169793 divided by 21 
We want to figure out the number of times 169793 can be divided by 21.

Let's proceed to step 1:
When dividing 1 by 21, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 21

Let's proceed to step 2:
21 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 21

Step 3:
If we divide 169 by 21, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 1 after subtracting 168 from 169.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 21

Let's proceed to step 4:
21 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 80.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 21

Advancing to step 5:
21 goes into 179 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 808.0
If we take 168 away from 179, we end up with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 21

Step 6:
The number 21 fits into 113 5 times, leaving a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 8085.0
Subtracting 105 from 113 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
If we divide 80 by 21, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 8085.3
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
21 goes into 170 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8085.38
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
If we divide 20 by 21, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 8085.38
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
When dividing 200 by 21, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 8085.3809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
110 divided by 21 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 8085.38095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
50 divided by 21 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 8085.380952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
If we divide 80 by 21, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 8085.3809523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
170 divided by 21 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8085.38095238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 8085.38095238 and a remainder of 2e-09.
