We're dividing 383345 by 21 
Let's see how many times 21 fits into 383345.

Advancing to step 1:
3 divided by 21 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 21

Let's proceed to step 2:
38 divided by 21 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 21 from 38 and we're left with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 21

Going ahead to step 3:
The number 21 fits into 173 8 times, leaving a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 168 away from 173, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 21

Step 4:
When dividing 53 by 21, we get 2 with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 182.0
Subtracting 42 from 53 leaves us with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 21

Going ahead to step 5:
114 divided by 21 is 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 1825.0
Subtracting 105 from 114 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 21

Let's proceed to step 6:
If we divide 95 by 21, we get 4 and a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 18254.0
Subtracting 84 from 95 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.

On to step 7:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 18254.5
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 18254.52
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.

Advancing to step 9:
80 divided by 21 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 18254.523
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.

Let's proceed to step 10:
When dividing 170 by 21, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 18254.5238
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.

Step 11:
21 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 18254.5238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 18254.523809
The remainder is 11 after subtracting 189 from 200.
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 13:
110 divided by 21 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 18254.5238095
Subtract 105 from 110 to 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.

Moving on to step 14:
50 divided by 21 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 18254.52380952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 18254.52380952 and a remainder of 8e-09.
