520475 divided by 51 
The aim is to understand the frequency of 51 in 520475.

Going ahead to step 1:
The number 51 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 51

Going ahead to step 2:
51 can be fit into 52 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 51 from 52.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 51

Let's proceed to step 3:
The number 51 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 10 and we're left with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 51

Moving on to step 4:
If we divide 104 by 51, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 2 after subtracting 102 from 104.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 51

Let's proceed to step 5:
51 goes into 27 0 times with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 1020.0
Deduct 0 from 27 and we're left with 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 51

On to step 6:
When dividing 275 by 51, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 10205.0
Deduct 255 from 275 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
51 goes into 200 3 times with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 10205.3
Deduct 153 from 200 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 8:
When dividing 470 by 51, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 10205.39
If we take 459 away from 470, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
When dividing 110 by 51, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 10205.392
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
51 goes into 80 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 10205.3921
If we take 51 away from 80, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 11:
The number 51 fits into 290 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 10205.39215
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
51 can be fit into 350 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 10205.392156
If we take 306 away from 350, we end up 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.

Going ahead to step 13:
51 can be fit into 440 8 times, resulting in a remainder of 32.
The next digit of our result is 8. 
Result so far: 10205.3921568
Deduct 408 from 440 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
When dividing 320 by 51, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 10205.39215686
If we take 306 away from 320, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 10205.39215686 with a balance of 1.4e-08.
