Let's divide 28087539 by 493
The aim is to understand the frequency of 493 in 28087539.

Advancing to step 1:
If we divide 2 by 493, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 493

On to step 2:
The number 493 fits into 28 0 times, leaving a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 493

Going ahead to step 3:
The number 493 fits into 280 0 times, leaving a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 280, we end up with 280.
Bring next digit (8) of the dividend behind the 280 and repeat the process: 2808 / 493

Let's proceed to step 4:
493 can be fit into 2808 5 times, resulting in a remainder of 343.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 2465 from 2808 and we're left with 343.
Grab the next digit (7) from the dividend, add it to 343, then carry on: 3437 / 493

Moving on to step 5:
If we divide 3437 by 493, we get 6 and a remainder of 479.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtract 2958 from 3437 to get 479.
Include the next digit (5) from the dividend after 479, then repeat: 4795 / 493

Step 6:
493 goes into 4795 9 times with a remainder of 358.
Use 9 as the next digit of our solution. 
Result so far: 569.0
Subtracting 4437 from 4795 leaves us with 358.
Take the next digit (3) from the dividend and append it to 358, then repeat: 3583 / 493

On to step 7:
3583 divided by 493 is 7 with a remainder of 132.
Write down 7 as next digit of the result. 
Result so far: 5697.0
If we subtract 3451 from 3583, we get 132.
Fetch the next digit (9) from the dividend, attach it to 132 and continue: 1329 / 493

Let's proceed to step 8:
1329 divided by 493 is 2 with a remainder of 343.
The number 2 becomes the next digit in our result. 
Result so far: 56972.0
Subtracting 986 from 1329 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 9:
If we divide 3430 by 493, we get 6 and a remainder of 472.
Record the quotient 6 as the next digit in the result. 
Result so far: 56972.6
Deduct 2958 from 3430 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 10:
4720 divided by 493 is 9 with a remainder of 283.
Write down 9 as next digit of the result. 
Result so far: 56972.69
Subtract 4437 from 4720 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 11:
If we divide 2830 by 493, we get 5 and a remainder of 365.
Put 5 as the next digit of the answer. 
Result so far: 56972.695
Subtract 2465 from 2830 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 12:
If we divide 3650 by 493, we get 7 and a remainder of 199.
Use 7 as the next digit of our solution. 
Result so far: 56972.6957
If we take 3451 away from 3650, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Step 13:
When dividing 1990 by 493, we get 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 56972.69574
The remainder is 18 after subtracting 1972 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
180 divided by 493 is 0 with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 56972.69574
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 15:
If we divide 1800 by 493, we get 3 and a remainder of 321.
Use 3 as the next digit of our solution. 
Result so far: 56972.6957403
Subtracting 1479 from 1800 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 16:
493 can be fit into 3210 6 times, resulting in a remainder of 252.
Record the quotient 6 as the next digit in the result. 
Result so far: 56972.69574036
If we subtract 2958 from 3210, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final outcome is 56972.69574036, with a leftover of 2.52e-07.
