9345863 ÷ 881 
The aim is to understand the frequency of 881 in 9345863.

Step 1:
881 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 881

Advancing to step 2:
881 can be fit into 93 0 times, resulting in a remainder of 93.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 93 after subtracting 0 from 93.
Bring next digit (4) of the dividend behind the 93 and repeat the process: 934 / 881

Let's proceed to step 3:
The number 881 fits into 934 1 times, leaving a remainder of 53.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 53 after subtracting 881 from 934.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 881

Advancing to step 4:
881 can be fit into 535 0 times, resulting in a remainder of 535.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 535 and we're left with 535.
Append the next digit (8) from the dividend to 535 and continue with: 5358 / 881

Let's proceed to step 5:
The number 881 fits into 5358 6 times, leaving a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtract 5286 from 5358 to get 72.
Fetch the next digit (6) from the dividend, attach it to 72 and continue: 726 / 881

On to step 6:
If we divide 726 by 881, we get 0 and a remainder of 726.
Record the quotient 0 as the next digit in the result. 
Result so far: 1060.0
Subtracting 0 from 726 leaves us with 726.
Take the next digit (3) from the dividend and append it to 726, then repeat: 7263 / 881

Going ahead to step 7:
881 can be fit into 7263 8 times, resulting in a remainder of 215.
The number 8 becomes the next digit in our result. 
Result so far: 10608.0
If we subtract 7048 from 7263, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 8:
When dividing 2150 by 881, we get 2 with a remainder of 388.
Write down 2 as next digit of the result. 
Result so far: 10608.2
Subtract 1762 from 2150 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 9:
3880 divided by 881 is 4 with a remainder of 356.
The next digit of our result is 4. 
Result so far: 10608.24
The remainder is 356 after subtracting 3524 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 10:
881 can be fit into 3560 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 10608.244
If we subtract 3524 from 3560, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 10608.244 with a remainder of 0.0036.
