86920886 ÷ 487 
The aim is to understand the frequency of 487 in 86920886.

Moving on to step 1:
If we divide 8 by 487, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 487

Step 2:
86 divided by 487 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Grab the next digit (9) from the dividend, add it to 86, then carry on: 869 / 487

Moving on to step 3:
487 goes into 869 1 times with a remainder of 382.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 487 away from 869, we end up with 382.
Take the next digit (2) from the dividend and append it to 382, then repeat: 3822 / 487

Advancing to step 4:
If we divide 3822 by 487, we get 7 and a remainder of 413.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 3409 from 3822 and we're left with 413.
Include the next digit (0) from the dividend after 413, then repeat: 4130 / 487

Let's proceed to step 5:
When dividing 4130 by 487, we get 8 with a remainder of 234.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
Deduct 3896 from 4130 and we're left with 234.
Include the next digit (8) from the dividend after 234, then repeat: 2348 / 487

On to step 6:
If we divide 2348 by 487, we get 4 and a remainder of 400.
The number 4 becomes the next digit in our result. 
Result so far: 1784.0
Subtracting 1948 from 2348 leaves us with 400.
Append the next digit (8) from the dividend to 400 and continue with: 4008 / 487

Let's proceed to step 7:
487 can be fit into 4008 8 times, resulting in a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 17848.0
If we take 3896 away from 4008, we end up with 112.
Append the next digit (6) from the dividend to 112 and continue with: 1126 / 487

Let's proceed to step 8:
When dividing 1126 by 487, we get 2 with a remainder of 152.
Use 2 as the next digit of our solution. 
Result so far: 178482.0
If we take 974 away from 1126, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 9:
When dividing 1520 by 487, we get 3 with a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 178482.3
Deduct 1461 from 1520 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 10:
When dividing 590 by 487, we get 1 with a remainder of 103.
Write down 1 as next digit of the result. 
Result so far: 178482.31
If we subtract 487 from 590, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 11:
1030 divided by 487 is 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 178482.312
If we subtract 974 from 1030, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
487 can be fit into 560 1 times, resulting in a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 178482.3121
Subtracting 487 from 560 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 13:
When dividing 730 by 487, we get 1 with a remainder of 243.
Write down 1 as next digit of the result. 
Result so far: 178482.31211
If we subtract 487 from 730, we get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

The final result is 178482.31211 with a remainder of 0.000243.
