606947 divided by 21 
We want to divide 606947 by 21.

Advancing to step 1:
6 divided by 21 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 21

Moving on to step 2:
21 goes into 60 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 42 from 60 to get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 21

Advancing to step 3:
21 can be fit into 186 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 168 away from 186, we end up with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 21

Advancing to step 4:
When dividing 189 by 21, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 289.0
Deduct 189 from 189 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 21

Going ahead to step 5:
21 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 2890.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 21

On to step 6:
When dividing 47 by 21, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 28902.0
Deduct 42 from 47 and we're left 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.

Going ahead to step 7:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 28902.2
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.

Step 8:
If we divide 80 by 21, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 28902.23
Deduct 63 from 80 and we're left 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.

Let's proceed to step 9:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 28902.238
The remainder is 2 after subtracting 168 from 170.
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 10:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 28902.238
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 11:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 28902.23809
Deduct 189 from 200 and we're left 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.

Advancing to step 12:
21 goes into 110 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 28902.238095
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.

On to step 13:
If we divide 50 by 21, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 28902.2380952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
21 goes into 80 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 28902.23809523
Deduct 63 from 80 and we're left 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.

The final outcome is 28902.23809523, with a leftover of 1.7e-08.
