We're dividing 29136428 by 630 
The aim is to understand the frequency of 630 in 29136428.

Advancing to step 1:
2 divided by 630 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 630

Moving on to step 2:
29 divided by 630 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 630

Let's proceed to step 3:
630 goes into 291 0 times with a remainder of 291.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 291, we end up with 291.
Bring next digit (3) of the dividend behind the 291 and repeat the process: 2913 / 630

On to step 4:
If we divide 2913 by 630, we get 4 and a remainder of 393.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 2520 from 2913 and we're left with 393.
Append the next digit (6) from the dividend to 393 and continue with: 3936 / 630

Step 5:
630 goes into 3936 6 times with a remainder of 156.
The next digit of our result is 6. 
Result so far: 46.0
If we subtract 3780 from 3936, we get 156.
Append the next digit (4) from the dividend to 156 and continue with: 1564 / 630

Let's proceed to step 6:
1564 divided by 630 is 2 with a remainder of 304.
Put 2 as the next digit of the answer. 
Result so far: 462.0
Deduct 1260 from 1564 and we're left with 304.
Append the next digit (2) from the dividend to 304 and continue with: 3042 / 630

Going ahead to step 7:
630 can be fit into 3042 4 times, resulting in a remainder of 522.
Record the quotient 4 as the next digit in the result. 
Result so far: 4624.0
Deduct 2520 from 3042 and we're left with 522.
Append the next digit (8) from the dividend to 522 and continue with: 5228 / 630

Going ahead to step 8:
5228 divided by 630 is 8 with a remainder of 188.
The number 8 becomes the next digit in our result. 
Result so far: 46248.0
If we take 5040 away from 5228, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 9:
When dividing 1880 by 630, we get 2 with a remainder of 620.
Record the quotient 2 as the next digit in the result. 
Result so far: 46248.2
Subtracting 1260 from 1880 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 10:
630 goes into 6200 9 times with a remainder of 530.
The next digit of our result is 9. 
Result so far: 46248.29
Deduct 5670 from 6200 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 11:
The number 630 fits into 5300 8 times, leaving a remainder of 260.
The next digit of our result is 8. 
Result so far: 46248.298
If we take 5040 away from 5300, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 12:
630 goes into 2600 4 times with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 46248.2984
If we subtract 2520 from 2600, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
The number 630 fits into 800 1 times, leaving a remainder of 170.
Record the quotient 1 as the next digit in the result. 
Result so far: 46248.29841
Subtract 630 from 800 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 14:
1700 divided by 630 is 2 with a remainder of 440.
Write down 2 as next digit of the result. 
Result so far: 46248.298412
Subtract 1260 from 1700 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 15:
When dividing 4400 by 630, we get 6 with a remainder of 620.
The next digit of our result is 6. 
Result so far: 46248.2984126
Deduct 3780 from 4400 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 16:
630 can be fit into 6200 9 times, resulting in a remainder of 530.
Write down 9 as next digit of the result. 
Result so far: 46248.29841269
Subtracting 5670 from 6200 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

The final outcome is 46248.29841269, with a leftover of 5.3e-07.
