Let's divide 606371 by 21
We want to figure out the number of times 606371 can be divided by 21.

Advancing to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 21

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
If we take 42 away from 60, we end up with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 21

On to step 3:
When dividing 186 by 21, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 168 from 186, we get 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 21

Going ahead to step 4:
21 goes into 183 8 times with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 288.0
If we subtract 168 from 183, we get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 21

Advancing to step 5:
If we divide 157 by 21, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 2887.0
Subtract 147 from 157 to get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 21

Moving on to step 6:
The number 21 fits into 101 4 times, leaving a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 28874.0
Subtracting 84 from 101 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.

Step 7:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 28874.8
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.

Let's proceed to step 8:
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: 28874.8
Subtracting 0 from 20 leaves us 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.

Advancing to step 9:
If we divide 200 by 21, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 28874.809
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.

Step 10:
When dividing 110 by 21, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 28874.8095
Deduct 105 from 110 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.

Step 11:
50 divided by 21 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 28874.80952
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.

Moving on to step 12:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 28874.809523
Subtract 63 from 80 to get 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 13:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 28874.8095238
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.

On to step 14:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 28874.8095238
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.

The quotient of the division is 28874.8095238, and the remainder is 2e-08.
