We look at the division of 83883982 by 53 
The aim is to understand the frequency of 53 in 83883982.

Going ahead to step 1:
The number 53 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 53

Step 2:
83 divided by 53 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 30 after subtracting 53 from 83.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 53

Step 3:
The number 53 fits into 308 5 times, leaving a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 265 away from 308, we end up with 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 53

Step 4:
If we divide 438 by 53, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 158.0
If we take 424 away from 438, we end up with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 53

Let's proceed to step 5:
53 goes into 143 2 times with a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 1582.0
Deduct 106 from 143 and we're left with 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 53

Moving on to step 6:
53 can be fit into 379 7 times, resulting in a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 15827.0
If we subtract 371 from 379, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 53

Let's proceed to step 7:
53 can be fit into 88 1 times, resulting in a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 158271.0
Deduct 53 from 88 and we're left with 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 53

On to step 8:
If we divide 352 by 53, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 1582716.0
If we subtract 318 from 352, we 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.

Moving on to step 9:
53 can be fit into 340 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 1582716.6
If we take 318 away from 340, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
If we divide 220 by 53, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1582716.64
Subtracting 212 from 220 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
53 can be fit into 80 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1582716.641
If we subtract 53 from 80, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 12:
The number 53 fits into 270 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 1582716.6415
If we take 265 away from 270, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
If we divide 50 by 53, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1582716.6415
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
53 goes into 500 9 times with a remainder of 23.
The next digit of our result is 9. 
Result so far: 1582716.641509
The remainder is 23 after subtracting 477 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 15:
If we divide 230 by 53, we get 4 and a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 1582716.6415094
Subtracting 212 from 230 leaves us 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.

Let's proceed to step 16:
The number 53 fits into 180 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 1582716.64150943
If we subtract 159 from 180, we 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.

The final outcome is 1582716.64150943, with a leftover of 2.1e-08.
