We're dividing 3991107 by 630 
Our goal is to divide 3991107 by 630.

Going ahead to step 1:
If we divide 3 by 630, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 630

Advancing to step 2:
39 divided by 630 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 630

Step 3:
399 divided by 630 is 0 with a remainder of 399.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Grab the next digit (1) from the dividend, add it to 399, then carry on: 3991 / 630

Advancing to step 4:
630 can be fit into 3991 6 times, resulting in a remainder of 211.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 211 after subtracting 3780 from 3991.
Include the next digit (1) from the dividend after 211, then repeat: 2111 / 630

Advancing to step 5:
If we divide 2111 by 630, we get 3 and a remainder of 221.
Use 3 as the next digit of our solution. 
Result so far: 63.0
The remainder is 221 after subtracting 1890 from 2111.
Grab the next digit (0) from the dividend, add it to 221, then carry on: 2210 / 630

On to step 6:
2210 divided by 630 is 3 with a remainder of 320.
Write down 3 as next digit of the result. 
Result so far: 633.0
Deduct 1890 from 2210 and we're left with 320.
Bring next digit (7) of the dividend behind the 320 and repeat the process: 3207 / 630

Going ahead to step 7:
630 goes into 3207 5 times with a remainder of 57.
Put 5 as the next digit of the answer. 
Result so far: 6335.0
If we subtract 3150 from 3207, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 8:
630 can be fit into 570 0 times, resulting in a remainder of 570.
Use 0 as the next digit of our solution. 
Result so far: 6335.0
Subtract 0 from 570 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 9:
If we divide 5700 by 630, we get 9 and a remainder of 30.
The next digit of our result is 9. 
Result so far: 6335.09
If we subtract 5670 from 5700, we 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.

Moving on to step 10:
If we divide 300 by 630, we get 0 and a remainder of 300.
The next digit of our result is 0. 
Result so far: 6335.09
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 11:
If we divide 3000 by 630, we get 4 and a remainder of 480.
Record the quotient 4 as the next digit in the result. 
Result so far: 6335.0904
Deduct 2520 from 3000 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 12:
630 goes into 4800 7 times with a remainder of 390.
Record the quotient 7 as the next digit in the result. 
Result so far: 6335.09047
Deduct 4410 from 4800 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 13:
If we divide 3900 by 630, we get 6 and a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 6335.090476
The remainder is 120 after subtracting 3780 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 14:
The number 630 fits into 1200 1 times, leaving a remainder of 570.
Use 1 as the next digit of our solution. 
Result so far: 6335.0904761
Deduct 630 from 1200 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 15:
5700 divided by 630 is 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 6335.09047619
The remainder is 30 after subtracting 5670 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 6335.09047619, and the remainder is 3e-08.
