309764 divided by 53 
The aim is to understand the frequency of 53 in 309764.

On to step 1:
3 divided by 53 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 53

Let's proceed to step 2:
53 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 53

Step 3:
309 divided by 53 is 5 with a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 44 after subtracting 265 from 309.
Append the next digit (7) from the dividend to 44 and continue with: 447 / 53

Advancing to step 4:
If we divide 447 by 53, we get 8 and a remainder of 23.
The next digit of our result is 8. 
Result so far: 58.0
Deduct 424 from 447 and we're left with 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 53

Going ahead to step 5:
53 can be fit into 236 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 584.0
The remainder is 24 after subtracting 212 from 236.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 53

Moving on to step 6:
The number 53 fits into 244 4 times, leaving a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 5844.0
Deduct 212 from 244 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
The number 53 fits into 320 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 5844.6
Deduct 318 from 320 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
The number 53 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 5844.6
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
53 can be fit into 200 3 times, resulting in a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 5844.603
Deduct 159 from 200 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 10:
If we divide 410 by 53, we get 7 and a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 5844.6037
Deduct 371 from 410 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 11:
When dividing 390 by 53, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 5844.60377
The remainder is 19 after subtracting 371 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 5844.60377 with a remainder of 1.9e-05.
