21512993 ÷ 625 
Our goal is to divide 21512993 by 625.

Let's proceed to step 1:
2 divided by 625 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 625

Step 2:
21 divided by 625 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 625

Step 3:
When dividing 215 by 625, we get 0 with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 215, we get 215.
Fetch the next digit (1) from the dividend, attach it to 215 and continue: 2151 / 625

Moving on to step 4:
625 goes into 2151 3 times with a remainder of 276.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1875 from 2151 leaves us with 276.
Append the next digit (2) from the dividend to 276 and continue with: 2762 / 625

Step 5:
2762 divided by 625 is 4 with a remainder of 262.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 2500 from 2762, we get 262.
Fetch the next digit (9) from the dividend, attach it to 262 and continue: 2629 / 625

Step 6:
625 can be fit into 2629 4 times, resulting in a remainder of 129.
Put 4 as the next digit of the answer. 
Result so far: 344.0
Subtracting 2500 from 2629 leaves us with 129.
Bring next digit (9) of the dividend behind the 129 and repeat the process: 1299 / 625

Step 7:
If we divide 1299 by 625, we get 2 and a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 3442.0
The remainder is 49 after subtracting 1250 from 1299.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 625

Moving on to step 8:
The number 625 fits into 493 0 times, leaving a remainder of 493.
Use 0 as the next digit of our solution. 
Result so far: 34420.0
If we subtract 0 from 493, we get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Step 9:
When dividing 4930 by 625, we get 7 with a remainder of 555.
Use 7 as the next digit of our solution. 
Result so far: 34420.7
The remainder is 555 after subtracting 4375 from 4930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Step 10:
625 goes into 5550 8 times with a remainder of 550.
Record the quotient 8 as the next digit in the result. 
Result so far: 34420.78
If we subtract 5000 from 5550, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 11:
The number 625 fits into 5500 8 times, leaving a remainder of 500.
Record the quotient 8 as the next digit in the result. 
Result so far: 34420.788
Subtracting 5000 from 5500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

In conclusion, the division gives 34420.788 with a balance of 0.05.
