We look at the division of 359971 by 22 
The aim is to understand the frequency of 22 in 359971.

On to step 1:
22 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 22

On to step 2:
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: 1.0
Subtract 22 from 35 to get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 22

Step 3:
When dividing 139 by 22, we get 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 132 from 139 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 22

Going ahead to step 4:
22 can be fit into 79 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
Subtracting 66 from 79 leaves us with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 22

Step 5:
When dividing 137 by 22, we get 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 1636.0
If we take 132 away from 137, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 22

Let's proceed to step 6:
22 can be fit into 51 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 16362.0
Subtracting 44 from 51 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
22 can be fit into 70 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 16362.3
If we take 66 away from 70, we end up with 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 8:
22 can be fit into 40 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 16362.31
Subtract 22 from 40 to 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.

Step 9:
180 divided by 22 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 16362.318
If we take 176 away from 180, we end up with 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 10:
22 goes into 40 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 16362.3181
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.

Advancing to step 11:
The number 22 fits into 180 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 16362.31818
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.

Advancing to step 12:
22 goes into 40 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 16362.318181
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.

On to step 13:
22 goes into 180 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 16362.3181818
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.

Moving on to step 14:
22 goes into 40 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 16362.31818181
The remainder is 18 after subtracting 22 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 16362.31818181 and a remainder of 1.8e-08.
