Let's divide 288517 by 21
Let's see how many times 21 fits into 288517.

Let's proceed to step 1:
2 divided by 21 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 21

Going ahead to step 2:
21 goes into 28 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 21 away from 28, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 21

On to step 3:
21 goes into 78 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 63 from 78 and we're left with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 21

Let's proceed to step 4:
When dividing 155 by 21, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 137.0
The remainder is 8 after subtracting 147 from 155.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 21

On to step 5:
If we divide 81 by 21, we get 3 and a remainder of 18.
The next digit of our result is 3. 
Result so far: 1373.0
If we subtract 63 from 81, we get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 21

Advancing to step 6:
When dividing 187 by 21, we get 8 with a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 13738.0
Deduct 168 from 187 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
When dividing 190 by 21, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 13738.9
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
10 divided by 21 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 13738.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 21 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 13738.904
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
When dividing 160 by 21, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 13738.9047
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 13738.90476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 13738.904761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 13738.9047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13738.9047619
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 13738.9047619 with a balance of 1e-08.
