We look at the division of 17387628 by 623 
Let's see how many times 623 fits into 17387628.

Advancing to step 1:
If we divide 1 by 623, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 623

On to step 2:
The number 623 fits into 17 0 times, leaving a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 623

On to step 3:
If we divide 173 by 623, we get 0 and a remainder of 173.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 173 after subtracting 0 from 173.
Bring next digit (8) of the dividend behind the 173 and repeat the process: 1738 / 623

On to step 4:
1738 divided by 623 is 2 with a remainder of 492.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1246 from 1738, we get 492.
Grab the next digit (7) from the dividend, add it to 492, then carry on: 4927 / 623

Let's proceed to step 5:
4927 divided by 623 is 7 with a remainder of 566.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 4361 from 4927 and we're left with 566.
Fetch the next digit (6) from the dividend, attach it to 566 and continue: 5666 / 623

On to step 6:
The number 623 fits into 5666 9 times, leaving a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 279.0
The remainder is 59 after subtracting 5607 from 5666.
Grab the next digit (2) from the dividend, add it to 59, then carry on: 592 / 623

Moving on to step 7:
592 divided by 623 is 0 with a remainder of 592.
Use 0 as the next digit of our solution. 
Result so far: 2790.0
Deduct 0 from 592 and we're left with 592.
Bring next digit (8) of the dividend behind the 592 and repeat the process: 5928 / 623

Step 8:
623 goes into 5928 9 times with a remainder of 321.
The number 9 becomes the next digit in our result. 
Result so far: 27909.0
Subtract 5607 from 5928 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Advancing to step 9:
623 can be fit into 3210 5 times, resulting in a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 27909.5
The remainder is 95 after subtracting 3115 from 3210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 10:
623 can be fit into 950 1 times, resulting in a remainder of 327.
The next digit of our result is 1. 
Result so far: 27909.51
If we subtract 623 from 950, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Advancing to step 11:
623 can be fit into 3270 5 times, resulting in a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 27909.515
Subtracting 3115 from 3270 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 12:
1550 divided by 623 is 2 with a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 27909.5152
The remainder is 304 after subtracting 1246 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 13:
The number 623 fits into 3040 4 times, leaving a remainder of 548.
Use 4 as the next digit of our solution. 
Result so far: 27909.51524
Subtracting 2492 from 3040 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Step 14:
623 goes into 5480 8 times with a remainder of 496.
Put 8 as the next digit of the answer. 
Result so far: 27909.515248
Subtract 4984 from 5480 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 15:
If we divide 4960 by 623, we get 7 and a remainder of 599.
Write down 7 as next digit of the result. 
Result so far: 27909.5152487
If we subtract 4361 from 4960, we get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Moving on to step 16:
When dividing 5990 by 623, we get 9 with a remainder of 383.
The number 9 becomes the next digit in our result. 
Result so far: 27909.51524879
Subtract 5607 from 5990 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

After the division, we end up with 27909.51524879 and a remainder of 3.83e-07.
