We look at the division of 54087262 by 577 
The aim is to understand the frequency of 577 in 54087262.

Going ahead to step 1:
The number 577 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 577

Advancing to step 2:
54 divided by 577 is 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 577

Moving on to step 3:
577 can be fit into 540 0 times, resulting in a remainder of 540.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 540 leaves us with 540.
Fetch the next digit (8) from the dividend, attach it to 540 and continue: 5408 / 577

On to step 4:
When dividing 5408 by 577, we get 9 with a remainder of 215.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 5193 from 5408 to get 215.
Take the next digit (7) from the dividend and append it to 215, then repeat: 2157 / 577

On to step 5:
577 can be fit into 2157 3 times, resulting in a remainder of 426.
Write down 3 as next digit of the result. 
Result so far: 93.0
The remainder is 426 after subtracting 1731 from 2157.
Append the next digit (2) from the dividend to 426 and continue with: 4262 / 577

On to step 6:
4262 divided by 577 is 7 with a remainder of 223.
Put 7 as the next digit of the answer. 
Result so far: 937.0
Subtract 4039 from 4262 to get 223.
Include the next digit (6) from the dividend after 223, then repeat: 2236 / 577

Let's proceed to step 7:
If we divide 2236 by 577, we get 3 and a remainder of 505.
The next digit of our result is 3. 
Result so far: 9373.0
The remainder is 505 after subtracting 1731 from 2236.
Take the next digit (2) from the dividend and append it to 505, then repeat: 5052 / 577

Advancing to step 8:
If we divide 5052 by 577, we get 8 and a remainder of 436.
Record the quotient 8 as the next digit in the result. 
Result so far: 93738.0
If we take 4616 away from 5052, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 9:
If we divide 4360 by 577, we get 7 and a remainder of 321.
The next digit of our result is 7. 
Result so far: 93738.7
If we take 4039 away from 4360, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 10:
The number 577 fits into 3210 5 times, leaving a remainder of 325.
The next digit of our result is 5. 
Result so far: 93738.75
Deduct 2885 from 3210 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 11:
If we divide 3250 by 577, we get 5 and a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 93738.755
If we take 2885 away from 3250, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

The quotient of the division is 93738.755, and the remainder is 0.0365.
