30172635 ÷ 664 
We want to figure out the number of times 30172635 can be divided by 664.

Going ahead to step 1:
3 divided by 664 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 664

Moving on to step 2:
The number 664 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 664

Going ahead to step 3:
664 can be fit into 301 0 times, resulting in a remainder of 301.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 301 after subtracting 0 from 301.
Fetch the next digit (7) from the dividend, attach it to 301 and continue: 3017 / 664

Going ahead to step 4:
664 can be fit into 3017 4 times, resulting in a remainder of 361.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 2656 from 3017 to get 361.
Bring next digit (2) of the dividend behind the 361 and repeat the process: 3612 / 664

Advancing to step 5:
When dividing 3612 by 664, we get 5 with a remainder of 292.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 3320 from 3612 leaves us with 292.
Take the next digit (6) from the dividend and append it to 292, then repeat: 2926 / 664

Moving on to step 6:
664 can be fit into 2926 4 times, resulting in a remainder of 270.
The number 4 becomes the next digit in our result. 
Result so far: 454.0
Deduct 2656 from 2926 and we're left with 270.
Append the next digit (3) from the dividend to 270 and continue with: 2703 / 664

Moving on to step 7:
When dividing 2703 by 664, we get 4 with a remainder of 47.
The number 4 becomes the next digit in our result. 
Result so far: 4544.0
If we take 2656 away from 2703, we end up with 47.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 664

Let's proceed to step 8:
475 divided by 664 is 0 with a remainder of 475.
Put 0 as the next digit of the answer. 
Result so far: 45440.0
If we subtract 0 from 475, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 9:
If we divide 4750 by 664, we get 7 and a remainder of 102.
Write down 7 as next digit of the result. 
Result so far: 45440.7
Subtract 4648 from 4750 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 10:
664 can be fit into 1020 1 times, resulting in a remainder of 356.
Record the quotient 1 as the next digit in the result. 
Result so far: 45440.71
Subtracting 664 from 1020 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 11:
If we divide 3560 by 664, we get 5 and a remainder of 240.
The next digit of our result is 5. 
Result so far: 45440.715
If we take 3320 away from 3560, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
664 can be fit into 2400 3 times, resulting in a remainder of 408.
Put 3 as the next digit of the answer. 
Result so far: 45440.7153
Subtract 1992 from 2400 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 13:
When dividing 4080 by 664, we get 6 with a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 45440.71536
If we subtract 3984 from 4080, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 14:
664 can be fit into 960 1 times, resulting in a remainder of 296.
Use 1 as the next digit of our solution. 
Result so far: 45440.715361
If we take 664 away from 960, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 15:
The number 664 fits into 2960 4 times, leaving a remainder of 304.
Write down 4 as next digit of the result. 
Result so far: 45440.7153614
If we take 2656 away from 2960, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 16:
664 goes into 3040 4 times with a remainder of 384.
Use 4 as the next digit of our solution. 
Result so far: 45440.71536144
Deduct 2656 from 3040 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The quotient of the division is 45440.71536144, and the remainder is 3.84e-07.
