Let's divide 17217679 by 630
The aim is to understand the frequency of 630 in 17217679.

Advancing to step 1:
630 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 630

On to step 2:
If we divide 17 by 630, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 630

Step 3:
630 goes into 172 0 times with a remainder of 172.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 172 to get 172.
Grab the next digit (1) from the dividend, add it to 172, then carry on: 1721 / 630

Moving on to step 4:
The number 630 fits into 1721 2 times, leaving a remainder of 461.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1260 from 1721 leaves us with 461.
Include the next digit (7) from the dividend after 461, then repeat: 4617 / 630

Going ahead to step 5:
4617 divided by 630 is 7 with a remainder of 207.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 4410 from 4617 leaves us with 207.
Append the next digit (6) from the dividend to 207 and continue with: 2076 / 630

Step 6:
630 can be fit into 2076 3 times, resulting in a remainder of 186.
Put 3 as the next digit of the answer. 
Result so far: 273.0
Subtracting 1890 from 2076 leaves us with 186.
Append the next digit (7) from the dividend to 186 and continue with: 1867 / 630

On to step 7:
630 can be fit into 1867 2 times, resulting in a remainder of 607.
Use 2 as the next digit of our solution. 
Result so far: 2732.0
Deduct 1260 from 1867 and we're left with 607.
Include the next digit (9) from the dividend after 607, then repeat: 6079 / 630

Let's proceed to step 8:
630 can be fit into 6079 9 times, resulting in a remainder of 409.
Use 9 as the next digit of our solution. 
Result so far: 27329.0
Deduct 5670 from 6079 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Going ahead to step 9:
630 goes into 4090 6 times with a remainder of 310.
Put 6 as the next digit of the answer. 
Result so far: 27329.6
If we subtract 3780 from 4090, 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.

Step 10:
630 can be fit into 3100 4 times, resulting in a remainder of 580.
The number 4 becomes the next digit in our result. 
Result so far: 27329.64
The remainder is 580 after subtracting 2520 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 11:
630 can be fit into 5800 9 times, resulting in a remainder of 130.
Use 9 as the next digit of our solution. 
Result so far: 27329.649
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.

Moving on to step 12:
The number 630 fits into 1300 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 27329.6492
Deduct 1260 from 1300 and we're left 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.

Let's proceed to step 13:
400 divided by 630 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 27329.6492
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 14:
4000 divided by 630 is 6 with a remainder of 220.
Put 6 as the next digit of the answer. 
Result so far: 27329.649206
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.

Step 15:
When dividing 2200 by 630, we get 3 with a remainder of 310.
Write down 3 as next digit of the result. 
Result so far: 27329.6492063
Deduct 1890 from 2200 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 16:
When dividing 3100 by 630, we get 4 with a remainder of 580.
Write down 4 as next digit of the result. 
Result so far: 27329.64920634
If we take 2520 away from 3100, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

After the division, we end up with 27329.64920634 and a remainder of 5.8e-07.
