We're dividing 53184765 by 486 
The aim is to understand the frequency of 486 in 53184765.

Step 1:
If we divide 5 by 486, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 486

On to step 2:
If we divide 53 by 486, we get 0 and a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 486

Advancing to step 3:
486 can be fit into 531 1 times, resulting in a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 486 from 531, we get 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 486

Advancing to step 4:
486 can be fit into 458 0 times, resulting in a remainder of 458.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 458 leaves us with 458.
Fetch the next digit (4) from the dividend, attach it to 458 and continue: 4584 / 486

Going ahead to step 5:
486 can be fit into 4584 9 times, resulting in a remainder of 210.
Write down 9 as next digit of the result. 
Result so far: 109.0
Subtracting 4374 from 4584 leaves us with 210.
Append the next digit (7) from the dividend to 210 and continue with: 2107 / 486

Going ahead to step 6:
If we divide 2107 by 486, we get 4 and a remainder of 163.
The number 4 becomes the next digit in our result. 
Result so far: 1094.0
The remainder is 163 after subtracting 1944 from 2107.
Include the next digit (6) from the dividend after 163, then repeat: 1636 / 486

Step 7:
When dividing 1636 by 486, we get 3 with a remainder of 178.
Use 3 as the next digit of our solution. 
Result so far: 10943.0
If we subtract 1458 from 1636, we get 178.
Bring next digit (5) of the dividend behind the 178 and repeat the process: 1785 / 486

Let's proceed to step 8:
486 goes into 1785 3 times with a remainder of 327.
The number 3 becomes the next digit in our result. 
Result so far: 109433.0
Subtract 1458 from 1785 to get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 9:
3270 divided by 486 is 6 with a remainder of 354.
Use 6 as the next digit of our solution. 
Result so far: 109433.6
If we subtract 2916 from 3270, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 10:
The number 486 fits into 3540 7 times, leaving a remainder of 138.
The next digit of our result is 7. 
Result so far: 109433.67
Subtracting 3402 from 3540 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 11:
When dividing 1380 by 486, we get 2 with a remainder of 408.
Write down 2 as next digit of the result. 
Result so far: 109433.672
The remainder is 408 after subtracting 972 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 12:
4080 divided by 486 is 8 with a remainder of 192.
The next digit of our result is 8. 
Result so far: 109433.6728
If we subtract 3888 from 4080, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 13:
486 goes into 1920 3 times with a remainder of 462.
The number 3 becomes the next digit in our result. 
Result so far: 109433.67283
Subtracting 1458 from 1920 leaves us with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 14:
The number 486 fits into 4620 9 times, leaving a remainder of 246.
Record the quotient 9 as the next digit in the result. 
Result so far: 109433.672839
Subtract 4374 from 4620 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 15:
The number 486 fits into 2460 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 109433.6728395
Subtracting 2430 from 2460 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 16:
486 goes into 300 0 times with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 109433.6728395
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 109433.6728395 with a remaining 3e-07.
