75421981 ÷ 22 
The aim is to understand the frequency of 22 in 75421981.

Going ahead to step 1:
The number 22 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 22

Step 2:
75 divided by 22 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 66 from 75 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 22

Let's proceed to step 3:
When dividing 94 by 22, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 34.0
Subtract 88 from 94 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 22

Advancing to step 4:
If we divide 62 by 22, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 342.0
Subtract 44 from 62 to get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 22

Going ahead to step 5:
The number 22 fits into 181 8 times, leaving a remainder of 5.
The next digit of our result is 8. 
Result so far: 3428.0
If we take 176 away from 181, we end up with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 22

Moving on to step 6:
59 divided by 22 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 34282.0
If we subtract 44 from 59, we get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 22

Advancing to step 7:
If we divide 158 by 22, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 342827.0
Deduct 154 from 158 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 22

Let's proceed to step 8:
When dividing 41 by 22, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 3428271.0
Subtract 22 from 41 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
22 can be fit into 190 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 3428271.8
If we subtract 176 from 190, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
22 goes into 140 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 3428271.86
Subtracting 132 from 140 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
80 divided by 22 is 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3428271.863
Subtract 66 from 80 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
140 divided by 22 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3428271.8636
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
22 goes into 80 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 3428271.86363
The remainder is 14 after subtracting 66 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
22 goes into 140 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 3428271.863636
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 15:
80 divided by 22 is 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3428271.8636363
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 16:
22 goes into 140 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 3428271.86363636
If we take 132 away from 140, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 3428271.86363636, with a leftover of 8e-09.
