We look at the division of 81768 by 53 
The aim is to understand the frequency of 53 in 81768.

Let's proceed to step 1:
8 divided by 53 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 53

Step 2:
If we divide 81 by 53, we get 1 and a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 53 from 81, we get 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 53

Moving on to step 3:
53 can be fit into 287 5 times, resulting in a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 22 after subtracting 265 from 287.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 53

Step 4:
226 divided by 53 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
If we take 212 away from 226, we end up with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 53

Moving on to step 5:
If we divide 148 by 53, we get 2 and a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 1542.0
Subtract 106 from 148 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 6:
53 goes into 420 7 times with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 1542.7
Subtract 371 from 420 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
When dividing 490 by 53, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 1542.79
Subtracting 477 from 490 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
When dividing 130 by 53, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 1542.792
If we subtract 106 from 130, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 53, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 1542.7924
If we take 212 away from 240, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
When dividing 280 by 53, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 1542.79245
Deduct 265 from 280 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
The number 53 fits into 150 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 1542.792452
Deduct 106 from 150 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
The number 53 fits into 440 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1542.7924528
If we take 424 away from 440, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
When dividing 160 by 53, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1542.79245283
If we take 159 away from 160, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 1542.79245283 and a remainder of 1e-09.
