49399513 ÷ 630 
The aim is to understand the frequency of 630 in 49399513.

Advancing to step 1:
The number 630 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 630

On to step 2:
The number 630 fits into 49 0 times, leaving a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 630

Let's proceed to step 3:
630 goes into 493 0 times with a remainder of 493.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 493 leaves us with 493.
Bring next digit (9) of the dividend behind the 493 and repeat the process: 4939 / 630

Going ahead to step 4:
630 goes into 4939 7 times with a remainder of 529.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 4410 from 4939 to get 529.
Bring next digit (9) of the dividend behind the 529 and repeat the process: 5299 / 630

Going ahead to step 5:
The number 630 fits into 5299 8 times, leaving a remainder of 259.
The next digit of our result is 8. 
Result so far: 78.0
Subtracting 5040 from 5299 leaves us with 259.
Fetch the next digit (5) from the dividend, attach it to 259 and continue: 2595 / 630

Step 6:
2595 divided by 630 is 4 with a remainder of 75.
Write down 4 as next digit of the result. 
Result so far: 784.0
Subtract 2520 from 2595 to get 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 630

On to step 7:
If we divide 751 by 630, we get 1 and a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 7841.0
Subtract 630 from 751 to get 121.
Append the next digit (3) from the dividend to 121 and continue with: 1213 / 630

Step 8:
630 can be fit into 1213 1 times, resulting in a remainder of 583.
The number 1 becomes the next digit in our result. 
Result so far: 78411.0
Subtract 630 from 1213 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

On to step 9:
The number 630 fits into 5830 9 times, leaving a remainder of 160.
Write down 9 as next digit of the result. 
Result so far: 78411.9
Subtracting 5670 from 5830 leaves us 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.

Going ahead to step 10:
630 can be fit into 1600 2 times, resulting in a remainder of 340.
Use 2 as the next digit of our solution. 
Result so far: 78411.92
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.

Advancing to step 11:
When dividing 3400 by 630, we get 5 with a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 78411.925
If we take 3150 away from 3400, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
630 goes into 2500 3 times with a remainder of 610.
Write down 3 as next digit of the result. 
Result so far: 78411.9253
The remainder is 610 after subtracting 1890 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 13:
6100 divided by 630 is 9 with a remainder of 430.
The number 9 becomes the next digit in our result. 
Result so far: 78411.92539
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 14:
630 can be fit into 4300 6 times, resulting in a remainder of 520.
Record the quotient 6 as the next digit in the result. 
Result so far: 78411.925396
If we take 3780 away from 4300, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 15:
630 can be fit into 5200 8 times, resulting in a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 78411.9253968
If we subtract 5040 from 5200, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 16:
630 can be fit into 1600 2 times, resulting in a remainder of 340.
Record the quotient 2 as the next digit in the result. 
Result so far: 78411.92539682
If we subtract 1260 from 1600, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final result is 78411.92539682 with a remainder of 3.4e-07.
