479016 divided by 21 
We want to figure out the number of times 479016 can be divided by 21.

Going ahead to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 21

Step 2:
21 can be fit into 47 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 42 from 47 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 21

Advancing to step 3:
21 goes into 59 2 times with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 17 after subtracting 42 from 59.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 21

Going ahead to step 4:
21 goes into 170 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 228.0
If we take 168 away from 170, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 21

Let's proceed to step 5:
21 can be fit into 21 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 2281.0
Deduct 21 from 21 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 21

Step 6:
The number 21 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 22810.0
If we take 0 away from 6, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 22810.2
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
If we divide 180 by 21, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 22810.28
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
If we divide 120 by 21, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 22810.285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
The number 21 fits into 150 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 22810.2857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
When dividing 30 by 21, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 22810.28571
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
If we divide 90 by 21, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 22810.285714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 22810.2857142
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
21 goes into 180 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 22810.28571428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 22810.28571428 with a remainder of 1.2e-08.
