We divide 158581 by 22
We want to figure out the number of times 158581 can be divided by 22.

On to step 1:
If we divide 1 by 22, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 22

Advancing to step 2:
22 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 22

Advancing to step 3:
22 goes into 158 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 154 from 158, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 22

Let's proceed to step 4:
The number 22 fits into 45 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 72.0
If we take 44 away from 45, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 22

On to step 5:
If we divide 18 by 22, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 720.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 22

On to step 6:
The number 22 fits into 181 8 times, leaving a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 7208.0
The remainder is 5 after subtracting 176 from 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 22, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 7208.2
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
60 divided by 22 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 7208.22
Subtract 44 from 60 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 7208.22 and a remainder of 0.016.
