We look at the division of 667630 by 21 
We want to divide 667630 by 21.

Advancing to step 1:
21 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 21

Going ahead to step 2:
21 goes into 66 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 63 away from 66, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 21

Let's proceed to step 3:
21 can be fit into 37 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 21 from 37 to get 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 21

Let's proceed to step 4:
If we divide 166 by 21, we get 7 and a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 317.0
Subtract 147 from 166 to get 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 21

Advancing to step 5:
21 goes into 193 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 3179.0
If we take 189 away from 193, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 21

Advancing to step 6:
40 divided by 21 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 31791.0
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
If we divide 190 by 21, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 31791.9
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
10 divided by 21 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 31791.9
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
If we divide 100 by 21, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 31791.904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
21 goes into 160 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 31791.9047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
21 goes into 130 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 31791.90476
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
40 divided by 21 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 31791.904761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 13:
21 goes into 190 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 31791.9047619
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
10 divided by 21 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 31791.9047619
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 31791.9047619, and the remainder is 1e-08.
