Let's divide 72378642 by 665
We're looking to find how many times 665 goes into 72378642.

Moving on to step 1:
7 divided by 665 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 665

Step 2:
72 divided by 665 is 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 665

Moving on to step 3:
723 divided by 665 is 1 with a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 665 away from 723, we end up with 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 665

On to step 4:
665 can be fit into 587 0 times, resulting in a remainder of 587.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 587 leaves us with 587.
Include the next digit (8) from the dividend after 587, then repeat: 5878 / 665

Moving on to step 5:
5878 divided by 665 is 8 with a remainder of 558.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we take 5320 away from 5878, we end up with 558.
Fetch the next digit (6) from the dividend, attach it to 558 and continue: 5586 / 665

Step 6:
If we divide 5586 by 665, we get 8 and a remainder of 266.
The number 8 becomes the next digit in our result. 
Result so far: 1088.0
Subtracting 5320 from 5586 leaves us with 266.
Fetch the next digit (4) from the dividend, attach it to 266 and continue: 2664 / 665

Going ahead to step 7:
When dividing 2664 by 665, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 10884.0
If we subtract 2660 from 2664, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 665

Moving on to step 8:
If we divide 42 by 665, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 108840.0
Subtracting 0 from 42 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
If we divide 420 by 665, we get 0 and a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 108840.0
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 10:
When dividing 4200 by 665, we get 6 with a remainder of 210.
Write down 6 as next digit of the result. 
Result so far: 108840.06
The remainder is 210 after subtracting 3990 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 11:
665 goes into 2100 3 times with a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 108840.063
Subtracting 1995 from 2100 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 12:
665 can be fit into 1050 1 times, resulting in a remainder of 385.
Put 1 as the next digit of the answer. 
Result so far: 108840.0631
The remainder is 385 after subtracting 665 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 13:
665 goes into 3850 5 times with a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 108840.06315
Subtract 3325 from 3850 to get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Moving on to step 14:
5250 divided by 665 is 7 with a remainder of 595.
The number 7 becomes the next digit in our result. 
Result so far: 108840.063157
Deduct 4655 from 5250 and we're left with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Going ahead to step 15:
When dividing 5950 by 665, we get 8 with a remainder of 630.
Use 8 as the next digit of our solution. 
Result so far: 108840.0631578
Subtract 5320 from 5950 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 16:
665 goes into 6300 9 times with a remainder of 315.
The number 9 becomes the next digit in our result. 
Result so far: 108840.06315789
The remainder is 315 after subtracting 5985 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final result is 108840.06315789 with a remainder of 3.15e-07.
