We look at the division of 31074692 by 630 
The aim is to understand the frequency of 630 in 31074692.

Going ahead to step 1:
If we divide 3 by 630, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 630

Let's proceed to step 2:
630 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 630

Advancing to step 3:
630 goes into 310 0 times with a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 310, we end up with 310.
Take the next digit (7) from the dividend and append it to 310, then repeat: 3107 / 630

Let's proceed to step 4:
If we divide 3107 by 630, we get 4 and a remainder of 587.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 2520 from 3107 and we're left with 587.
Bring next digit (4) of the dividend behind the 587 and repeat the process: 5874 / 630

Going ahead to step 5:
5874 divided by 630 is 9 with a remainder of 204.
The next digit of our result is 9. 
Result so far: 49.0
The remainder is 204 after subtracting 5670 from 5874.
Fetch the next digit (6) from the dividend, attach it to 204 and continue: 2046 / 630

Step 6:
630 can be fit into 2046 3 times, resulting in a remainder of 156.
Write down 3 as next digit of the result. 
Result so far: 493.0
Subtract 1890 from 2046 to get 156.
Bring next digit (9) of the dividend behind the 156 and repeat the process: 1569 / 630

Going ahead to step 7:
630 can be fit into 1569 2 times, resulting in a remainder of 309.
Put 2 as the next digit of the answer. 
Result so far: 4932.0
If we subtract 1260 from 1569, we get 309.
Grab the next digit (2) from the dividend, add it to 309, then carry on: 3092 / 630

Step 8:
If we divide 3092 by 630, we get 4 and a remainder of 572.
Write down 4 as next digit of the result. 
Result so far: 49324.0
If we subtract 2520 from 3092, we get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

On to step 9:
When dividing 5720 by 630, we get 9 with a remainder of 50.
The next digit of our result is 9. 
Result so far: 49324.9
Subtracting 5670 from 5720 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
If we divide 500 by 630, we get 0 and a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 49324.9
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 11:
630 can be fit into 5000 7 times, resulting in a remainder of 590.
Use 7 as the next digit of our solution. 
Result so far: 49324.907
If we take 4410 away from 5000, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 12:
The number 630 fits into 5900 9 times, leaving a remainder of 230.
Record the quotient 9 as the next digit in the result. 
Result so far: 49324.9079
The remainder is 230 after subtracting 5670 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 13:
2300 divided by 630 is 3 with a remainder of 410.
Use 3 as the next digit of our solution. 
Result so far: 49324.90793
If we take 1890 away from 2300, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 14:
The number 630 fits into 4100 6 times, leaving a remainder of 320.
Put 6 as the next digit of the answer. 
Result so far: 49324.907936
If we subtract 3780 from 4100, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 15:
630 can be fit into 3200 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 49324.9079365
If we subtract 3150 from 3200, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 16:
630 can be fit into 500 0 times, resulting in a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 49324.9079365
Subtracting 0 from 500 leaves us 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.

Our division results in 49324.9079365 with a remaining 5e-07.
