Let's divide 28971630 by 630
Our goal is to divide 28971630 by 630.

On to step 1:
If we divide 2 by 630, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 630

Let's proceed to step 2:
If we divide 28 by 630, we get 0 and a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 630

Advancing to step 3:
When dividing 289 by 630, we get 0 with a remainder of 289.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 289, we get 289.
Include the next digit (7) from the dividend after 289, then repeat: 2897 / 630

Let's proceed to step 4:
When dividing 2897 by 630, we get 4 with a remainder of 377.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 2520 from 2897, we get 377.
Grab the next digit (1) from the dividend, add it to 377, then carry on: 3771 / 630

Let's proceed to step 5:
The number 630 fits into 3771 5 times, leaving a remainder of 621.
Write down 5 as next digit of the result. 
Result so far: 45.0
The remainder is 621 after subtracting 3150 from 3771.
Fetch the next digit (6) from the dividend, attach it to 621 and continue: 6216 / 630

Step 6:
When dividing 6216 by 630, we get 9 with a remainder of 546.
Write down 9 as next digit of the result. 
Result so far: 459.0
Deduct 5670 from 6216 and we're left with 546.
Take the next digit (3) from the dividend and append it to 546, then repeat: 5463 / 630

Moving on to step 7:
5463 divided by 630 is 8 with a remainder of 423.
Put 8 as the next digit of the answer. 
Result so far: 4598.0
If we take 5040 away from 5463, we end up with 423.
Take the next digit (0) from the dividend and append it to 423, then repeat: 4230 / 630

Moving on to step 8:
630 goes into 4230 6 times with a remainder of 450.
The next digit of our result is 6. 
Result so far: 45986.0
Deduct 3780 from 4230 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 9:
The number 630 fits into 4500 7 times, leaving a remainder of 90.
Put 7 as the next digit of the answer. 
Result so far: 45986.7
The remainder is 90 after subtracting 4410 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
900 divided by 630 is 1 with a remainder of 270.
Put 1 as the next digit of the answer. 
Result so far: 45986.71
Subtracting 630 from 900 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 11:
If we divide 2700 by 630, we get 4 and a remainder of 180.
Use 4 as the next digit of our solution. 
Result so far: 45986.714
The remainder is 180 after subtracting 2520 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 12:
1800 divided by 630 is 2 with a remainder of 540.
Use 2 as the next digit of our solution. 
Result so far: 45986.7142
Subtract 1260 from 1800 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 13:
If we divide 5400 by 630, we get 8 and a remainder of 360.
Use 8 as the next digit of our solution. 
Result so far: 45986.71428
If we take 5040 away from 5400, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 14:
630 goes into 3600 5 times with a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 45986.714285
Subtracting 3150 from 3600 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 15:
When dividing 4500 by 630, we get 7 with a remainder of 90.
Record the quotient 7 as the next digit in the result. 
Result so far: 45986.7142857
If we take 4410 away from 4500, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 16:
630 can be fit into 900 1 times, resulting in a remainder of 270.
The number 1 becomes the next digit in our result. 
Result so far: 45986.71428571
The remainder is 270 after subtracting 630 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final outcome is 45986.71428571, with a leftover of 2.7e-07.
