383549 divided by 21 
We want to figure out the number of times 383549 can be divided by 21.

Moving on to step 1:
When dividing 3 by 21, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 21

Let's proceed to step 2:
When dividing 38 by 21, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 21 from 38, we get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 21

Going ahead to step 3:
The number 21 fits into 173 8 times, leaving a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 168 from 173 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 21

Let's proceed to step 4:
21 can be fit into 55 2 times, resulting in a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 182.0
Subtracting 42 from 55 leaves us with 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 21

Moving on to step 5:
21 goes into 134 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 1826.0
Subtract 126 from 134 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 21

Let's proceed to step 6:
89 divided by 21 is 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 18264.0
The remainder is 5 after subtracting 84 from 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
21 can be fit into 50 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 18264.2
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
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: 18264.23
The remainder is 17 after subtracting 63 from 80.
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 9:
170 divided by 21 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 18264.238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 18264.238
Subtracting 0 from 20 leaves us with 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 11:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 18264.23809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
21 can be fit into 110 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 18264.238095
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
If we divide 50 by 21, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 18264.2380952
If we take 42 away from 50, we end up 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 14:
80 divided by 21 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 18264.23809523
If we subtract 63 from 80, we 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.

The final outcome is 18264.23809523, with a leftover of 1.7e-08.
