We're dividing 21447046 by 53 
The aim is to understand the frequency of 53 in 21447046.

Advancing to step 1:
2 divided by 53 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 53

On to step 2:
21 divided by 53 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 53

Going ahead to step 3:
The number 53 fits into 214 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 2 after subtracting 212 from 214.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 53

Step 4:
53 can be fit into 24 0 times, resulting in a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 24 to get 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 53

Step 5:
53 goes into 247 4 times with a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 404.0
The remainder is 35 after subtracting 212 from 247.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 53

Going ahead to step 6:
The number 53 fits into 350 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 4046.0
If we subtract 318 from 350, we get 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 53

Going ahead to step 7:
The number 53 fits into 324 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 40466.0
If we take 318 away from 324, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 53

Advancing to step 8:
66 divided by 53 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 404661.0
The remainder is 13 after subtracting 53 from 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
53 can be fit into 130 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 404661.2
The remainder is 24 after subtracting 106 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
240 divided by 53 is 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 404661.24
The remainder is 28 after subtracting 212 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
280 divided by 53 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 404661.245
Subtract 265 from 280 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
When dividing 150 by 53, we get 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 404661.2452
The remainder is 44 after subtracting 106 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
53 goes into 440 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 404661.24528
Subtract 424 from 440 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
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: 404661.245283
Subtracting 159 from 160 leaves us 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 15:
The number 53 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 404661.245283
Deduct 0 from 10 and we're left 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.

Let's proceed to step 16:
53 can be fit into 100 1 times, resulting in a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 404661.24528301
Subtract 53 from 100 to 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.

The final result is 404661.24528301 with a remainder of 4.7e-08.
