, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 22

Moving on to step 3:
22 can be fit into 35 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 41.0
The remainder is 13 after subtracting 22 from 35.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 22

Moving on to step 4:
When dividing 134 by 22, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 416.0
If we subtract 132 from 134, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 22

Step 5:
22 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 4160.0
If we subtract 0 from 20, we get 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 22

Going ahead to step 6:
If we divide 207 by 22, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 41609.0
If we subtract 198 from 207, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
22 can be fit into 90 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 41609.4
Deduct 88 from 90 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.

Let's proceed to step 8:
22 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 41609.4
Subtract 0 from 20 to 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.

Going ahead to step 9:
When dividing 200 by 22, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 41609.409
If we subtract 198 from 200, we get 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 10:
20 divided by 22 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 41609.409
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.

Advancing to step 11:
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: 41609.40909
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
22 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 41609.40909
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.

Moving on to step 13:
22 goes into 200 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 41609.4090909
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 14:
If we divide 20 by 22, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 41609.4090909
Subtract 0 from 20 to 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.

The final result is 41609.4090909 with a remainder of 2e-08.
