We're dividing 86621875 by 486 
The aim is to understand the frequency of 486 in 86621875.

Moving on to step 1:
486 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 486

Going ahead to step 2:
486 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 486

Going ahead to step 3:
486 goes into 866 1 times with a remainder of 380.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 486 from 866, we get 380.
Grab the next digit (2) from the dividend, add it to 380, then carry on: 3802 / 486

Going ahead to step 4:
3802 divided by 486 is 7 with a remainder of 400.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 3402 from 3802 and we're left with 400.
Include the next digit (1) from the dividend after 400, then repeat: 4001 / 486

Going ahead to step 5:
486 goes into 4001 8 times with a remainder of 113.
The next digit of our result is 8. 
Result so far: 178.0
Deduct 3888 from 4001 and we're left with 113.
Fetch the next digit (8) from the dividend, attach it to 113 and continue: 1138 / 486

Let's proceed to step 6:
The number 486 fits into 1138 2 times, leaving a remainder of 166.
The next digit of our result is 2. 
Result so far: 1782.0
Subtract 972 from 1138 to get 166.
Bring next digit (7) of the dividend behind the 166 and repeat the process: 1667 / 486

Let's proceed to step 7:
If we divide 1667 by 486, we get 3 and a remainder of 209.
The number 3 becomes the next digit in our result. 
Result so far: 17823.0
Subtracting 1458 from 1667 leaves us with 209.
Append the next digit (5) from the dividend to 209 and continue with: 2095 / 486

On to step 8:
When dividing 2095 by 486, we get 4 with a remainder of 151.
Record the quotient 4 as the next digit in the result. 
Result so far: 178234.0
The remainder is 151 after subtracting 1944 from 2095.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Moving on to step 9:
When dividing 1510 by 486, we get 3 with a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 178234.3
If we subtract 1458 from 1510, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
The number 486 fits into 520 1 times, leaving a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 178234.31
Deduct 486 from 520 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
340 divided by 486 is 0 with a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 178234.31
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 12:
If we divide 3400 by 486, we get 6 and a remainder of 484.
The number 6 becomes the next digit in our result. 
Result so far: 178234.3106
If we subtract 2916 from 3400, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 13:
If we divide 4840 by 486, we get 9 and a remainder of 466.
Use 9 as the next digit of our solution. 
Result so far: 178234.31069
Subtract 4374 from 4840 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Step 14:
If we divide 4660 by 486, we get 9 and a remainder of 286.
Use 9 as the next digit of our solution. 
Result so far: 178234.310699
Subtracting 4374 from 4660 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

The final result is 178234.310699 with a remainder of 2.86e-05.
