We look at the division of 4607428 by 506 
The aim is to understand the frequency of 506 in 4607428.

Advancing to step 1:
4 divided by 506 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 506

Let's proceed to step 2:
506 can be fit into 46 0 times, resulting in a remainder of 46.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 46 and we're left with 46.
Grab the next digit (0) from the dividend, add it to 46, then carry on: 460 / 506

Let's proceed to step 3:
460 divided by 506 is 0 with a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 460 to get 460.
Bring next digit (7) of the dividend behind the 460 and repeat the process: 4607 / 506

Going ahead to step 4:
If we divide 4607 by 506, we get 9 and a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 4554 from 4607 to get 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 506

On to step 5:
506 goes into 534 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we subtract 506 from 534, we get 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 506

On to step 6:
506 goes into 282 0 times with a remainder of 282.
Use 0 as the next digit of our solution. 
Result so far: 910.0
The remainder is 282 after subtracting 0 from 282.
Bring next digit (8) of the dividend behind the 282 and repeat the process: 2828 / 506

Moving on to step 7:
2828 divided by 506 is 5 with a remainder of 298.
Record the quotient 5 as the next digit in the result. 
Result so far: 9105.0
If we take 2530 away from 2828, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 8:
506 goes into 2980 5 times with a remainder of 450.
The next digit of our result is 5. 
Result so far: 9105.5
Subtract 2530 from 2980 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 9:
The number 506 fits into 4500 8 times, leaving a remainder of 452.
Put 8 as the next digit of the answer. 
Result so far: 9105.58
Deduct 4048 from 4500 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 10:
506 can be fit into 4520 8 times, resulting in a remainder of 472.
The number 8 becomes the next digit in our result. 
Result so far: 9105.588
The remainder is 472 after subtracting 4048 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

The final outcome is 9105.588, with a leftover of 0.0472.
