84721350 ÷ 630 
We want to divide 84721350 by 630.

Moving on to step 1:
630 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 630

Going ahead to step 2:
84 divided by 630 is 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Take the next digit (7) from the dividend and append it to 84, then repeat: 847 / 630

Moving on to step 3:
630 can be fit into 847 1 times, resulting in a remainder of 217.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 630 from 847 to get 217.
Bring next digit (2) of the dividend behind the 217 and repeat the process: 2172 / 630

Let's proceed to step 4:
When dividing 2172 by 630, we get 3 with a remainder of 282.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1890 away from 2172, we end up with 282.
Append the next digit (1) from the dividend to 282 and continue with: 2821 / 630

Let's proceed to step 5:
630 can be fit into 2821 4 times, resulting in a remainder of 301.
Use 4 as the next digit of our solution. 
Result so far: 134.0
If we take 2520 away from 2821, we end up with 301.
Fetch the next digit (3) from the dividend, attach it to 301 and continue: 3013 / 630

Going ahead to step 6:
630 goes into 3013 4 times with a remainder of 493.
Put 4 as the next digit of the answer. 
Result so far: 1344.0
Deduct 2520 from 3013 and we're left with 493.
Bring next digit (5) of the dividend behind the 493 and repeat the process: 4935 / 630

Let's proceed to step 7:
4935 divided by 630 is 7 with a remainder of 525.
The next digit of our result is 7. 
Result so far: 13447.0
Subtracting 4410 from 4935 leaves us with 525.
Bring next digit (0) of the dividend behind the 525 and repeat the process: 5250 / 630

Moving on to step 8:
The number 630 fits into 5250 8 times, leaving a remainder of 210.
Put 8 as the next digit of the answer. 
Result so far: 134478.0
Subtracting 5040 from 5250 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 9:
2100 divided by 630 is 3 with a remainder of 210.
Put 3 as the next digit of the answer. 
Result so far: 134478.3
If we subtract 1890 from 2100, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 10:
When dividing 2100 by 630, we get 3 with a remainder of 210.
The next digit of our result is 3. 
Result so far: 134478.33
Subtract 1890 from 2100 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

After the division, we end up with 134478.33 and a remainder of 0.21.
