934549 divided by 21 
Let's see how many times 21 fits into 934549.

Moving on to step 1:
If we divide 9 by 21, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 21

Step 2:
If we divide 93 by 21, we get 4 and a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 84 from 93 leaves us with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 21

Going ahead to step 3:
If we divide 94 by 21, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 44.0
The remainder is 10 after subtracting 84 from 94.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 21

Let's proceed to step 4:
21 goes into 105 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 445.0
The remainder is 0 after subtracting 105 from 105.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 21

Going ahead to step 5:
The number 21 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 4450.0
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 21

Going ahead to step 6:
49 divided by 21 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 44502.0
Deduct 42 from 49 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.

Advancing to step 7:
21 goes into 70 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 44502.3
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.

Advancing 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: 44502.33
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 44502.33, with a leftover of 0.007.
