We're dividing 57564374 by 881 
The aim is to understand the frequency of 881 in 57564374.

On to step 1:
When dividing 5 by 881, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 881

Let's proceed to step 2:
881 can be fit into 57 0 times, resulting in a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 881

Advancing to step 3:
The number 881 fits into 575 0 times, leaving a remainder of 575.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 575 after subtracting 0 from 575.
Bring next digit (6) of the dividend behind the 575 and repeat the process: 5756 / 881

Advancing to step 4:
881 can be fit into 5756 6 times, resulting in a remainder of 470.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 5286 from 5756, we get 470.
Include the next digit (4) from the dividend after 470, then repeat: 4704 / 881

Let's proceed to step 5:
4704 divided by 881 is 5 with a remainder of 299.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtracting 4405 from 4704 leaves us with 299.
Grab the next digit (3) from the dividend, add it to 299, then carry on: 2993 / 881

Advancing to step 6:
881 can be fit into 2993 3 times, resulting in a remainder of 350.
Put 3 as the next digit of the answer. 
Result so far: 653.0
Subtract 2643 from 2993 to get 350.
Include the next digit (7) from the dividend after 350, then repeat: 3507 / 881

Step 7:
When dividing 3507 by 881, we get 3 with a remainder of 864.
Write down 3 as next digit of the result. 
Result so far: 6533.0
Subtracting 2643 from 3507 leaves us with 864.
Fetch the next digit (4) from the dividend, attach it to 864 and continue: 8644 / 881

On to step 8:
The number 881 fits into 8644 9 times, leaving a remainder of 715.
Write down 9 as next digit of the result. 
Result so far: 65339.0
Subtracting 7929 from 8644 leaves us with 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

On to step 9:
7150 divided by 881 is 8 with a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 65339.8
If we take 7048 away from 7150, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
When dividing 1020 by 881, we get 1 with a remainder of 139.
Use 1 as the next digit of our solution. 
Result so far: 65339.81
The remainder is 139 after subtracting 881 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 11:
The number 881 fits into 1390 1 times, leaving a remainder of 509.
Use 1 as the next digit of our solution. 
Result so far: 65339.811
The remainder is 509 after subtracting 881 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

The final result is 65339.811 with a remainder of 0.0509.
