679076 divided by 21 
Let's see how many times 21 fits into 679076.

Advancing to step 1:
21 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 21

Moving on to step 2:
21 goes into 67 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 63 from 67 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 21

Moving on to step 3:
If we divide 49 by 21, we get 2 and a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtracting 42 from 49 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 21

Moving on to step 4:
When dividing 70 by 21, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 323.0
Deduct 63 from 70 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 21

On to step 5:
When dividing 77 by 21, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3233.0
Subtracting 63 from 77 leaves us with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 21

Advancing to step 6:
The number 21 fits into 146 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 32336.0
The remainder is 20 after subtracting 126 from 146.
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 7:
21 goes into 200 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 32336.9
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
If we divide 110 by 21, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 32336.95
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 32336.952
If we subtract 42 from 50, we 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 10:
21 can be fit into 80 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 32336.9523
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.

Advancing to step 11:
When dividing 170 by 21, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 32336.95238
If we take 168 away from 170, we end up 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.

Advancing to step 12:
If we divide 20 by 21, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 32336.95238
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.

Going ahead to step 13:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 32336.9523809
Subtracting 189 from 200 leaves us 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.

Let's proceed to step 14:
If we divide 110 by 21, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 32336.95238095
If we take 105 away from 110, 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.

The final outcome is 32336.95238095, with a leftover of 5e-09.
