We're dividing 39735974 by 663 
We want to figure out the number of times 39735974 can be divided by 663.

Let's proceed to step 1:
663 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 663

Advancing to step 2:
The number 663 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 663

Advancing to step 3:
663 can be fit into 397 0 times, resulting in a remainder of 397.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 397 and we're left with 397.
Bring next digit (3) of the dividend behind the 397 and repeat the process: 3973 / 663

Let's proceed to step 4:
If we divide 3973 by 663, we get 5 and a remainder of 658.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 3315 from 3973 leaves us with 658.
Include the next digit (5) from the dividend after 658, then repeat: 6585 / 663

Going ahead to step 5:
When dividing 6585 by 663, we get 9 with a remainder of 618.
The next digit of our result is 9. 
Result so far: 59.0
If we subtract 5967 from 6585, we get 618.
Bring next digit (9) of the dividend behind the 618 and repeat the process: 6189 / 663

Step 6:
663 goes into 6189 9 times with a remainder of 222.
The number 9 becomes the next digit in our result. 
Result so far: 599.0
If we subtract 5967 from 6189, we get 222.
Take the next digit (7) from the dividend and append it to 222, then repeat: 2227 / 663

Going ahead to step 7:
The number 663 fits into 2227 3 times, leaving a remainder of 238.
Put 3 as the next digit of the answer. 
Result so far: 5993.0
Subtract 1989 from 2227 to get 238.
Include the next digit (4) from the dividend after 238, then repeat: 2384 / 663

Going ahead to step 8:
663 goes into 2384 3 times with a remainder of 395.
Write down 3 as next digit of the result. 
Result so far: 59933.0
If we take 1989 away from 2384, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

On to step 9:
663 goes into 3950 5 times with a remainder of 635.
Use 5 as the next digit of our solution. 
Result so far: 59933.5
Deduct 3315 from 3950 and we're left with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

On to step 10:
The number 663 fits into 6350 9 times, leaving a remainder of 383.
Write down 9 as next digit of the result. 
Result so far: 59933.59
The remainder is 383 after subtracting 5967 from 6350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Step 11:
If we divide 3830 by 663, we get 5 and a remainder of 515.
Put 5 as the next digit of the answer. 
Result so far: 59933.595
Subtract 3315 from 3830 to get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Going ahead to step 12:
5150 divided by 663 is 7 with a remainder of 509.
Use 7 as the next digit of our solution. 
Result so far: 59933.5957
If we take 4641 away from 5150, we end up with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Advancing to step 13:
5090 divided by 663 is 7 with a remainder of 449.
Record the quotient 7 as the next digit in the result. 
Result so far: 59933.59577
The remainder is 449 after subtracting 4641 from 5090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

The quotient of the division is 59933.59577, and the remainder is 0.000449.
