25159521 divided by 493 
The aim is to understand the frequency of 493 in 25159521.

Let's proceed to step 1:
The number 493 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 493

Step 2:
When dividing 25 by 493, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 493

Advancing to step 3:
493 can be fit into 251 0 times, resulting in a remainder of 251.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 251 and we're left with 251.
Bring next digit (5) of the dividend behind the 251 and repeat the process: 2515 / 493

Let's proceed to step 4:
493 can be fit into 2515 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 2465 away from 2515, we end up with 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 493

Step 5:
When dividing 509 by 493, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we take 493 away from 509, we end up with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 493

Let's proceed to step 6:
If we divide 165 by 493, we get 0 and a remainder of 165.
The next digit of our result is 0. 
Result so far: 510.0
Deduct 0 from 165 and we're left with 165.
Bring next digit (2) of the dividend behind the 165 and repeat the process: 1652 / 493

Going ahead to step 7:
493 can be fit into 1652 3 times, resulting in a remainder of 173.
Record the quotient 3 as the next digit in the result. 
Result so far: 5103.0
If we take 1479 away from 1652, we end up with 173.
Append the next digit (1) from the dividend to 173 and continue with: 1731 / 493

Let's proceed to step 8:
1731 divided by 493 is 3 with a remainder of 252.
Write down 3 as next digit of the result. 
Result so far: 51033.0
Deduct 1479 from 1731 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 9:
493 goes into 2520 5 times with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 51033.5
The remainder is 55 after subtracting 2465 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
If we divide 550 by 493, we get 1 and a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 51033.51
If we subtract 493 from 550, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 11:
570 divided by 493 is 1 with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 51033.511
Deduct 493 from 570 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

In conclusion, the division gives 51033.511 with a balance of 0.0077.
