77640286 divided by 493 
The aim is to understand the frequency of 493 in 77640286.

Step 1:
7 divided by 493 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 493

Step 2:
493 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 493

Step 3:
The number 493 fits into 776 1 times, leaving a remainder of 283.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 493 from 776 and we're left with 283.
Bring next digit (4) of the dividend behind the 283 and repeat the process: 2834 / 493

Moving on to step 4:
If we divide 2834 by 493, we get 5 and a remainder of 369.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 369 after subtracting 2465 from 2834.
Include the next digit (0) from the dividend after 369, then repeat: 3690 / 493

Going ahead to step 5:
493 can be fit into 3690 7 times, resulting in a remainder of 239.
Use 7 as the next digit of our solution. 
Result so far: 157.0
Subtracting 3451 from 3690 leaves us with 239.
Bring next digit (2) of the dividend behind the 239 and repeat the process: 2392 / 493

Let's proceed to step 6:
If we divide 2392 by 493, we get 4 and a remainder of 420.
Record the quotient 4 as the next digit in the result. 
Result so far: 1574.0
If we take 1972 away from 2392, we end up with 420.
Grab the next digit (8) from the dividend, add it to 420, then carry on: 4208 / 493

Moving on to step 7:
493 can be fit into 4208 8 times, resulting in a remainder of 264.
The number 8 becomes the next digit in our result. 
Result so far: 15748.0
If we take 3944 away from 4208, we end up with 264.
Grab the next digit (6) from the dividend, add it to 264, then carry on: 2646 / 493

Let's proceed to step 8:
The number 493 fits into 2646 5 times, leaving a remainder of 181.
Use 5 as the next digit of our solution. 
Result so far: 157485.0
Deduct 2465 from 2646 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 9:
The number 493 fits into 1810 3 times, leaving a remainder of 331.
Use 3 as the next digit of our solution. 
Result so far: 157485.3
Subtracting 1479 from 1810 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 10:
When dividing 3310 by 493, we get 6 with a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 157485.36
Deduct 2958 from 3310 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 11:
The number 493 fits into 3520 7 times, leaving a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 157485.367
If we subtract 3451 from 3520, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 12:
690 divided by 493 is 1 with a remainder of 197.
Write down 1 as next digit of the result. 
Result so far: 157485.3671
The remainder is 197 after subtracting 493 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 13:
1970 divided by 493 is 3 with a remainder of 491.
Use 3 as the next digit of our solution. 
Result so far: 157485.36713
Subtracting 1479 from 1970 leaves us with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Advancing to step 14:
The number 493 fits into 4910 9 times, leaving a remainder of 473.
Put 9 as the next digit of the answer. 
Result so far: 157485.367139
Deduct 4437 from 4910 and we're left with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Advancing to step 15:
4730 divided by 493 is 9 with a remainder of 293.
The number 9 becomes the next digit in our result. 
Result so far: 157485.3671399
The remainder is 293 after subtracting 4437 from 4730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

The final result is 157485.3671399 with a remainder of 2.93e-06.
