75545860 ÷ 577 
The aim is to understand the frequency of 577 in 75545860.

Let's proceed to step 1:
The number 577 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 577

Step 2:
When dividing 75 by 577, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Append the next digit (5) from the dividend to 75 and continue with: 755 / 577

Going ahead to step 3:
577 goes into 755 1 times with a remainder of 178.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 577 from 755 and we're left with 178.
Include the next digit (4) from the dividend after 178, then repeat: 1784 / 577

On to step 4:
577 can be fit into 1784 3 times, resulting in a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1731 from 1784 leaves us with 53.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 577

Let's proceed to step 5:
If we divide 535 by 577, we get 0 and a remainder of 535.
Use 0 as the next digit of our solution. 
Result so far: 130.0
Subtracting 0 from 535 leaves us with 535.
Append the next digit (8) from the dividend to 535 and continue with: 5358 / 577

On to step 6:
If we divide 5358 by 577, we get 9 and a remainder of 165.
Use 9 as the next digit of our solution. 
Result so far: 1309.0
If we take 5193 away from 5358, we end up with 165.
Include the next digit (6) from the dividend after 165, then repeat: 1656 / 577

Let's proceed to step 7:
The number 577 fits into 1656 2 times, leaving a remainder of 502.
Use 2 as the next digit of our solution. 
Result so far: 13092.0
If we take 1154 away from 1656, we end up with 502.
Fetch the next digit (0) from the dividend, attach it to 502 and continue: 5020 / 577

Going ahead to step 8:
5020 divided by 577 is 8 with a remainder of 404.
Record the quotient 8 as the next digit in the result. 
Result so far: 130928.0
Deduct 4616 from 5020 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 9:
577 can be fit into 4040 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 130928.7
If we take 4039 away from 4040, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
577 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 130928.7
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
100 divided by 577 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 130928.7
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 130928.7 with a remaining 0.01.
