Let's divide 905473 by 51
The aim is to understand the frequency of 51 in 905473.

Going ahead to step 1:
When dividing 9 by 51, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 51

Going ahead to step 2:
51 goes into 90 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 51 from 90 to get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 51

Step 3:
51 goes into 395 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 357 from 395 leaves us with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 51

Going ahead to step 4:
The number 51 fits into 384 7 times, leaving a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 177.0
Deduct 357 from 384 and we're left with 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 51

Moving on to step 5:
277 divided by 51 is 5 with a remainder of 22.
The next digit of our result is 5. 
Result so far: 1775.0
Subtract 255 from 277 to get 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 51

Moving on to step 6:
51 can be fit into 223 4 times, resulting in a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 17754.0
If we take 204 away from 223, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
The number 51 fits into 190 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 17754.3
Subtracting 153 from 190 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
The number 51 fits into 370 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 17754.37
Deduct 357 from 370 and we're left 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 9:
When dividing 130 by 51, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 17754.372
If we take 102 away from 130, 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.

Let's proceed to step 10:
When dividing 280 by 51, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 17754.3725
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
250 divided by 51 is 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 17754.37254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
When dividing 460 by 51, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 17754.372549
Deduct 459 from 460 and we're left 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.

Advancing to step 13:
51 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 17754.372549
Subtracting 0 from 10 leaves us 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 14:
100 divided by 51 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 17754.37254901
Deduct 51 from 100 and we're left 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.

The final result is 17754.37254901 with a remainder of 4.9e-08.
