We look at the division of 384974 by 21 
We're looking to find how many times 21 goes into 384974.

Let's proceed to step 1:
The number 21 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 21

Going ahead to step 2:
21 goes into 38 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
If we take 21 away from 38, we end up with 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 21

Advancing to step 3:
21 can be fit into 174 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 168 away from 174, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 21

Let's proceed to step 4:
21 can be fit into 69 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 183.0
If we subtract 63 from 69, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 21

Going ahead to step 5:
When dividing 67 by 21, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 1833.0
If we take 63 away from 67, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 21

Going ahead to step 6:
If we divide 44 by 21, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 18332.0
The remainder is 2 after subtracting 42 from 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 21 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 18332.0
If we take 0 away from 20, we end up 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.

On to step 8:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 18332.09
If we take 189 away from 200, we end up 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 9:
21 can be fit into 110 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 18332.095
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.

Let's proceed to step 10:
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: 18332.0952
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.

Moving on to step 11:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 18332.09523
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 12:
170 divided by 21 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 18332.095238
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.

Advancing to step 13:
When dividing 20 by 21, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 18332.095238
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.

On to step 14:
When dividing 200 by 21, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 18332.09523809
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.

In conclusion, the division gives 18332.09523809 with a balance of 1.1e-08.
