12354513 ÷ 493 
The aim is to understand the frequency of 493 in 12354513.

Going ahead to step 1:
493 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 493

Advancing to step 2:
The number 493 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 493

On to step 3:
When dividing 123 by 493, we get 0 with a remainder of 123.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 123, we end up with 123.
Bring next digit (5) of the dividend behind the 123 and repeat the process: 1235 / 493

On to step 4:
When dividing 1235 by 493, we get 2 with a remainder of 249.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 986 from 1235 leaves us with 249.
Grab the next digit (4) from the dividend, add it to 249, then carry on: 2494 / 493

Step 5:
2494 divided by 493 is 5 with a remainder of 29.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 2465 from 2494 and we're left with 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 493

Moving on to step 6:
The number 493 fits into 295 0 times, leaving a remainder of 295.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
The remainder is 295 after subtracting 0 from 295.
Fetch the next digit (1) from the dividend, attach it to 295 and continue: 2951 / 493

Moving on to step 7:
If we divide 2951 by 493, we get 5 and a remainder of 486.
Write down 5 as next digit of the result. 
Result so far: 2505.0
The remainder is 486 after subtracting 2465 from 2951.
Grab the next digit (3) from the dividend, add it to 486, then carry on: 4863 / 493

Advancing to step 8:
If we divide 4863 by 493, we get 9 and a remainder of 426.
The number 9 becomes the next digit in our result. 
Result so far: 25059.0
Deduct 4437 from 4863 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Advancing to step 9:
493 can be fit into 4260 8 times, resulting in a remainder of 316.
Record the quotient 8 as the next digit in the result. 
Result so far: 25059.8
Subtract 3944 from 4260 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 10:
If we divide 3160 by 493, we get 6 and a remainder of 202.
Write down 6 as next digit of the result. 
Result so far: 25059.86
Subtract 2958 from 3160 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 11:
The number 493 fits into 2020 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 25059.864
Deduct 1972 from 2020 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
When dividing 480 by 493, we get 0 with a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 25059.864
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 13:
493 can be fit into 4800 9 times, resulting in a remainder of 363.
Write down 9 as next digit of the result. 
Result so far: 25059.86409
Deduct 4437 from 4800 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 14:
If we divide 3630 by 493, we get 7 and a remainder of 179.
Write down 7 as next digit of the result. 
Result so far: 25059.864097
Subtract 3451 from 3630 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 15:
The number 493 fits into 1790 3 times, leaving a remainder of 311.
Put 3 as the next digit of the answer. 
Result so far: 25059.8640973
If we subtract 1479 from 1790, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 16:
3110 divided by 493 is 6 with a remainder of 152.
Write down 6 as next digit of the result. 
Result so far: 25059.86409736
If we subtract 2958 from 3110, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Our division results in 25059.86409736 with a remaining 1.52e-07.
