We're dividing 90508432 by 757 
The aim is to understand the frequency of 757 in 90508432.

On to step 1:
When dividing 9 by 757, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 757

Moving on to step 2:
The number 757 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Take the next digit (5) from the dividend and append it to 90, then repeat: 905 / 757

Moving on to step 3:
The number 757 fits into 905 1 times, leaving a remainder of 148.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 757 from 905, we get 148.
Fetch the next digit (0) from the dividend, attach it to 148 and continue: 1480 / 757

On to step 4:
757 goes into 1480 1 times with a remainder of 723.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 757 from 1480 to get 723.
Fetch the next digit (8) from the dividend, attach it to 723 and continue: 7238 / 757

Advancing to step 5:
If we divide 7238 by 757, we get 9 and a remainder of 425.
Put 9 as the next digit of the answer. 
Result so far: 119.0
If we subtract 6813 from 7238, we get 425.
Bring next digit (4) of the dividend behind the 425 and repeat the process: 4254 / 757

Moving on to step 6:
If we divide 4254 by 757, we get 5 and a remainder of 469.
Put 5 as the next digit of the answer. 
Result so far: 1195.0
If we subtract 3785 from 4254, we get 469.
Include the next digit (3) from the dividend after 469, then repeat: 4693 / 757

Let's proceed to step 7:
757 goes into 4693 6 times with a remainder of 151.
Use 6 as the next digit of our solution. 
Result so far: 11956.0
Subtracting 4542 from 4693 leaves us with 151.
Take the next digit (2) from the dividend and append it to 151, then repeat: 1512 / 757

On to step 8:
757 can be fit into 1512 1 times, resulting in a remainder of 755.
The number 1 becomes the next digit in our result. 
Result so far: 119561.0
If we take 757 away from 1512, we end up with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Moving on to step 9:
7550 divided by 757 is 9 with a remainder of 737.
The number 9 becomes the next digit in our result. 
Result so far: 119561.9
Subtract 6813 from 7550 to get 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Moving on to step 10:
7370 divided by 757 is 9 with a remainder of 557.
The number 9 becomes the next digit in our result. 
Result so far: 119561.99
Subtracting 6813 from 7370 leaves us with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

The final result is 119561.99 with a remainder of 0.557.
