We look at the division of 84246937 by 493 
The aim is to understand the frequency of 493 in 84246937.

On to step 1:
493 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 493

Let's proceed to step 2:
The number 493 fits into 84 0 times, leaving a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Take the next digit (2) from the dividend and append it to 84, then repeat: 842 / 493

Moving on to step 3:
842 divided by 493 is 1 with a remainder of 349.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 349 after subtracting 493 from 842.
Fetch the next digit (4) from the dividend, attach it to 349 and continue: 3494 / 493

Moving on to step 4:
493 can be fit into 3494 7 times, resulting in a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 3451 from 3494 and we're left with 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 493

Step 5:
If we divide 436 by 493, we get 0 and a remainder of 436.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
If we take 0 away from 436, we end up with 436.
Take the next digit (9) from the dividend and append it to 436, then repeat: 4369 / 493

Going ahead to step 6:
493 can be fit into 4369 8 times, resulting in a remainder of 425.
The number 8 becomes the next digit in our result. 
Result so far: 1708.0
The remainder is 425 after subtracting 3944 from 4369.
Fetch the next digit (3) from the dividend, attach it to 425 and continue: 4253 / 493

Step 7:
493 goes into 4253 8 times with a remainder of 309.
Record the quotient 8 as the next digit in the result. 
Result so far: 17088.0
Deduct 3944 from 4253 and we're left with 309.
Append the next digit (7) from the dividend to 309 and continue with: 3097 / 493

Moving on to step 8:
493 can be fit into 3097 6 times, resulting in a remainder of 139.
The next digit of our result is 6. 
Result so far: 170886.0
If we take 2958 away from 3097, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 9:
493 goes into 1390 2 times with a remainder of 404.
The number 2 becomes the next digit in our result. 
Result so far: 170886.2
Deduct 986 from 1390 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 10:
4040 divided by 493 is 8 with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 170886.28
Subtract 3944 from 4040 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 11:
960 divided by 493 is 1 with a remainder of 467.
Record the quotient 1 as the next digit in the result. 
Result so far: 170886.281
The remainder is 467 after subtracting 493 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Advancing to step 12:
If we divide 4670 by 493, we get 9 and a remainder of 233.
The next digit of our result is 9. 
Result so far: 170886.2819
If we subtract 4437 from 4670, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 13:
493 goes into 2330 4 times with a remainder of 358.
Use 4 as the next digit of our solution. 
Result so far: 170886.28194
Deduct 1972 from 2330 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 14:
If we divide 3580 by 493, we get 7 and a remainder of 129.
Put 7 as the next digit of the answer. 
Result so far: 170886.281947
The remainder is 129 after subtracting 3451 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 15:
The number 493 fits into 1290 2 times, leaving a remainder of 304.
The next digit of our result is 2. 
Result so far: 170886.2819472
If we take 986 away from 1290, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 16:
3040 divided by 493 is 6 with a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 170886.28194726
The remainder is 82 after subtracting 2958 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

After the division, we end up with 170886.28194726 and a remainder of 8.2e-08.
