Let's divide 27087800 by 870
The aim is to understand the frequency of 870 in 27087800.

Let's proceed to step 1:
The number 870 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 870

Moving on to step 2:
870 goes into 27 0 times with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 870

Step 3:
270 divided by 870 is 0 with a remainder of 270.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 270 to get 270.
Bring next digit (8) of the dividend behind the 270 and repeat the process: 2708 / 870

Advancing to step 4:
2708 divided by 870 is 3 with a remainder of 98.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2610 from 2708, we get 98.
Append the next digit (7) from the dividend to 98 and continue with: 987 / 870

Advancing to step 5:
987 divided by 870 is 1 with a remainder of 117.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Deduct 870 from 987 and we're left with 117.
Include the next digit (8) from the dividend after 117, then repeat: 1178 / 870

Step 6:
870 goes into 1178 1 times with a remainder of 308.
The number 1 becomes the next digit in our result. 
Result so far: 311.0
The remainder is 308 after subtracting 870 from 1178.
Take the next digit (0) from the dividend and append it to 308, then repeat: 3080 / 870

Step 7:
870 goes into 3080 3 times with a remainder of 470.
The next digit of our result is 3. 
Result so far: 3113.0
The remainder is 470 after subtracting 2610 from 3080.
Take the next digit (0) from the dividend and append it to 470, then repeat: 4700 / 870

On to step 8:
870 goes into 4700 5 times with a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 31135.0
Deduct 4350 from 4700 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 9:
870 goes into 3500 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 31135.4
Subtract 3480 from 3500 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
870 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 31135.4
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 11:
The number 870 fits into 2000 2 times, leaving a remainder of 260.
Put 2 as the next digit of the answer. 
Result so far: 31135.402
Subtracting 1740 from 2000 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 12:
2600 divided by 870 is 2 with a remainder of 860.
Use 2 as the next digit of our solution. 
Result so far: 31135.4022
If we take 1740 away from 2600, we end up with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

In conclusion, the division gives 31135.4022 with a balance of 0.0086.
