86971291 divided by 496 
The aim is to understand the frequency of 496 in 86971291.

Going ahead to step 1:
496 goes into 8 0 times with 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.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 496

Let's proceed to step 2:
496 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (9) from the dividend to 86 and continue with: 869 / 496

Step 3:
496 goes into 869 1 times with a remainder of 373.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 373 after subtracting 496 from 869.
Append the next digit (7) from the dividend to 373 and continue with: 3737 / 496

Going ahead to step 4:
496 goes into 3737 7 times with a remainder of 265.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 3472 from 3737 and we're left with 265.
Take the next digit (1) from the dividend and append it to 265, then repeat: 2651 / 496

Let's proceed to step 5:
If we divide 2651 by 496, we get 5 and a remainder of 171.
The next digit of our result is 5. 
Result so far: 175.0
If we take 2480 away from 2651, we end up with 171.
Include the next digit (2) from the dividend after 171, then repeat: 1712 / 496

On to step 6:
When dividing 1712 by 496, we get 3 with a remainder of 224.
Use 3 as the next digit of our solution. 
Result so far: 1753.0
The remainder is 224 after subtracting 1488 from 1712.
Fetch the next digit (9) from the dividend, attach it to 224 and continue: 2249 / 496

Let's proceed to step 7:
2249 divided by 496 is 4 with a remainder of 265.
Write down 4 as next digit of the result. 
Result so far: 17534.0
If we subtract 1984 from 2249, we get 265.
Fetch the next digit (1) from the dividend, attach it to 265 and continue: 2651 / 496

Advancing to step 8:
The number 496 fits into 2651 5 times, leaving a remainder of 171.
The next digit of our result is 5. 
Result so far: 175345.0
Deduct 2480 from 2651 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 9:
1710 divided by 496 is 3 with a remainder of 222.
The number 3 becomes the next digit in our result. 
Result so far: 175345.3
Deduct 1488 from 1710 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 10:
496 goes into 2220 4 times with a remainder of 236.
The number 4 becomes the next digit in our result. 
Result so far: 175345.34
Subtract 1984 from 2220 to get 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:
When dividing 2360 by 496, we get 4 with a remainder of 376.
The next digit of our result is 4. 
Result so far: 175345.344
If we subtract 1984 from 2360, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final outcome is 175345.344, with a leftover of 0.0376.
