We're dividing 53299249 by 630 
The aim is to understand the frequency of 630 in 53299249.

Going ahead to step 1:
If we divide 5 by 630, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 630

On to step 2:
The number 630 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 630

Advancing to step 3:
532 divided by 630 is 0 with a remainder of 532.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 532 leaves us with 532.
Include the next digit (9) from the dividend after 532, then repeat: 5329 / 630

Moving on to step 4:
The number 630 fits into 5329 8 times, leaving a remainder of 289.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 5040 from 5329, we get 289.
Grab the next digit (9) from the dividend, add it to 289, then carry on: 2899 / 630

Advancing to step 5:
When dividing 2899 by 630, we get 4 with a remainder of 379.
Write down 4 as next digit of the result. 
Result so far: 84.0
Deduct 2520 from 2899 and we're left with 379.
Fetch the next digit (2) from the dividend, attach it to 379 and continue: 3792 / 630

Advancing to step 6:
The number 630 fits into 3792 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 846.0
Subtract 3780 from 3792 to get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 630

Advancing to step 7:
630 can be fit into 124 0 times, resulting in a remainder of 124.
Use 0 as the next digit of our solution. 
Result so far: 8460.0
Deduct 0 from 124 and we're left with 124.
Include the next digit (9) from the dividend after 124, then repeat: 1249 / 630

Moving on to step 8:
The number 630 fits into 1249 1 times, leaving a remainder of 619.
Use 1 as the next digit of our solution. 
Result so far: 84601.0
Deduct 630 from 1249 and we're left with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Going ahead to step 9:
630 can be fit into 6190 9 times, resulting in a remainder of 520.
Use 9 as the next digit of our solution. 
Result so far: 84601.9
Subtract 5670 from 6190 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 10:
If we divide 5200 by 630, we get 8 and a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 84601.98
If we take 5040 away from 5200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 11:
630 goes into 1600 2 times with a remainder of 340.
The next digit of our result is 2. 
Result so far: 84601.982
The remainder is 340 after subtracting 1260 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 12:
630 can be fit into 3400 5 times, resulting in a remainder of 250.
The next digit of our result is 5. 
Result so far: 84601.9825
If we subtract 3150 from 3400, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 13:
630 can be fit into 2500 3 times, resulting in a remainder of 610.
Record the quotient 3 as the next digit in the result. 
Result so far: 84601.98253
If we subtract 1890 from 2500, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 14:
The number 630 fits into 6100 9 times, leaving a remainder of 430.
Record the quotient 9 as the next digit in the result. 
Result so far: 84601.982539
Deduct 5670 from 6100 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 15:
630 goes into 4300 6 times with a remainder of 520.
Record the quotient 6 as the next digit in the result. 
Result so far: 84601.9825396
If we subtract 3780 from 4300, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 16:
When dividing 5200 by 630, we get 8 with a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 84601.98253968
If we take 5040 away from 5200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 84601.98253968, with a leftover of 1.6e-07.
