We look at the division of 9130439 by 485 
The aim is to understand the frequency of 485 in 9130439.

On to step 1:
When dividing 9 by 485, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 485

Step 2:
The number 485 fits into 91 0 times, leaving a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 485

Step 3:
913 divided by 485 is 1 with a remainder of 428.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 485 from 913 and we're left with 428.
Bring next digit (0) of the dividend behind the 428 and repeat the process: 4280 / 485

Going ahead to step 4:
4280 divided by 485 is 8 with a remainder of 400.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 3880 from 4280 to get 400.
Take the next digit (4) from the dividend and append it to 400, then repeat: 4004 / 485

Step 5:
If we divide 4004 by 485, we get 8 and a remainder of 124.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
Subtracting 3880 from 4004 leaves us with 124.
Take the next digit (3) from the dividend and append it to 124, then repeat: 1243 / 485

Let's proceed to step 6:
485 goes into 1243 2 times with a remainder of 273.
The next digit of our result is 2. 
Result so far: 1882.0
The remainder is 273 after subtracting 970 from 1243.
Bring next digit (9) of the dividend behind the 273 and repeat the process: 2739 / 485

Going ahead to step 7:
When dividing 2739 by 485, we get 5 with a remainder of 314.
The next digit of our result is 5. 
Result so far: 18825.0
The remainder is 314 after subtracting 2425 from 2739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 8:
The number 485 fits into 3140 6 times, leaving a remainder of 230.
Record the quotient 6 as the next digit in the result. 
Result so far: 18825.6
Subtracting 2910 from 3140 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 9:
2300 divided by 485 is 4 with a remainder of 360.
The next digit of our result is 4. 
Result so far: 18825.64
Subtracting 1940 from 2300 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
485 can be fit into 3600 7 times, resulting in a remainder of 205.
Put 7 as the next digit of the answer. 
Result so far: 18825.647
Deduct 3395 from 3600 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 11:
485 can be fit into 2050 4 times, resulting in a remainder of 110.
Record the quotient 4 as the next digit in the result. 
Result so far: 18825.6474
The remainder is 110 after subtracting 1940 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 12:
485 can be fit into 1100 2 times, resulting in a remainder of 130.
The number 2 becomes the next digit in our result. 
Result so far: 18825.64742
Deduct 970 from 1100 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 13:
The number 485 fits into 1300 2 times, leaving a remainder of 330.
Write down 2 as next digit of the result. 
Result so far: 18825.647422
Subtract 970 from 1300 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

In conclusion, the division gives 18825.647422 with a balance of 3.3e-05.
