We divide 417317 by 21
Our goal is to divide 417317 by 21.

Advancing to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 21

Step 2:
If we divide 41 by 21, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 21 from 41, we get 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 21

Moving on to step 3:
21 can be fit into 207 9 times, resulting in a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 189 from 207 and we're left with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 21

Moving on to step 4:
21 goes into 183 8 times with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
Deduct 168 from 183 and we're left with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 21

Going ahead to step 5:
21 goes into 151 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 1987.0
The remainder is 4 after subtracting 147 from 151.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 21

On to step 6:
If we divide 47 by 21, we get 2 and a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 19872.0
If we take 42 away from 47, we end up 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.

Advancing 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: 19872.2
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.

On to step 8:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 19872.23
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.

Let's proceed to step 9:
170 divided by 21 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 19872.238
If we subtract 168 from 170, we 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.

Step 10:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 19872.238
Deduct 0 from 20 and we're left 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.

Step 11:
200 divided by 21 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 19872.23809
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.

Going ahead to step 12:
When dividing 110 by 21, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 19872.238095
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.

Let's proceed to step 13:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 19872.2380952
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.

Advancing to step 14:
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: 19872.23809523
Subtracting 63 from 80 leaves us 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.

The quotient of the division is 19872.23809523, and the remainder is 1.7e-08.
