We're dividing 293890 by 21 
Our goal is to divide 293890 by 21.

Advancing to step 1:
21 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 21

Let's proceed to step 2:
21 goes into 29 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 21 from 29, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 21

Advancing to step 3:
21 can be fit into 83 3 times, resulting in a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 63 from 83 leaves us with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 21

On to step 4:
208 divided by 21 is 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 139.0
Subtracting 189 from 208 leaves us with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 21

On to step 5:
The number 21 fits into 199 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 1399.0
If we take 189 away from 199, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 21

On to step 6:
21 goes into 100 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 13994.0
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 13994.7
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
The number 21 fits into 130 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 13994.76
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
If we divide 40 by 21, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 13994.761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
21 goes into 190 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 13994.7619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 13994.7619
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
100 divided by 21 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 13994.761904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 13994.7619047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
If we divide 130 by 21, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 13994.76190476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 13994.76190476 with a balance of 4e-09.
