We're dividing 15143115 by 860 
The aim is to understand the frequency of 860 in 15143115.

Moving on to step 1:
1 divided by 860 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 860

On to step 2:
When dividing 15 by 860, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 860

Let's proceed to step 3:
151 divided by 860 is 0 with a remainder of 151.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 151, we get 151.
Include the next digit (4) from the dividend after 151, then repeat: 1514 / 860

Advancing to step 4:
When dividing 1514 by 860, we get 1 with a remainder of 654.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 860 from 1514 to get 654.
Append the next digit (3) from the dividend to 654 and continue with: 6543 / 860

Moving on to step 5:
If we divide 6543 by 860, we get 7 and a remainder of 523.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 6020 from 6543, we get 523.
Include the next digit (1) from the dividend after 523, then repeat: 5231 / 860

Step 6:
860 can be fit into 5231 6 times, resulting in a remainder of 71.
Put 6 as the next digit of the answer. 
Result so far: 176.0
The remainder is 71 after subtracting 5160 from 5231.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 860

On to step 7:
If we divide 711 by 860, we get 0 and a remainder of 711.
The number 0 becomes the next digit in our result. 
Result so far: 1760.0
If we subtract 0 from 711, we get 711.
Grab the next digit (5) from the dividend, add it to 711, then carry on: 7115 / 860

Step 8:
860 can be fit into 7115 8 times, resulting in a remainder of 235.
Record the quotient 8 as the next digit in the result. 
Result so far: 17608.0
If we subtract 6880 from 7115, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 9:
860 goes into 2350 2 times with a remainder of 630.
The number 2 becomes the next digit in our result. 
Result so far: 17608.2
The remainder is 630 after subtracting 1720 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 10:
6300 divided by 860 is 7 with a remainder of 280.
Write down 7 as next digit of the result. 
Result so far: 17608.27
If we subtract 6020 from 6300, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
If we divide 2800 by 860, we get 3 and a remainder of 220.
Record the quotient 3 as the next digit in the result. 
Result so far: 17608.273
Deduct 2580 from 2800 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 12:
860 can be fit into 2200 2 times, resulting in a remainder of 480.
Record the quotient 2 as the next digit in the result. 
Result so far: 17608.2732
The remainder is 480 after subtracting 1720 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 13:
If we divide 4800 by 860, we get 5 and a remainder of 500.
Put 5 as the next digit of the answer. 
Result so far: 17608.27325
Deduct 4300 from 4800 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 14:
860 goes into 5000 5 times with a remainder of 700.
The next digit of our result is 5. 
Result so far: 17608.273255
Deduct 4300 from 5000 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Our division results in 17608.273255 with a remaining 7e-05.
