86492497 divided by 502 
The aim is to understand the frequency of 502 in 86492497.

On to step 1:
If we divide 8 by 502, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 502

Going ahead to step 2:
502 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 502

Going ahead to step 3:
502 goes into 864 1 times with a remainder of 362.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 362 after subtracting 502 from 864.
Bring next digit (9) of the dividend behind the 362 and repeat the process: 3629 / 502

Step 4:
When dividing 3629 by 502, we get 7 with a remainder of 115.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 3514 from 3629 to get 115.
Bring next digit (2) of the dividend behind the 115 and repeat the process: 1152 / 502

Moving on to step 5:
The number 502 fits into 1152 2 times, leaving a remainder of 148.
The next digit of our result is 2. 
Result so far: 172.0
Subtracting 1004 from 1152 leaves us with 148.
Take the next digit (4) from the dividend and append it to 148, then repeat: 1484 / 502

Moving on to step 6:
502 can be fit into 1484 2 times, resulting in a remainder of 480.
Use 2 as the next digit of our solution. 
Result so far: 1722.0
If we subtract 1004 from 1484, we get 480.
Bring next digit (9) of the dividend behind the 480 and repeat the process: 4809 / 502

On to step 7:
If we divide 4809 by 502, we get 9 and a remainder of 291.
The number 9 becomes the next digit in our result. 
Result so far: 17229.0
If we subtract 4518 from 4809, we get 291.
Fetch the next digit (7) from the dividend, attach it to 291 and continue: 2917 / 502

Going ahead to step 8:
2917 divided by 502 is 5 with a remainder of 407.
Use 5 as the next digit of our solution. 
Result so far: 172295.0
Deduct 2510 from 2917 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Advancing to step 9:
The number 502 fits into 4070 8 times, leaving a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 172295.8
If we take 4016 away from 4070, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
The number 502 fits into 540 1 times, leaving a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 172295.81
The remainder is 38 after subtracting 502 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
380 divided by 502 is 0 with a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 172295.81
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 12:
502 goes into 3800 7 times with a remainder of 286.
Use 7 as the next digit of our solution. 
Result so far: 172295.8107
Subtract 3514 from 3800 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 13:
When dividing 2860 by 502, we get 5 with a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 172295.81075
Subtract 2510 from 2860 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 14:
When dividing 3500 by 502, we get 6 with a remainder of 488.
The number 6 becomes the next digit in our result. 
Result so far: 172295.810756
Subtract 3012 from 3500 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 15:
4880 divided by 502 is 9 with a remainder of 362.
The number 9 becomes the next digit in our result. 
Result so far: 172295.8107569
If we subtract 4518 from 4880, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 16:
502 can be fit into 3620 7 times, resulting in a remainder of 106.
Use 7 as the next digit of our solution. 
Result so far: 172295.81075697
The remainder is 106 after subtracting 3514 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

In conclusion, the division gives 172295.81075697 with a balance of 1.06e-07.
