901971 divided by 22 
The aim is to understand the frequency of 22 in 901971.

Moving on to step 1:
The number 22 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 22

On to step 2:
If we divide 90 by 22, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 88 away from 90, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 22

On to step 3:
If we divide 21 by 22, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 22

On to step 4:
219 divided by 22 is 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 409.0
Subtracting 198 from 219 leaves us with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 22

On to step 5:
22 goes into 217 9 times with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 4099.0
Subtract 198 from 217 to get 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 22

Let's proceed to step 6:
22 goes into 191 8 times with a remainder of 15.
The next digit of our result is 8. 
Result so far: 40998.0
Subtract 176 from 191 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
22 goes into 150 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 40998.6
Deduct 132 from 150 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
When dividing 180 by 22, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 40998.68
If we subtract 176 from 180, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
The number 22 fits into 40 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 40998.681
If we subtract 22 from 40, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
22 goes into 180 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 40998.6818
The remainder is 4 after subtracting 176 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
When dividing 40 by 22, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 40998.68181
Subtracting 22 from 40 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
22 goes into 180 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 40998.681818
If we subtract 176 from 180, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
When dividing 40 by 22, we get 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 40998.6818181
Subtracting 22 from 40 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
If we divide 180 by 22, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 40998.68181818
Subtract 176 from 180 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 40998.68181818 with a remainder of 4e-09.
