We look at the division of 159990 by 22 
We want to divide 159990 by 22.

Going ahead to step 1:
If we divide 1 by 22, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 22

Let's proceed to step 2:
22 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 22

On to step 3:
When dividing 159 by 22, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 154 from 159 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 22

On to step 4:
If we divide 59 by 22, we get 2 and a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 72.0
The remainder is 15 after subtracting 44 from 59.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 22

Let's proceed to step 5:
22 goes into 159 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 727.0
Subtract 154 from 159 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 22

Step 6:
50 divided by 22 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 7272.0
Subtract 44 from 50 to get 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 7:
When dividing 60 by 22, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 7272.2
If we take 44 away from 60, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
When dividing 160 by 22, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7272.27
Subtract 154 from 160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
60 divided by 22 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 7272.272
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.

Moving on to step 10:
When dividing 160 by 22, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 7272.2727
The remainder is 6 after subtracting 154 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
If we divide 60 by 22, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 7272.27272
The remainder is 16 after subtracting 44 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
When dividing 160 by 22, we get 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 7272.272727
Deduct 154 from 160 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.

On to step 13:
22 can be fit into 60 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 7272.2727272
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.

Moving on to step 14:
When dividing 160 by 22, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7272.27272727
Subtract 154 from 160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 7272.27272727 with a balance of 6e-09.
