30542102 ÷ 630 
We want to figure out the number of times 30542102 can be divided by 630.

Advancing to step 1:
630 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 630

Moving on to step 2:
630 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 630

Let's proceed to step 3:
630 can be fit into 305 0 times, resulting in a remainder of 305.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 305 and we're left with 305.
Grab the next digit (4) from the dividend, add it to 305, then carry on: 3054 / 630

Advancing to step 4:
630 goes into 3054 4 times with a remainder of 534.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2520 away from 3054, we end up with 534.
Bring next digit (2) of the dividend behind the 534 and repeat the process: 5342 / 630

Going ahead to step 5:
630 goes into 5342 8 times with a remainder of 302.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 5040 from 5342 to get 302.
Bring next digit (1) of the dividend behind the 302 and repeat the process: 3021 / 630

Step 6:
The number 630 fits into 3021 4 times, leaving a remainder of 501.
Record the quotient 4 as the next digit in the result. 
Result so far: 484.0
The remainder is 501 after subtracting 2520 from 3021.
Bring next digit (0) of the dividend behind the 501 and repeat the process: 5010 / 630

On to step 7:
630 goes into 5010 7 times with a remainder of 600.
Record the quotient 7 as the next digit in the result. 
Result so far: 4847.0
Subtract 4410 from 5010 to get 600.
Bring next digit (2) of the dividend behind the 600 and repeat the process: 6002 / 630

On to step 8:
6002 divided by 630 is 9 with a remainder of 332.
The next digit of our result is 9. 
Result so far: 48479.0
Subtracting 5670 from 6002 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 9:
630 can be fit into 3320 5 times, resulting in a remainder of 170.
The next digit of our result is 5. 
Result so far: 48479.5
Subtracting 3150 from 3320 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
630 goes into 1700 2 times with a remainder of 440.
Use 2 as the next digit of our solution. 
Result so far: 48479.52
If we subtract 1260 from 1700, we 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.

Going ahead to step 11:
If we divide 4400 by 630, we get 6 and a remainder of 620.
Put 6 as the next digit of the answer. 
Result so far: 48479.526
The remainder is 620 after subtracting 3780 from 4400.
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 12:
6200 divided by 630 is 9 with a remainder of 530.
Record the quotient 9 as the next digit in the result. 
Result so far: 48479.5269
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.

Step 13:
If we divide 5300 by 630, we get 8 and a remainder of 260.
Write down 8 as next digit of the result. 
Result so far: 48479.52698
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 14:
The number 630 fits into 2600 4 times, leaving a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 48479.526984
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 15:
When dividing 800 by 630, we get 1 with a remainder of 170.
Write down 1 as next digit of the result. 
Result so far: 48479.5269841
If we subtract 630 from 800, we 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.

Advancing to step 16:
The number 630 fits into 1700 2 times, leaving a remainder of 440.
Write down 2 as next digit of the result. 
Result so far: 48479.52698412
If we take 1260 away from 1700, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The quotient of the division is 48479.52698412, and the remainder is 4.4e-07.
