We divide 87125338 by 577
The aim is to understand the frequency of 577 in 87125338.

Moving on to step 1:
The number 577 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 577

Advancing to step 2:
577 goes into 87 0 times with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Grab the next digit (1) from the dividend, add it to 87, then carry on: 871 / 577

Advancing to step 3:
When dividing 871 by 577, we get 1 with a remainder of 294.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 577 away from 871, we end up with 294.
Fetch the next digit (2) from the dividend, attach it to 294 and continue: 2942 / 577

On to step 4:
577 can be fit into 2942 5 times, resulting in a remainder of 57.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 2885 from 2942 to get 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 577

Let's proceed to step 5:
When dividing 575 by 577, we get 0 with a remainder of 575.
Write down 0 as next digit of the result. 
Result so far: 150.0
If we take 0 away from 575, we end up with 575.
Bring next digit (3) of the dividend behind the 575 and repeat the process: 5753 / 577

Let's proceed to step 6:
If we divide 5753 by 577, we get 9 and a remainder of 560.
Write down 9 as next digit of the result. 
Result so far: 1509.0
If we take 5193 away from 5753, we end up with 560.
Take the next digit (3) from the dividend and append it to 560, then repeat: 5603 / 577

Going ahead to step 7:
5603 divided by 577 is 9 with a remainder of 410.
Record the quotient 9 as the next digit in the result. 
Result so far: 15099.0
If we subtract 5193 from 5603, we get 410.
Include the next digit (8) from the dividend after 410, then repeat: 4108 / 577

Advancing to step 8:
The number 577 fits into 4108 7 times, leaving a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 150997.0
If we subtract 4039 from 4108, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 9:
The number 577 fits into 690 1 times, leaving a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 150997.1
Subtract 577 from 690 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 10:
When dividing 1130 by 577, we get 1 with a remainder of 553.
Write down 1 as next digit of the result. 
Result so far: 150997.11
The remainder is 553 after subtracting 577 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

The quotient of the division is 150997.11, and the remainder is 0.553.
