We divide 78565005 by 861
The aim is to understand the frequency of 861 in 78565005.

Going ahead to step 1:
The number 861 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 861

Advancing to step 2:
78 divided by 861 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 861

Step 3:
785 divided by 861 is 0 with a remainder of 785.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 785 leaves us with 785.
Bring next digit (6) of the dividend behind the 785 and repeat the process: 7856 / 861

Going ahead to step 4:
If we divide 7856 by 861, we get 9 and a remainder of 107.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 7749 from 7856 leaves us with 107.
Bring next digit (5) of the dividend behind the 107 and repeat the process: 1075 / 861

On to step 5:
1075 divided by 861 is 1 with a remainder of 214.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we take 861 away from 1075, we end up with 214.
Bring next digit (0) of the dividend behind the 214 and repeat the process: 2140 / 861

On to step 6:
When dividing 2140 by 861, we get 2 with a remainder of 418.
Write down 2 as next digit of the result. 
Result so far: 912.0
The remainder is 418 after subtracting 1722 from 2140.
Bring next digit (0) of the dividend behind the 418 and repeat the process: 4180 / 861

Moving on to step 7:
861 goes into 4180 4 times with a remainder of 736.
Use 4 as the next digit of our solution. 
Result so far: 9124.0
If we take 3444 away from 4180, we end up with 736.
Append the next digit (5) from the dividend to 736 and continue with: 7365 / 861

Going ahead to step 8:
861 goes into 7365 8 times with a remainder of 477.
The next digit of our result is 8. 
Result so far: 91248.0
Subtracting 6888 from 7365 leaves us with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Step 9:
The number 861 fits into 4770 5 times, leaving a remainder of 465.
Put 5 as the next digit of the answer. 
Result so far: 91248.5
Subtract 4305 from 4770 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 10:
4650 divided by 861 is 5 with a remainder of 345.
Record the quotient 5 as the next digit in the result. 
Result so far: 91248.55
Subtract 4305 from 4650 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The final result is 91248.55 with a remainder of 0.345.
