Let's divide 21487713 by 715
Our goal is to divide 21487713 by 715.

Let's proceed to step 1:
715 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 715

Moving on to step 2:
The number 715 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 715

Let's proceed to step 3:
If we divide 214 by 715, we get 0 and a remainder of 214.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 214, we get 214.
Include the next digit (8) from the dividend after 214, then repeat: 2148 / 715

Let's proceed to step 4:
When dividing 2148 by 715, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 2145 from 2148, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 715

Let's proceed to step 5:
If we divide 37 by 715, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 37, we get 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 715

Step 6:
715 can be fit into 377 0 times, resulting in a remainder of 377.
The next digit of our result is 0. 
Result so far: 300.0
If we subtract 0 from 377, we get 377.
Take the next digit (1) from the dividend and append it to 377, then repeat: 3771 / 715

On to step 7:
3771 divided by 715 is 5 with a remainder of 196.
The next digit of our result is 5. 
Result so far: 3005.0
Subtract 3575 from 3771 to get 196.
Bring next digit (3) of the dividend behind the 196 and repeat the process: 1963 / 715

Advancing to step 8:
715 goes into 1963 2 times with a remainder of 533.
The number 2 becomes the next digit in our result. 
Result so far: 30052.0
If we subtract 1430 from 1963, we get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Step 9:
5330 divided by 715 is 7 with a remainder of 325.
Record the quotient 7 as the next digit in the result. 
Result so far: 30052.7
Subtract 5005 from 5330 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 10:
715 can be fit into 3250 4 times, resulting in a remainder of 390.
The number 4 becomes the next digit in our result. 
Result so far: 30052.74
The remainder is 390 after subtracting 2860 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 11:
715 goes into 3900 5 times with a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 30052.745
Subtracting 3575 from 3900 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 12:
3250 divided by 715 is 4 with a remainder of 390.
The next digit of our result is 4. 
Result so far: 30052.7454
The remainder is 390 after subtracting 2860 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 13:
715 can be fit into 3900 5 times, resulting in a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 30052.74545
If we take 3575 away from 3900, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 14:
715 goes into 3250 4 times with a remainder of 390.
The number 4 becomes the next digit in our result. 
Result so far: 30052.745454
Subtract 2860 from 3250 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 15:
If we divide 3900 by 715, we get 5 and a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 30052.7454545
If we take 3575 away from 3900, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 16:
3250 divided by 715 is 4 with a remainder of 390.
The next digit of our result is 4. 
Result so far: 30052.74545454
The remainder is 390 after subtracting 2860 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

In conclusion, the division gives 30052.74545454 with a balance of 3.9e-07.
