607223 divided by 21 
Let's see how many times 21 fits into 607223.

Let's proceed to step 1:
The number 21 fits into 6 0 times, leaving 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.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 21

On to step 2:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 42 from 60 to get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 21

Going ahead to step 3:
21 goes into 187 8 times with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 168 from 187 to get 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 21

Advancing to step 4:
192 divided by 21 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 289.0
If we subtract 189 from 192, we get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 21

Moving on to step 5:
21 goes into 32 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 2891.0
If we subtract 21 from 32, we get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 21

Step 6:
If we divide 113 by 21, we get 5 and a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 28915.0
Subtract 105 from 113 to 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.

Going ahead to step 7:
The number 21 fits into 80 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 28915.3
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.

On to step 8:
If we divide 170 by 21, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 28915.38
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.

Let's proceed to step 9:
20 divided by 21 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 28915.38
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.

Moving on to step 10:
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: 28915.3809
If we subtract 189 from 200, we 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.

Advancing to step 11:
When dividing 110 by 21, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 28915.38095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
21 goes into 50 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 28915.380952
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.

Let's proceed to step 13:
80 divided by 21 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 28915.3809523
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.

Moving on to step 14:
21 goes into 170 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 28915.38095238
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.

In conclusion, the division gives 28915.38095238 with a balance of 2e-09.
