679946 ÷ 21 
We want to divide 679946 by 21.

Going ahead to step 1:
6 divided by 21 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 21

Let's proceed to step 2:
21 goes into 67 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 63 from 67, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 21

Advancing to step 3:
49 divided by 21 is 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 32.0
If we take 42 away from 49, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 21

Step 4:
The number 21 fits into 79 3 times, leaving a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 323.0
Subtract 63 from 79 to get 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 21

Advancing to step 5:
21 can be fit into 164 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 3237.0
Subtracting 147 from 164 leaves us with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 21

Let's proceed to step 6:
21 goes into 176 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 32378.0
Subtracting 168 from 176 leaves us with 8.
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 7:
80 divided by 21 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 32378.3
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 8:
21 goes into 170 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 32378.38
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
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: 32378.38
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
200 divided by 21 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 32378.3809
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.

Moving on to step 11:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 32378.38095
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.

Advancing to step 12:
If we divide 50 by 21, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 32378.380952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 32378.3809523
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.

Advancing to step 14:
When dividing 170 by 21, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 32378.38095238
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.

The quotient of the division is 32378.38095238, and the remainder is 2e-09.
