905527 ÷ 21 
We're looking to find how many times 21 goes into 905527.

On to step 1:
If we divide 9 by 21, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 21

On to step 2:
90 divided by 21 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 84 from 90 leaves us with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 21

Step 3:
If we divide 65 by 21, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 2 after subtracting 63 from 65.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 21

Advancing to step 4:
When dividing 25 by 21, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 431.0
The remainder is 4 after subtracting 21 from 25.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 21

Let's proceed to step 5:
21 goes into 42 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 4312.0
Subtract 42 from 42 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 21

Advancing to step 6:
When dividing 7 by 21, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 43120.0
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.

On to step 7:
When dividing 70 by 21, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 43120.3
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.

On to step 8:
21 goes into 70 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 43120.33
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 43120.33 with a balance of 0.007.
