Let's divide 27180347 by 870
The aim is to understand the frequency of 870 in 27180347.

On to step 1:
870 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 870

Going ahead to step 2:
If we divide 27 by 870, we get 0 and a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 870

Going ahead to step 3:
The number 870 fits into 271 0 times, leaving a remainder of 271.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 271 to get 271.
Grab the next digit (8) from the dividend, add it to 271, then carry on: 2718 / 870

On to step 4:
When dividing 2718 by 870, we get 3 with a remainder of 108.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 2610 away from 2718, we end up with 108.
Grab the next digit (0) from the dividend, add it to 108, then carry on: 1080 / 870

Let's proceed to step 5:
If we divide 1080 by 870, we get 1 and a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 870 from 1080, we get 210.
Grab the next digit (3) from the dividend, add it to 210, then carry on: 2103 / 870

On to step 6:
870 can be fit into 2103 2 times, resulting in a remainder of 363.
The next digit of our result is 2. 
Result so far: 312.0
If we subtract 1740 from 2103, we get 363.
Take the next digit (4) from the dividend and append it to 363, then repeat: 3634 / 870

Advancing to step 7:
870 goes into 3634 4 times with a remainder of 154.
Put 4 as the next digit of the answer. 
Result so far: 3124.0
The remainder is 154 after subtracting 3480 from 3634.
Include the next digit (7) from the dividend after 154, then repeat: 1547 / 870

Advancing to step 8:
870 can be fit into 1547 1 times, resulting in a remainder of 677.
Put 1 as the next digit of the answer. 
Result so far: 31241.0
The remainder is 677 after subtracting 870 from 1547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

On to step 9:
870 goes into 6770 7 times with a remainder of 680.
Record the quotient 7 as the next digit in the result. 
Result so far: 31241.7
If we subtract 6090 from 6770, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 10:
The number 870 fits into 6800 7 times, leaving a remainder of 710.
The number 7 becomes the next digit in our result. 
Result so far: 31241.77
Subtracting 6090 from 6800 leaves us with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

The final outcome is 31241.77, with a leftover of 0.71.
