We divide 90780678 by 590
The aim is to understand the frequency of 590 in 90780678.

Let's proceed to step 1:
The number 590 fits into 9 0 times, leaving 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 (0) from the dividend, add it to 9, then carry on: 90 / 590

Advancing to step 2:
When dividing 90 by 590, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Fetch the next digit (7) from the dividend, attach it to 90 and continue: 907 / 590

Going ahead to step 3:
590 can be fit into 907 1 times, resulting in a remainder of 317.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 590 from 907 leaves us with 317.
Bring next digit (8) of the dividend behind the 317 and repeat the process: 3178 / 590

Moving on to step 4:
If we divide 3178 by 590, we get 5 and a remainder of 228.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2950 from 3178 to get 228.
Bring next digit (0) of the dividend behind the 228 and repeat the process: 2280 / 590

Going ahead to step 5:
590 goes into 2280 3 times with a remainder of 510.
The next digit of our result is 3. 
Result so far: 153.0
The remainder is 510 after subtracting 1770 from 2280.
Include the next digit (6) from the dividend after 510, then repeat: 5106 / 590

Step 6:
590 goes into 5106 8 times with a remainder of 386.
Use 8 as the next digit of our solution. 
Result so far: 1538.0
Subtract 4720 from 5106 to get 386.
Take the next digit (7) from the dividend and append it to 386, then repeat: 3867 / 590

Advancing to step 7:
590 goes into 3867 6 times with a remainder of 327.
Put 6 as the next digit of the answer. 
Result so far: 15386.0
Subtract 3540 from 3867 to get 327.
Bring next digit (8) of the dividend behind the 327 and repeat the process: 3278 / 590

Moving on to step 8:
When dividing 3278 by 590, we get 5 with a remainder of 328.
Put 5 as the next digit of the answer. 
Result so far: 153865.0
If we subtract 2950 from 3278, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 9:
590 can be fit into 3280 5 times, resulting in a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 153865.5
Subtracting 2950 from 3280 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 10:
590 can be fit into 3300 5 times, resulting in a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 153865.55
Subtract 2950 from 3300 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The quotient of the division is 153865.55, and the remainder is 0.35.
