We look at the division of 1462990 by 630 
The aim is to understand the frequency of 630 in 1462990.

Going ahead to step 1:
The number 630 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 630

On to step 2:
The number 630 fits into 14 0 times, leaving a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 630

Advancing to step 3:
630 can be fit into 146 0 times, resulting in a remainder of 146.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 146 to get 146.
Take the next digit (2) from the dividend and append it to 146, then repeat: 1462 / 630

Moving on to step 4:
If we divide 1462 by 630, we get 2 and a remainder of 202.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1260 from 1462 and we're left with 202.
Take the next digit (9) from the dividend and append it to 202, then repeat: 2029 / 630

Moving on to step 5:
If we divide 2029 by 630, we get 3 and a remainder of 139.
The next digit of our result is 3. 
Result so far: 23.0
If we take 1890 away from 2029, we end up with 139.
Include the next digit (9) from the dividend after 139, then repeat: 1399 / 630

On to step 6:
1399 divided by 630 is 2 with a remainder of 139.
The number 2 becomes the next digit in our result. 
Result so far: 232.0
Subtract 1260 from 1399 to get 139.
Fetch the next digit (0) from the dividend, attach it to 139 and continue: 1390 / 630

Moving on to step 7:
The number 630 fits into 1390 2 times, leaving a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 2322.0
The remainder is 130 after subtracting 1260 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 8:
630 can be fit into 1300 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 2322.2
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.

Going ahead to step 9:
When dividing 400 by 630, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 2322.2
If we take 0 away from 400, we end up with 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 10:
4000 divided by 630 is 6 with a remainder of 220.
Record the quotient 6 as the next digit in the result. 
Result so far: 2322.206
The remainder is 220 after subtracting 3780 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 11:
630 goes into 2200 3 times with a remainder of 310.
Record the quotient 3 as the next digit in the result. 
Result so far: 2322.2063
Subtract 1890 from 2200 to 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.

Moving on to step 12:
3100 divided by 630 is 4 with a remainder of 580.
The next digit of our result is 4. 
Result so far: 2322.20634
Subtract 2520 from 3100 to 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.

Let's proceed to step 13:
The number 630 fits into 5800 9 times, leaving a remainder of 130.
Put 9 as the next digit of the answer. 
Result so far: 2322.206349
Subtracting 5670 from 5800 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 14:
When dividing 1300 by 630, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2322.2063492
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 15:
630 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 2322.2063492
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 2322.2063492, with a leftover of 4e-07.
