We look at the division of 90727 by 21 
We want to figure out the number of times 90727 can be divided by 21.

Step 1:
21 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 21

Going ahead to step 2:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 84 from 90, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 21

Step 3:
When dividing 67 by 21, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 63 from 67 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 21

Going ahead to step 4:
When dividing 42 by 21, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 432.0
Deduct 42 from 42 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 21

Step 5:
21 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 4320.0
If we take 0 away from 7, we end up 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.

Going ahead to step 6:
If we divide 70 by 21, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 4320.3
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 21, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 4320.33
Subtracting 63 from 70 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.

In conclusion, the division gives 4320.33 with a balance of 0.007.
