Let's divide 15014639 by 855
The aim is to understand the frequency of 855 in 15014639.

Moving on to step 1:
855 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 855

Advancing to step 2:
855 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 855

On to step 3:
855 can be fit into 150 0 times, resulting in a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 150 leaves us with 150.
Take the next digit (1) from the dividend and append it to 150, then repeat: 1501 / 855

Going ahead to step 4:
The number 855 fits into 1501 1 times, leaving a remainder of 646.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 855 from 1501 to get 646.
Include the next digit (4) from the dividend after 646, then repeat: 6464 / 855

Going ahead to step 5:
855 goes into 6464 7 times with a remainder of 479.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 5985 from 6464 to get 479.
Grab the next digit (6) from the dividend, add it to 479, then carry on: 4796 / 855

Moving on to step 6:
When dividing 4796 by 855, we get 5 with a remainder of 521.
The number 5 becomes the next digit in our result. 
Result so far: 175.0
If we subtract 4275 from 4796, we get 521.
Grab the next digit (3) from the dividend, add it to 521, then carry on: 5213 / 855

On to step 7:
5213 divided by 855 is 6 with a remainder of 83.
The next digit of our result is 6. 
Result so far: 1756.0
Deduct 5130 from 5213 and we're left with 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 855

Advancing to step 8:
The number 855 fits into 839 0 times, leaving a remainder of 839.
Write down 0 as next digit of the result. 
Result so far: 17560.0
If we take 0 away from 839, we end up with 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8390, and continue the process.

On to step 9:
If we divide 8390 by 855, we get 9 and a remainder of 695.
The number 9 becomes the next digit in our result. 
Result so far: 17560.9
If we take 7695 away from 8390, we end up with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Advancing to step 10:
855 can be fit into 6950 8 times, resulting in a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 17560.98
The remainder is 110 after subtracting 6840 from 6950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 11:
1100 divided by 855 is 1 with a remainder of 245.
Use 1 as the next digit of our solution. 
Result so far: 17560.981
If we subtract 855 from 1100, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 12:
855 can be fit into 2450 2 times, resulting in a remainder of 740.
Write down 2 as next digit of the result. 
Result so far: 17560.9812
Subtract 1710 from 2450 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 13:
When dividing 7400 by 855, we get 8 with a remainder of 560.
Use 8 as the next digit of our solution. 
Result so far: 17560.98128
The remainder is 560 after subtracting 6840 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 14:
5600 divided by 855 is 6 with a remainder of 470.
The number 6 becomes the next digit in our result. 
Result so far: 17560.981286
Subtract 5130 from 5600 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 15:
The number 855 fits into 4700 5 times, leaving a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 17560.9812865
The remainder is 425 after subtracting 4275 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 16:
The number 855 fits into 4250 4 times, leaving a remainder of 830.
The number 4 becomes the next digit in our result. 
Result so far: 17560.98128654
If we take 3420 away from 4250, we end up with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

After the division, we end up with 17560.98128654 and a remainder of 8.3e-07.
