We're dividing 13089161 by 53 
The aim is to understand the frequency of 53 in 13089161.

On to step 1:
When dividing 1 by 53, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 53

Step 2:
13 divided by 53 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 53

Step 3:
The number 53 fits into 130 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 106 from 130 leaves us with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 53

Going ahead to step 4:
53 can be fit into 248 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 36 after subtracting 212 from 248.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 53

Let's proceed to step 5:
369 divided by 53 is 6 with a remainder of 51.
The next digit of our result is 6. 
Result so far: 246.0
The remainder is 51 after subtracting 318 from 369.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 53

Advancing to step 6:
The number 53 fits into 511 9 times, leaving a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 2469.0
Subtracting 477 from 511 leaves us with 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 53

Step 7:
53 can be fit into 346 6 times, resulting in a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 24696.0
Subtracting 318 from 346 leaves us with 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 53

Advancing to step 8:
53 can be fit into 281 5 times, resulting in a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 246965.0
The remainder is 16 after subtracting 265 from 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
The number 53 fits into 160 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 246965.3
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.

Going ahead to step 10:
10 divided by 53 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 246965.3
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
53 can be fit into 100 1 times, resulting in a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 246965.301
If we subtract 53 from 100, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 12:
If we divide 470 by 53, we get 8 and a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 246965.3018
Subtract 424 from 470 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 13:
If we divide 460 by 53, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 246965.30188
Subtracting 424 from 460 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 246965.30188 with a remainder of 3.6e-05.
