We're dividing 71515641 by 881 
The aim is to understand the frequency of 881 in 71515641.

Moving on to step 1:
881 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 881

On to step 2:
The number 881 fits into 71 0 times, leaving a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 881

Moving on to step 3:
The number 881 fits into 715 0 times, leaving a remainder of 715.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 715, we end up with 715.
Append the next digit (1) from the dividend to 715 and continue with: 7151 / 881

Moving on to step 4:
When dividing 7151 by 881, we get 8 with a remainder of 103.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 7048 from 7151 and we're left with 103.
Bring next digit (5) of the dividend behind the 103 and repeat the process: 1035 / 881

Let's proceed to step 5:
If we divide 1035 by 881, we get 1 and a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we take 881 away from 1035, we end up with 154.
Take the next digit (6) from the dividend and append it to 154, then repeat: 1546 / 881

Moving on to step 6:
If we divide 1546 by 881, we get 1 and a remainder of 665.
The next digit of our result is 1. 
Result so far: 811.0
If we take 881 away from 1546, we end up with 665.
Fetch the next digit (4) from the dividend, attach it to 665 and continue: 6654 / 881

Advancing to step 7:
When dividing 6654 by 881, we get 7 with a remainder of 487.
The next digit of our result is 7. 
Result so far: 8117.0
Deduct 6167 from 6654 and we're left with 487.
Fetch the next digit (1) from the dividend, attach it to 487 and continue: 4871 / 881

On to step 8:
The number 881 fits into 4871 5 times, leaving a remainder of 466.
Record the quotient 5 as the next digit in the result. 
Result so far: 81175.0
If we take 4405 away from 4871, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Moving on to step 9:
When dividing 4660 by 881, we get 5 with a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 81175.5
The remainder is 255 after subtracting 4405 from 4660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 10:
881 goes into 2550 2 times with a remainder of 788.
The number 2 becomes the next digit in our result. 
Result so far: 81175.52
Subtract 1762 from 2550 to get 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Step 11:
7880 divided by 881 is 8 with a remainder of 832.
The number 8 becomes the next digit in our result. 
Result so far: 81175.528
If we take 7048 away from 7880, we end up with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Let's proceed to step 12:
When dividing 8320 by 881, we get 9 with a remainder of 391.
The next digit of our result is 9. 
Result so far: 81175.5289
Deduct 7929 from 8320 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

On to step 13:
881 goes into 3910 4 times with a remainder of 386.
Record the quotient 4 as the next digit in the result. 
Result so far: 81175.52894
Deduct 3524 from 3910 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 14:
The number 881 fits into 3860 4 times, leaving a remainder of 336.
The number 4 becomes the next digit in our result. 
Result so far: 81175.528944
Subtracting 3524 from 3860 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Our division results in 81175.528944 with a remaining 3.36e-05.
