We look at the division of 87647843 by 498 
The aim is to understand the frequency of 498 in 87647843.

On to step 1:
The number 498 fits into 8 0 times, leaving 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 (7) from the dividend after 8, then repeat: 87 / 498

Let's proceed to step 2:
498 can be fit into 87 0 times, resulting in a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Append the next digit (6) from the dividend to 87 and continue with: 876 / 498

Step 3:
876 divided by 498 is 1 with a remainder of 378.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 498 away from 876, we end up with 378.
Append the next digit (4) from the dividend to 378 and continue with: 3784 / 498

Moving on to step 4:
The number 498 fits into 3784 7 times, leaving a remainder of 298.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 3486 from 3784, we get 298.
Append the next digit (7) from the dividend to 298 and continue with: 2987 / 498

Advancing to step 5:
2987 divided by 498 is 5 with a remainder of 497.
The number 5 becomes the next digit in our result. 
Result so far: 175.0
The remainder is 497 after subtracting 2490 from 2987.
Bring next digit (8) of the dividend behind the 497 and repeat the process: 4978 / 498

On to step 6:
498 goes into 4978 9 times with a remainder of 496.
The next digit of our result is 9. 
Result so far: 1759.0
The remainder is 496 after subtracting 4482 from 4978.
Include the next digit (4) from the dividend after 496, then repeat: 4964 / 498

Step 7:
If we divide 4964 by 498, we get 9 and a remainder of 482.
The number 9 becomes the next digit in our result. 
Result so far: 17599.0
If we take 4482 away from 4964, we end up with 482.
Take the next digit (3) from the dividend and append it to 482, then repeat: 4823 / 498

On to step 8:
The number 498 fits into 4823 9 times, leaving a remainder of 341.
Use 9 as the next digit of our solution. 
Result so far: 175999.0
Deduct 4482 from 4823 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Step 9:
3410 divided by 498 is 6 with a remainder of 422.
Use 6 as the next digit of our solution. 
Result so far: 175999.6
Subtract 2988 from 3410 to get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Let's proceed to step 10:
If we divide 4220 by 498, we get 8 and a remainder of 236.
Write down 8 as next digit of the result. 
Result so far: 175999.68
Subtracting 3984 from 4220 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 11:
498 can be fit into 2360 4 times, resulting in a remainder of 368.
Record the quotient 4 as the next digit in the result. 
Result so far: 175999.684
If we take 1992 away from 2360, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 12:
The number 498 fits into 3680 7 times, leaving a remainder of 194.
The number 7 becomes the next digit in our result. 
Result so far: 175999.6847
Subtracting 3486 from 3680 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 13:
If we divide 1940 by 498, we get 3 and a remainder of 446.
Put 3 as the next digit of the answer. 
Result so far: 175999.68473
If we subtract 1494 from 1940, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 14:
If we divide 4460 by 498, we get 8 and a remainder of 476.
Use 8 as the next digit of our solution. 
Result so far: 175999.684738
Subtract 3984 from 4460 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 15:
If we divide 4760 by 498, we get 9 and a remainder of 278.
Use 9 as the next digit of our solution. 
Result so far: 175999.6847389
If we take 4482 away from 4760, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 16:
2780 divided by 498 is 5 with a remainder of 290.
Record the quotient 5 as the next digit in the result. 
Result so far: 175999.68473895
The remainder is 290 after subtracting 2490 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

In conclusion, the division gives 175999.68473895 with a balance of 2.9e-07.
