158999 divided by 22 
Let's see how many times 22 fits into 158999.

Step 1:
22 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 22

Advancing to step 2:
The number 22 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 22

Step 3:
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: 7.0
If we subtract 154 from 158, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 22

Moving on to step 4:
When dividing 49 by 22, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 5 after subtracting 44 from 49.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 22

Going ahead to step 5:
The number 22 fits into 59 2 times, leaving a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 722.0
If we take 44 away from 59, we end up with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 22

Step 6:
22 goes into 159 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 7227.0
Subtracting 154 from 159 leaves us with 5.
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:
The number 22 fits into 50 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 7227.2
Deduct 44 from 50 and we're left with 6.
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.
Use 2 as the next digit of our solution. 
Result so far: 7227.22
If we subtract 44 from 60, we 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 7227.22 and a remainder of 0.016.
