We look at the division of 75496766 by 577 
The aim is to understand the frequency of 577 in 75496766.

Let's proceed to step 1:
7 divided by 577 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 577

Step 2:
75 divided by 577 is 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Include the next digit (4) from the dividend after 75, then repeat: 754 / 577

Moving on to step 3:
When dividing 754 by 577, we get 1 with a remainder of 177.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 177 after subtracting 577 from 754.
Take the next digit (9) from the dividend and append it to 177, then repeat: 1779 / 577

On to step 4:
If we divide 1779 by 577, we get 3 and a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 48 after subtracting 1731 from 1779.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 577

Moving on to step 5:
577 can be fit into 486 0 times, resulting in a remainder of 486.
Use 0 as the next digit of our solution. 
Result so far: 130.0
If we subtract 0 from 486, we get 486.
Take the next digit (7) from the dividend and append it to 486, then repeat: 4867 / 577

Going ahead to step 6:
If we divide 4867 by 577, we get 8 and a remainder of 251.
Use 8 as the next digit of our solution. 
Result so far: 1308.0
If we take 4616 away from 4867, we end up with 251.
Take the next digit (6) from the dividend and append it to 251, then repeat: 2516 / 577

Going ahead to step 7:
When dividing 2516 by 577, we get 4 with a remainder of 208.
Record the quotient 4 as the next digit in the result. 
Result so far: 13084.0
Subtract 2308 from 2516 to get 208.
Append the next digit (6) from the dividend to 208 and continue with: 2086 / 577

Let's proceed to step 8:
577 goes into 2086 3 times with a remainder of 355.
Write down 3 as next digit of the result. 
Result so far: 130843.0
If we take 1731 away from 2086, we end up with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 9:
When dividing 3550 by 577, we get 6 with a remainder of 88.
Use 6 as the next digit of our solution. 
Result so far: 130843.6
The remainder is 88 after subtracting 3462 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 10:
577 goes into 880 1 times with a remainder of 303.
Put 1 as the next digit of the answer. 
Result so far: 130843.61
The remainder is 303 after subtracting 577 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Moving on to step 11:
3030 divided by 577 is 5 with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 130843.615
Subtract 2885 from 3030 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 12:
When dividing 1450 by 577, we get 2 with a remainder of 296.
Record the quotient 2 as the next digit in the result. 
Result so far: 130843.6152
Subtracting 1154 from 1450 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 13:
577 goes into 2960 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 130843.61525
The remainder is 75 after subtracting 2885 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
The number 577 fits into 750 1 times, leaving a remainder of 173.
Record the quotient 1 as the next digit in the result. 
Result so far: 130843.615251
The remainder is 173 after subtracting 577 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 15:
577 can be fit into 1730 2 times, resulting in a remainder of 576.
The number 2 becomes the next digit in our result. 
Result so far: 130843.6152512
Subtracting 1154 from 1730 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 16:
When dividing 5760 by 577, we get 9 with a remainder of 567.
Write down 9 as next digit of the result. 
Result so far: 130843.61525129
If we subtract 5193 from 5760, we get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

The final result is 130843.61525129 with a remainder of 5.67e-07.
