We're dividing 630945 by 16 
Our goal is to divide 630945 by 16.

Advancing to step 1:
16 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 16

Moving on to step 2:
63 divided by 16 is 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 48 from 63 and we're left with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 16

Advancing to step 3:
When dividing 150 by 16, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtracting 144 from 150 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 16

Step 4:
16 goes into 69 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 394.0
If we take 64 away from 69, we end up with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 16

On to step 5:
The number 16 fits into 54 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3943.0
If we subtract 48 from 54, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 16

Moving on to step 6:
The number 16 fits into 65 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 39434.0
Subtract 64 from 65 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 16 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 39434.0
If we take 0 away from 10, we end up with 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 8:
The number 16 fits into 100 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 39434.06
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 16 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 39434.062
Deduct 32 from 40 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 16, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 39434.0625
If we subtract 80 from 80, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39434.0625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39434.0625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 39434.0625 and a remainder of 0.0.
