We look at the division of 71291083 by 885 
The aim is to understand the frequency of 885 in 71291083.

Moving on to step 1:
885 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 885

On to step 2:
If we divide 71 by 885, we get 0 and a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Append the next digit (2) from the dividend to 71 and continue with: 712 / 885

Going ahead to step 3:
712 divided by 885 is 0 with a remainder of 712.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 712, we end up with 712.
Grab the next digit (9) from the dividend, add it to 712, then carry on: 7129 / 885

Advancing to step 4:
885 can be fit into 7129 8 times, resulting in a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 49 after subtracting 7080 from 7129.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 885

Moving on to step 5:
When dividing 491 by 885, we get 0 with a remainder of 491.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we subtract 0 from 491, we get 491.
Include the next digit (0) from the dividend after 491, then repeat: 4910 / 885

Going ahead to step 6:
The number 885 fits into 4910 5 times, leaving a remainder of 485.
The number 5 becomes the next digit in our result. 
Result so far: 805.0
If we subtract 4425 from 4910, we get 485.
Bring next digit (8) of the dividend behind the 485 and repeat the process: 4858 / 885

Let's proceed to step 7:
885 can be fit into 4858 5 times, resulting in a remainder of 433.
Put 5 as the next digit of the answer. 
Result so far: 8055.0
Deduct 4425 from 4858 and we're left with 433.
Take the next digit (3) from the dividend and append it to 433, then repeat: 4333 / 885

Let's proceed to step 8:
4333 divided by 885 is 4 with a remainder of 793.
Record the quotient 4 as the next digit in the result. 
Result so far: 80554.0
If we subtract 3540 from 4333, we get 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Advancing to step 9:
When dividing 7930 by 885, we get 8 with a remainder of 850.
The next digit of our result is 8. 
Result so far: 80554.8
The remainder is 850 after subtracting 7080 from 7930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Let's proceed to step 10:
The number 885 fits into 8500 9 times, leaving a remainder of 535.
Use 9 as the next digit of our solution. 
Result so far: 80554.89
The remainder is 535 after subtracting 7965 from 8500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Let's proceed to step 11:
885 goes into 5350 6 times with a remainder of 40.
The next digit of our result is 6. 
Result so far: 80554.896
If we subtract 5310 from 5350, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
885 can be fit into 400 0 times, resulting in a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 80554.896
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
4000 divided by 885 is 4 with a remainder of 460.
The number 4 becomes the next digit in our result. 
Result so far: 80554.89604
If we take 3540 away from 4000, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 14:
When dividing 4600 by 885, we get 5 with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 80554.896045
Subtract 4425 from 4600 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 15:
885 goes into 1750 1 times with a remainder of 865.
Put 1 as the next digit of the answer. 
Result so far: 80554.8960451
The remainder is 865 after subtracting 885 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Advancing to step 16:
The number 885 fits into 8650 9 times, leaving a remainder of 685.
The next digit of our result is 9. 
Result so far: 80554.89604519
The remainder is 685 after subtracting 7965 from 8650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

The quotient of the division is 80554.89604519, and the remainder is 6.85e-07.
