90895 ÷ 21 
We're looking to find how many times 21 goes into 90895.

On to step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 21

Going ahead to step 2:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 84 away from 90, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 21

Going ahead to step 3:
68 divided by 21 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we subtract 63 from 68, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 21

Let's proceed to step 4:
The number 21 fits into 59 2 times, leaving a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 432.0
If we take 42 away from 59, we end up with 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 21

Moving on to step 5:
When dividing 175 by 21, we get 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 4328.0
If we take 168 away from 175, 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.

Advancing to step 6:
21 can be fit into 70 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 4328.3
Deduct 63 from 70 and we're left 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.

Let's proceed to step 7:
When dividing 70 by 21, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4328.33
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.

The final outcome is 4328.33, with a leftover of 0.007.
