We're dividing 471216 by 21 
Our goal is to divide 471216 by 21.

On to step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 21

On to step 2:
47 divided by 21 is 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 42 away from 47, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 21

On to step 3:
The number 21 fits into 51 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtracting 42 from 51 leaves us with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 21

Let's proceed to step 4:
21 can be fit into 92 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 224.0
Subtract 84 from 92 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 21

Moving on to step 5:
The number 21 fits into 81 3 times, leaving a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 2243.0
Subtracting 63 from 81 leaves us with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 21

Going ahead to step 6:
186 divided by 21 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 22438.0
The remainder is 18 after subtracting 168 from 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
If we divide 180 by 21, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 22438.8
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
When dividing 120 by 21, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 22438.85
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
When dividing 150 by 21, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 22438.857
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
If we divide 30 by 21, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 22438.8571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
When dividing 90 by 21, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 22438.85714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
21 goes into 60 2 times with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 22438.857142
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
The number 21 fits into 180 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 22438.8571428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 22438.85714285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 22438.85714285 with a remaining 1.5e-08.
