399 divided by 630 is 0 with a remainder of 399.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 399 to get 399.
Take the next digit (7) from the dividend and append it to 399, then repeat: 3997 / 630

On to step 5:
630 can be fit into 3997 6 times, resulting in a remainder of 217.
The next digit of our result is 6. 
Result so far: 106.0
Subtract 3780 from 3997 to get 217.
Bring next digit (8) of the dividend behind the 217 and repeat the process: 2178 / 630

Step 6:
The number 630 fits into 2178 3 times, leaving a remainder of 288.
Record the quotient 3 as the next digit in the result. 
Result so far: 1063.0
Deduct 1890 from 2178 and we're left with 288.
Grab the next digit (2) from the dividend, add it to 288, then carry on: 2882 / 630

Advancing to step 7:
630 goes into 2882 4 times with a remainder of 362.
Use 4 as the next digit of our solution. 
Result so far: 10634.0
The remainder is 362 after subtracting 2520 from 2882.
Bring next digit (8) of the dividend behind the 362 and repeat the process: 3628 / 630

Moving on to step 8:
The number 630 fits into 3628 5 times, leaving a remainder of 478.
Use 5 as the next digit of our solution. 
Result so far: 106345.0
Deduct 3150 from 3628 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Moving on to step 9:
4780 divided by 630 is 7 with a remainder of 370.
The number 7 becomes the next digit in our result. 
Result so far: 106345.7
If we subtract 4410 from 4780, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 10:
3700 divided by 630 is 5 with a remainder of 550.
Use 5 as the next digit of our solution. 
Result so far: 106345.75
Subtracting 3150 from 3700 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 11:
630 goes into 5500 8 times with a remainder of 460.
Record the quotient 8 as the next digit in the result. 
Result so far: 106345.758
The remainder is 460 after subtracting 5040 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 12:
The number 630 fits into 4600 7 times, leaving a remainder of 190.
Write down 7 as next digit of the result. 
Result so far: 106345.7587
Deduct 4410 from 4600 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 13:
The number 630 fits into 1900 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 106345.75873
If we subtract 1890 from 1900, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
When dividing 100 by 630, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 106345.75873
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 15:
The number 630 fits into 1000 1 times, leaving a remainder of 370.
The next digit of our result is 1. 
Result so far: 106345.7587301
Deduct 630 from 1000 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 16:
630 goes into 3700 5 times with a remainder of 550.
The number 5 becomes the next digit in our result. 
Result so far: 106345.75873015
The remainder is 550 after subtracting 3150 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

In conclusion, the division gives 106345.75873015 with a balance of 5.5e-07.
