We look at the division of 364849 by 53 
The aim is to understand the frequency of 53 in 364849.

Step 1:
When dividing 3 by 53, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 53

On to step 2:
When dividing 36 by 53, we get 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 53

Going ahead to step 3:
364 divided by 53 is 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 46 after subtracting 318 from 364.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 53

Advancing to step 4:
468 divided by 53 is 8 with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we take 424 away from 468, we end up with 44.
Append the next digit (4) from the dividend to 44 and continue with: 444 / 53

Moving on to step 5:
When dividing 444 by 53, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 688.0
The remainder is 20 after subtracting 424 from 444.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 53

Going ahead to step 6:
53 goes into 209 3 times with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 6883.0
Subtracting 159 from 209 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
53 goes into 500 9 times with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 6883.9
If we subtract 477 from 500, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 8:
If we divide 230 by 53, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 6883.94
Deduct 212 from 230 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
53 can be fit into 180 3 times, resulting in a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 6883.943
Subtract 159 from 180 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
The number 53 fits into 210 3 times, leaving a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 6883.9433
Deduct 159 from 210 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 6883.9433, with a leftover of 0.00051.
