14380288 ÷ 486 
The aim is to understand the frequency of 486 in 14380288.

On to step 1:
1 divided by 486 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 486

Let's proceed to step 2:
If we divide 14 by 486, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 486

Going ahead to step 3:
The number 486 fits into 143 0 times, leaving a remainder of 143.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 143 after subtracting 0 from 143.
Bring next digit (8) of the dividend behind the 143 and repeat the process: 1438 / 486

Let's proceed to step 4:
If we divide 1438 by 486, we get 2 and a remainder of 466.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 972 from 1438, we get 466.
Include the next digit (0) from the dividend after 466, then repeat: 4660 / 486

Let's proceed to step 5:
The number 486 fits into 4660 9 times, leaving a remainder of 286.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 4374 away from 4660, we end up with 286.
Include the next digit (2) from the dividend after 286, then repeat: 2862 / 486

On to step 6:
2862 divided by 486 is 5 with a remainder of 432.
Record the quotient 5 as the next digit in the result. 
Result so far: 295.0
Subtracting 2430 from 2862 leaves us with 432.
Append the next digit (8) from the dividend to 432 and continue with: 4328 / 486

Step 7:
4328 divided by 486 is 8 with a remainder of 440.
The next digit of our result is 8. 
Result so far: 2958.0
The remainder is 440 after subtracting 3888 from 4328.
Bring next digit (8) of the dividend behind the 440 and repeat the process: 4408 / 486

Let's proceed to step 8:
The number 486 fits into 4408 9 times, leaving a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 29589.0
Subtract 4374 from 4408 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
If we divide 340 by 486, we get 0 and a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 29589.0
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.

On to step 10:
486 goes into 3400 6 times with a remainder of 484.
Record the quotient 6 as the next digit in the result. 
Result so far: 29589.06
Subtracting 2916 from 3400 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 11:
The number 486 fits into 4840 9 times, leaving a remainder of 466.
Put 9 as the next digit of the answer. 
Result so far: 29589.069
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.

Moving on to step 12:
4660 divided by 486 is 9 with a remainder of 286.
The number 9 becomes the next digit in our result. 
Result so far: 29589.0699
Deduct 4374 from 4660 and we're left 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.

Our division results in 29589.0699 with a remaining 0.00286.
