We're dividing 86896822 by 577 
The aim is to understand the frequency of 577 in 86896822.

Going ahead to step 1:
If we divide 8 by 577, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 577

Advancing to step 2:
The number 577 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (8) from the dividend and append it to 86, then repeat: 868 / 577

Advancing to step 3:
When dividing 868 by 577, we get 1 with a remainder of 291.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 291 after subtracting 577 from 868.
Bring next digit (9) of the dividend behind the 291 and repeat the process: 2919 / 577

Moving on to step 4:
577 goes into 2919 5 times with a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 34 after subtracting 2885 from 2919.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 577

Going ahead to step 5:
346 divided by 577 is 0 with a remainder of 346.
Write down 0 as next digit of the result. 
Result so far: 150.0
If we subtract 0 from 346, we get 346.
Fetch the next digit (8) from the dividend, attach it to 346 and continue: 3468 / 577

Let's proceed to step 6:
577 goes into 3468 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 1506.0
Subtracting 3462 from 3468 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 577

On to step 7:
The number 577 fits into 62 0 times, leaving a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 15060.0
Deduct 0 from 62 and we're left with 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 577

On to step 8:
If we divide 622 by 577, we get 1 and a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 150601.0
If we take 577 away from 622, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
If we divide 450 by 577, we get 0 and a remainder of 450.
Record the quotient 0 as the next digit in the result. 
Result so far: 150601.0
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 10:
4500 divided by 577 is 7 with a remainder of 461.
Put 7 as the next digit of the answer. 
Result so far: 150601.07
If we subtract 4039 from 4500, we get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Step 11:
The number 577 fits into 4610 7 times, leaving a remainder of 571.
Put 7 as the next digit of the answer. 
Result so far: 150601.077
Subtracting 4039 from 4610 leaves us with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Our division results in 150601.077 with a remaining 0.0571.
