679711 ÷ 21 
We're looking to find how many times 21 goes into 679711.

Let's proceed to step 1:
The number 21 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 21

Advancing to step 2:
21 goes into 67 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 4 after subtracting 63 from 67.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 21

Advancing to step 3:
49 divided by 21 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtract 42 from 49 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 21

Let's proceed to step 4:
If we divide 77 by 21, we get 3 and a remainder of 14.
The next digit of our result is 3. 
Result so far: 323.0
If we take 63 away from 77, we end up with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 21

Moving on to step 5:
21 can be fit into 141 6 times, resulting in a remainder of 15.
The next digit of our result is 6. 
Result so far: 3236.0
Subtracting 126 from 141 leaves us with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 21

On to step 6:
21 goes into 151 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 32367.0
Subtract 147 from 151 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 21, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 32367.1
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 32367.19
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 32367.19
Deduct 0 from 10 and we're left 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.

Going ahead to step 10:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 32367.1904
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.

On to step 11:
If we divide 160 by 21, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 32367.19047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
130 divided by 21 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 32367.190476
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.

Going ahead to step 13:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 32367.1904761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
190 divided by 21 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 32367.19047619
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.

Our division results in 32367.19047619 with a remaining 1e-09.
