551128 divided by 53 
The aim is to understand the frequency of 53 in 551128.

Going ahead to step 1:
The number 53 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 53

Going ahead to step 2:
53 goes into 55 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we take 53 away from 55, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 53

Going ahead to step 3:
53 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 53

Let's proceed to step 4:
53 can be fit into 211 3 times, resulting in a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 103.0
If we subtract 159 from 211, we get 52.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 53

Step 5:
The number 53 fits into 522 9 times, leaving a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 1039.0
If we take 477 away from 522, we end up with 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 53

Advancing to step 6:
53 goes into 458 8 times with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 10398.0
Deduct 424 from 458 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
If we divide 340 by 53, we get 6 and a remainder of 22.
The next digit of our result is 6. 
Result so far: 10398.6
Deduct 318 from 340 and we're left 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 8:
The number 53 fits into 220 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 10398.64
If we take 212 away from 220, we end up 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.

Going ahead to step 9:
53 can be fit into 80 1 times, resulting in a remainder of 27.
The next digit of our result is 1. 
Result so far: 10398.641
The remainder is 27 after subtracting 53 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
53 goes into 270 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 10398.6415
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 11:
53 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 10398.6415
Subtract 0 from 50 to 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 12:
500 divided by 53 is 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 10398.641509
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.

Going ahead to step 13:
When dividing 230 by 53, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 10398.6415094
The remainder is 18 after subtracting 212 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
180 divided by 53 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 10398.64150943
Deduct 159 from 180 and we're left with 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 result is 10398.64150943 with a remainder of 2.1e-08.
