Let's divide 98827775 by 581
The aim is to understand the frequency of 581 in 98827775.

On to step 1:
If we divide 9 by 581, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 581

Moving on to step 2:
98 divided by 581 is 0 with a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Bring next digit (8) of the dividend behind the 98 and repeat the process: 988 / 581

Advancing to step 3:
The number 581 fits into 988 1 times, leaving a remainder of 407.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 581 from 988 leaves us with 407.
Append the next digit (2) from the dividend to 407 and continue with: 4072 / 581

Going ahead to step 4:
If we divide 4072 by 581, we get 7 and a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 4067 from 4072 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 581

Moving on to step 5:
If we divide 57 by 581, we get 0 and a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Deduct 0 from 57 and we're left with 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 581

On to step 6:
The number 581 fits into 577 0 times, leaving a remainder of 577.
The next digit of our result is 0. 
Result so far: 1700.0
The remainder is 577 after subtracting 0 from 577.
Append the next digit (7) from the dividend to 577 and continue with: 5777 / 581

Advancing to step 7:
If we divide 5777 by 581, we get 9 and a remainder of 548.
Use 9 as the next digit of our solution. 
Result so far: 17009.0
If we subtract 5229 from 5777, we get 548.
Bring next digit (5) of the dividend behind the 548 and repeat the process: 5485 / 581

On to step 8:
581 can be fit into 5485 9 times, resulting in a remainder of 256.
Use 9 as the next digit of our solution. 
Result so far: 170099.0
If we take 5229 away from 5485, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 9:
581 goes into 2560 4 times with a remainder of 236.
Put 4 as the next digit of the answer. 
Result so far: 170099.4
If we subtract 2324 from 2560, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 10:
581 can be fit into 2360 4 times, resulting in a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 170099.44
Deduct 2324 from 2360 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 170099.44, and the remainder is 0.036.
