Let's divide 30630630 by 210
Our goal is to divide 30630630 by 210.

Step 1:
210 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 210

Let's proceed to step 2:
30 divided by 210 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 210

Advancing to step 3:
When dividing 306 by 210, we get 1 with a remainder of 96.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 210 from 306 leaves us with 96.
Append the next digit (3) from the dividend to 96 and continue with: 963 / 210

Going ahead to step 4:
When dividing 963 by 210, we get 4 with a remainder of 123.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 840 from 963 to get 123.
Fetch the next digit (0) from the dividend, attach it to 123 and continue: 1230 / 210

Advancing to step 5:
1230 divided by 210 is 5 with a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 145.0
Subtracting 1050 from 1230 leaves us with 180.
Grab the next digit (6) from the dividend, add it to 180, then carry on: 1806 / 210

On to step 6:
210 can be fit into 1806 8 times, resulting in a remainder of 126.
Record the quotient 8 as the next digit in the result. 
Result so far: 1458.0
The remainder is 126 after subtracting 1680 from 1806.
Take the next digit (3) from the dividend and append it to 126, then repeat: 1263 / 210

Moving on to step 7:
If we divide 1263 by 210, we get 6 and a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 14586.0
If we subtract 1260 from 1263, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 210

Step 8:
210 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: 145860.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
210 goes into 300 1 times with a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 145860.1
If we subtract 210 from 300, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
If we divide 900 by 210, we get 4 and a remainder of 60.
The next digit of our result is 4. 
Result so far: 145860.14
If we subtract 840 from 900, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
600 divided by 210 is 2 with a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 145860.142
The remainder is 180 after subtracting 420 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 12:
1800 divided by 210 is 8 with a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 145860.1428
Deduct 1680 from 1800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 13:
When dividing 1200 by 210, we get 5 with a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 145860.14285
The remainder is 150 after subtracting 1050 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 14:
When dividing 1500 by 210, we get 7 with a remainder of 30.
The next digit of our result is 7. 
Result so far: 145860.142857
Subtract 1470 from 1500 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 15:
210 goes into 300 1 times with a remainder of 90.
The next digit of our result is 1. 
Result so far: 145860.1428571
If we take 210 away from 300, 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.

Let's proceed to step 16:
900 divided by 210 is 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 145860.14285714
If we subtract 840 from 900, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 145860.14285714 and a remainder of 6e-08.
