We look at the division of 175864 by 630 
The aim is to understand the frequency of 630 in 175864.

On to step 1:
When dividing 1 by 630, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 630

On to step 2:
630 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 630

Going ahead to step 3:
The number 630 fits into 175 0 times, leaving a remainder of 175.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 175 leaves us with 175.
Fetch the next digit (8) from the dividend, attach it to 175 and continue: 1758 / 630

On to step 4:
630 can be fit into 1758 2 times, resulting in a remainder of 498.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1260 from 1758 to get 498.
Take the next digit (6) from the dividend and append it to 498, then repeat: 4986 / 630

Moving on to step 5:
The number 630 fits into 4986 7 times, leaving a remainder of 576.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we subtract 4410 from 4986, we get 576.
Take the next digit (4) from the dividend and append it to 576, then repeat: 5764 / 630

Going ahead to step 6:
630 goes into 5764 9 times with a remainder of 94.
Write down 9 as next digit of the result. 
Result so far: 279.0
Deduct 5670 from 5764 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 7:
When dividing 940 by 630, we get 1 with a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 279.1
The remainder is 310 after subtracting 630 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 8:
630 goes into 3100 4 times with a remainder of 580.
Put 4 as the next digit of the answer. 
Result so far: 279.14
If we subtract 2520 from 3100, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 9:
If we divide 5800 by 630, we get 9 and a remainder of 130.
The next digit of our result is 9. 
Result so far: 279.149
The remainder is 130 after subtracting 5670 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
The number 630 fits into 1300 2 times, leaving a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 279.1492
If we take 1260 away from 1300, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
400 divided by 630 is 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 279.1492
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 12:
The number 630 fits into 4000 6 times, leaving a remainder of 220.
The next digit of our result is 6. 
Result so far: 279.149206
Subtract 3780 from 4000 to get 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 13:
The number 630 fits into 2200 3 times, leaving a remainder of 310.
Write down 3 as next digit of the result. 
Result so far: 279.1492063
If we subtract 1890 from 2200, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 14:
630 can be fit into 3100 4 times, resulting in a remainder of 580.
Use 4 as the next digit of our solution. 
Result so far: 279.14920634
If we subtract 2520 from 3100, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Our division results in 279.14920634 with a remaining 5.8e-07.
