85250248 ÷ 855 
The aim is to understand the frequency of 855 in 85250248.

Step 1:
8 divided by 855 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 855

Moving on to step 2:
85 divided by 855 is 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Append the next digit (2) from the dividend to 85 and continue with: 852 / 855

Let's proceed to step 3:
The number 855 fits into 852 0 times, leaving a remainder of 852.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 852 and we're left with 852.
Grab the next digit (5) from the dividend, add it to 852, then carry on: 8525 / 855

Step 4:
If we divide 8525 by 855, we get 9 and a remainder of 830.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 830 after subtracting 7695 from 8525.
Fetch the next digit (0) from the dividend, attach it to 830 and continue: 8300 / 855

On to step 5:
8300 divided by 855 is 9 with a remainder of 605.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtract 7695 from 8300 to get 605.
Take the next digit (2) from the dividend and append it to 605, then repeat: 6052 / 855

Step 6:
When dividing 6052 by 855, we get 7 with a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 997.0
Deduct 5985 from 6052 and we're left with 67.
Bring next digit (4) of the dividend behind the 67 and repeat the process: 674 / 855

Going ahead to step 7:
The number 855 fits into 674 0 times, leaving a remainder of 674.
Write down 0 as next digit of the result. 
Result so far: 9970.0
Subtract 0 from 674 to get 674.
Include the next digit (8) from the dividend after 674, then repeat: 6748 / 855

Moving on to step 8:
When dividing 6748 by 855, we get 7 with a remainder of 763.
Put 7 as the next digit of the answer. 
Result so far: 99707.0
Deduct 5985 from 6748 and we're left with 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

On to step 9:
The number 855 fits into 7630 8 times, leaving a remainder of 790.
The next digit of our result is 8. 
Result so far: 99707.8
Subtracting 6840 from 7630 leaves us with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Advancing to step 10:
7900 divided by 855 is 9 with a remainder of 205.
Put 9 as the next digit of the answer. 
Result so far: 99707.89
If we subtract 7695 from 7900, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 11:
855 goes into 2050 2 times with a remainder of 340.
Write down 2 as next digit of the result. 
Result so far: 99707.892
Subtracting 1710 from 2050 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 12:
The number 855 fits into 3400 3 times, leaving a remainder of 835.
The next digit of our result is 3. 
Result so far: 99707.8923
Subtract 2565 from 3400 to get 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Going ahead to step 13:
If we divide 8350 by 855, we get 9 and a remainder of 655.
Write down 9 as next digit of the result. 
Result so far: 99707.89239
If we take 7695 away from 8350, we end up with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Step 14:
The number 855 fits into 6550 7 times, leaving a remainder of 565.
Record the quotient 7 as the next digit in the result. 
Result so far: 99707.892397
Subtract 5985 from 6550 to get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Let's proceed to step 15:
5650 divided by 855 is 6 with a remainder of 520.
The next digit of our result is 6. 
Result so far: 99707.8923976
The remainder is 520 after subtracting 5130 from 5650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 16:
When dividing 5200 by 855, we get 6 with a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 99707.89239766
Subtract 5130 from 5200 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 99707.89239766 with a remainder of 7e-08.
