We're dividing 878848 by 985 
The aim is to understand the frequency of 985 in 878848.

Step 1:
If we divide 8 by 985, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 985

Moving on to step 2:
The number 985 fits into 87 0 times, leaving a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Include the next digit (8) from the dividend after 87, then repeat: 878 / 985

Going ahead to step 3:
985 can be fit into 878 0 times, resulting in a remainder of 878.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 878 to get 878.
Bring next digit (8) of the dividend behind the 878 and repeat the process: 8788 / 985

Moving on to step 4:
If we divide 8788 by 985, we get 8 and a remainder of 908.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7880 from 8788 to get 908.
Append the next digit (4) from the dividend to 908 and continue with: 9084 / 985

Step 5:
If we divide 9084 by 985, we get 9 and a remainder of 219.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtract 8865 from 9084 to get 219.
Fetch the next digit (8) from the dividend, attach it to 219 and continue: 2198 / 985

On to step 6:
When dividing 2198 by 985, we get 2 with a remainder of 228.
The next digit of our result is 2. 
Result so far: 892.0
The remainder is 228 after subtracting 1970 from 2198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 7:
The number 985 fits into 2280 2 times, leaving a remainder of 310.
The number 2 becomes the next digit in our result. 
Result so far: 892.2
Subtract 1970 from 2280 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 8:
When dividing 3100 by 985, we get 3 with a remainder of 145.
Write down 3 as next digit of the result. 
Result so far: 892.23
If we take 2955 away from 3100, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 9:
985 goes into 1450 1 times with a remainder of 465.
The number 1 becomes the next digit in our result. 
Result so far: 892.231
Subtracting 985 from 1450 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 10:
985 goes into 4650 4 times with a remainder of 710.
Put 4 as the next digit of the answer. 
Result so far: 892.2314
If we subtract 3940 from 4650, we get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Advancing to step 11:
7100 divided by 985 is 7 with a remainder of 205.
Put 7 as the next digit of the answer. 
Result so far: 892.23147
The remainder is 205 after subtracting 6895 from 7100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 12:
If we divide 2050 by 985, we get 2 and a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 892.231472
Subtracting 1970 from 2050 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
If we divide 800 by 985, we get 0 and a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 892.231472
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Let's proceed to step 14:
985 can be fit into 8000 8 times, resulting in a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 892.23147208
Subtracting 7880 from 8000 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 892.23147208, with a leftover of 1.2e-07.
