We look at the division of 77791740 by 585 
The aim is to understand the frequency of 585 in 77791740.

Going ahead to step 1:
585 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 585

Going ahead to step 2:
585 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 585

On to step 3:
777 divided by 585 is 1 with a remainder of 192.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 585 from 777, we get 192.
Bring next digit (9) of the dividend behind the 192 and repeat the process: 1929 / 585

On to step 4:
If we divide 1929 by 585, we get 3 and a remainder of 174.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1755 from 1929, we get 174.
Grab the next digit (1) from the dividend, add it to 174, then carry on: 1741 / 585

Going ahead to step 5:
The number 585 fits into 1741 2 times, leaving a remainder of 571.
Use 2 as the next digit of our solution. 
Result so far: 132.0
If we take 1170 away from 1741, we end up with 571.
Bring next digit (7) of the dividend behind the 571 and repeat the process: 5717 / 585

Moving on to step 6:
When dividing 5717 by 585, we get 9 with a remainder of 452.
Put 9 as the next digit of the answer. 
Result so far: 1329.0
Subtract 5265 from 5717 to get 452.
Bring next digit (4) of the dividend behind the 452 and repeat the process: 4524 / 585

Going ahead to step 7:
4524 divided by 585 is 7 with a remainder of 429.
Put 7 as the next digit of the answer. 
Result so far: 13297.0
If we subtract 4095 from 4524, we get 429.
Append the next digit (0) from the dividend to 429 and continue with: 4290 / 585

Step 8:
When dividing 4290 by 585, we get 7 with a remainder of 195.
Write down 7 as next digit of the result. 
Result so far: 132977.0
The remainder is 195 after subtracting 4095 from 4290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 9:
1950 divided by 585 is 3 with a remainder of 195.
Write down 3 as next digit of the result. 
Result so far: 132977.3
The remainder is 195 after subtracting 1755 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 10:
1950 divided by 585 is 3 with a remainder of 195.
Use 3 as the next digit of our solution. 
Result so far: 132977.33
The remainder is 195 after subtracting 1755 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The final outcome is 132977.33, with a leftover of 0.195.
