86496359 divided by 658 
The aim is to understand the frequency of 658 in 86496359.

Going ahead to step 1:
The number 658 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 658

Step 2:
The number 658 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 658

Going ahead to step 3:
The number 658 fits into 864 1 times, leaving a remainder of 206.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 658 from 864, we get 206.
Bring next digit (9) of the dividend behind the 206 and repeat the process: 2069 / 658

Step 4:
2069 divided by 658 is 3 with a remainder of 95.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1974 from 2069 leaves us with 95.
Take the next digit (6) from the dividend and append it to 95, then repeat: 956 / 658

Going ahead to step 5:
When dividing 956 by 658, we get 1 with a remainder of 298.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
If we take 658 away from 956, we end up with 298.
Include the next digit (3) from the dividend after 298, then repeat: 2983 / 658

Let's proceed to step 6:
When dividing 2983 by 658, we get 4 with a remainder of 351.
Use 4 as the next digit of our solution. 
Result so far: 1314.0
If we subtract 2632 from 2983, we get 351.
Bring next digit (5) of the dividend behind the 351 and repeat the process: 3515 / 658

On to step 7:
658 can be fit into 3515 5 times, resulting in a remainder of 225.
The next digit of our result is 5. 
Result so far: 13145.0
Subtracting 3290 from 3515 leaves us with 225.
Bring next digit (9) of the dividend behind the 225 and repeat the process: 2259 / 658

Going ahead to step 8:
The number 658 fits into 2259 3 times, leaving a remainder of 285.
The number 3 becomes the next digit in our result. 
Result so far: 131453.0
Subtracting 1974 from 2259 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 9:
The number 658 fits into 2850 4 times, leaving a remainder of 218.
Use 4 as the next digit of our solution. 
Result so far: 131453.4
Deduct 2632 from 2850 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 10:
658 can be fit into 2180 3 times, resulting in a remainder of 206.
Put 3 as the next digit of the answer. 
Result so far: 131453.43
Deduct 1974 from 2180 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 11:
2060 divided by 658 is 3 with a remainder of 86.
The next digit of our result is 3. 
Result so far: 131453.433
Deduct 1974 from 2060 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 131453.433 with a remainder of 0.0086.
