We're dividing 13893866 by 630 
The aim is to understand the frequency of 630 in 13893866.

Going ahead to step 1:
If we divide 1 by 630, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 630

On to step 2:
When dividing 13 by 630, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 630

Advancing to step 3:
630 can be fit into 138 0 times, resulting in a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 138, we get 138.
Fetch the next digit (9) from the dividend, attach it to 138 and continue: 1389 / 630

Step 4:
If we divide 1389 by 630, we get 2 and a remainder of 129.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1260 from 1389 to get 129.
Bring next digit (3) of the dividend behind the 129 and repeat the process: 1293 / 630

Step 5:
The number 630 fits into 1293 2 times, leaving a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 1260 from 1293 to get 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 630

Moving on to step 6:
If we divide 338 by 630, we get 0 and a remainder of 338.
Use 0 as the next digit of our solution. 
Result so far: 220.0
Subtract 0 from 338 to get 338.
Include the next digit (6) from the dividend after 338, then repeat: 3386 / 630

Going ahead to step 7:
The number 630 fits into 3386 5 times, leaving a remainder of 236.
The next digit of our result is 5. 
Result so far: 2205.0
Subtract 3150 from 3386 to get 236.
Append the next digit (6) from the dividend to 236 and continue with: 2366 / 630

Let's proceed to step 8:
If we divide 2366 by 630, we get 3 and a remainder of 476.
Use 3 as the next digit of our solution. 
Result so far: 22053.0
If we subtract 1890 from 2366, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 9:
4760 divided by 630 is 7 with a remainder of 350.
Record the quotient 7 as the next digit in the result. 
Result so far: 22053.7
The remainder is 350 after subtracting 4410 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
The number 630 fits into 3500 5 times, leaving a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 22053.75
Deduct 3150 from 3500 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 11:
3500 divided by 630 is 5 with a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 22053.755
If we subtract 3150 from 3500, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Our division results in 22053.755 with a remaining 0.035.
