84294 divided by 21 
We want to figure out the number of times 84294 can be divided by 21.

Step 1:
When dividing 8 by 21, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 21

Let's proceed to step 2:
21 goes into 84 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 84 away from 84, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 21

On to step 3:
The number 21 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 2 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 21

On to step 4:
When dividing 29 by 21, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 401.0
The remainder is 8 after subtracting 21 from 29.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 21

Step 5:
The number 21 fits into 84 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4014.0
If we take 84 away from 84, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 6:
21 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4014.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 21 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4014.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4014.0, with a leftover of 0.0.
