We look at the division of 671662 by 53 
The aim is to understand the frequency of 53 in 671662.

Moving on to step 1:
When dividing 6 by 53, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 53

Moving on to step 2:
53 can be fit into 67 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 53 from 67 leaves us with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 53

Let's proceed to step 3:
141 divided by 53 is 2 with a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 106 from 141 leaves us with 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 53

Step 4:
If we divide 356 by 53, we get 6 and a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtracting 318 from 356 leaves us with 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 53

Advancing to step 5:
386 divided by 53 is 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 1267.0
Subtract 371 from 386 to get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 53

Step 6:
53 can be fit into 152 2 times, resulting in a remainder of 46.
The next digit of our result is 2. 
Result so far: 12672.0
Subtract 106 from 152 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.

Moving on to step 7:
53 can be fit into 460 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 12672.8
Subtract 424 from 460 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
If we divide 360 by 53, we get 6 and a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 12672.86
Deduct 318 from 360 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
The number 53 fits into 420 7 times, leaving a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 12672.867
If we take 371 away from 420, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 10:
When dividing 490 by 53, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 12672.8679
If we take 477 away from 490, we end up 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.

Let's proceed to step 11:
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: 12672.86792
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.

Step 12:
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: 12672.867924
Deduct 212 from 240 and we're left 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.

On to step 13:
When dividing 280 by 53, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 12672.8679245
If we take 265 away from 280, we end up 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.

Advancing to step 14:
When dividing 150 by 53, we get 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 12672.86792452
Subtracting 106 from 150 leaves us 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.

After the division, we end up with 12672.86792452 and a remainder of 4.4e-08.
