We look at the division of 86829621 by 494 
The aim is to understand the frequency of 494 in 86829621.

On to step 1:
8 divided by 494 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 494

Moving on to step 2:
The number 494 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (8) from the dividend and append it to 86, then repeat: 868 / 494

On to step 3:
494 can be fit into 868 1 times, resulting in a remainder of 374.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 494 away from 868, we end up with 374.
Include the next digit (2) from the dividend after 374, then repeat: 3742 / 494

Moving on to step 4:
The number 494 fits into 3742 7 times, leaving a remainder of 284.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 284 after subtracting 3458 from 3742.
Fetch the next digit (9) from the dividend, attach it to 284 and continue: 2849 / 494

Moving on to step 5:
494 goes into 2849 5 times with a remainder of 379.
Put 5 as the next digit of the answer. 
Result so far: 175.0
The remainder is 379 after subtracting 2470 from 2849.
Include the next digit (6) from the dividend after 379, then repeat: 3796 / 494

Step 6:
3796 divided by 494 is 7 with a remainder of 338.
Write down 7 as next digit of the result. 
Result so far: 1757.0
If we subtract 3458 from 3796, we get 338.
Take the next digit (2) from the dividend and append it to 338, then repeat: 3382 / 494

On to step 7:
When dividing 3382 by 494, we get 6 with a remainder of 418.
Put 6 as the next digit of the answer. 
Result so far: 17576.0
The remainder is 418 after subtracting 2964 from 3382.
Include the next digit (1) from the dividend after 418, then repeat: 4181 / 494

Moving on to step 8:
When dividing 4181 by 494, we get 8 with a remainder of 229.
Write down 8 as next digit of the result. 
Result so far: 175768.0
The remainder is 229 after subtracting 3952 from 4181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Advancing to step 9:
494 can be fit into 2290 4 times, resulting in a remainder of 314.
Record the quotient 4 as the next digit in the result. 
Result so far: 175768.4
If we take 1976 away from 2290, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 10:
The number 494 fits into 3140 6 times, leaving a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 175768.46
Deduct 2964 from 3140 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 11:
494 goes into 1760 3 times with a remainder of 278.
Record the quotient 3 as the next digit in the result. 
Result so far: 175768.463
The remainder is 278 after subtracting 1482 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Let's proceed to step 12:
The number 494 fits into 2780 5 times, leaving a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 175768.4635
The remainder is 310 after subtracting 2470 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 13:
3100 divided by 494 is 6 with a remainder of 136.
Write down 6 as next digit of the result. 
Result so far: 175768.46356
If we subtract 2964 from 3100, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 14:
1360 divided by 494 is 2 with a remainder of 372.
Use 2 as the next digit of our solution. 
Result so far: 175768.463562
If we take 988 away from 1360, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 15:
3720 divided by 494 is 7 with a remainder of 262.
The next digit of our result is 7. 
Result so far: 175768.4635627
Subtracting 3458 from 3720 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 16:
494 goes into 2620 5 times with a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 175768.46356275
If we subtract 2470 from 2620, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

In conclusion, the division gives 175768.46356275 with a balance of 1.5e-07.
