Let's see how many times 623 fits into 18788757.

On to step 1:
1 divided by 623 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 623

Going ahead to step 2:
The number 623 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 623

Advancing to step 3:
623 can be fit into 187 0 times, resulting in a remainder of 187.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 187 and we're left with 187.
Take the next digit (8) from the dividend and append it to 187, then repeat: 1878 / 623

Let's proceed to step 4:
When dividing 1878 by 623, we get 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1869 from 1878 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 623

Moving on to step 5:
If we divide 98 by 623, we get 0 and a remainder of 98.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 98 after subtracting 0 from 98.
Append the next digit (7) from the dividend to 98 and continue with: 987 / 623

Advancing to step 6:
If we divide 987 by 623, we get 1 and a remainder of 364.
Put 1 as the next digit of the answer. 
Result so far: 301.0
Subtracting 623 from 987 leaves us with 364.
Bring next digit (5) of the dividend behind the 364 and repeat the process: 3645 / 623

Going ahead to step 7:
623 can be fit into 3645 5 times, resulting in a remainder of 530.
Record the quotient 5 as the next digit in the result. 
Result so far: 3015.0
If we subtract 3115 from 3645, we get 530.
Take the next digit (7) from the dividend and append it to 530, then repeat: 5307 / 623

On to step 8:
623 can be fit into 5307 8 times, resulting in a remainder of 323.
The number 8 becomes the next digit in our result. 
Result so far: 30158.0
If we subtract 4984 from 5307, we get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 9:
The number 623 fits into 3230 5 times, leaving a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 30158.5
Deduct 3115 from 3230 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 10:
The number 623 fits into 1150 1 times, leaving a remainder of 527.
Use 1 as the next digit of our solution. 
Result so far: 30158.51
Subtracting 623 from 1150 leaves us with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

On to step 11:
The number 623 fits into 5270 8 times, leaving a remainder of 286.
Write down 8 as next digit of the result. 
Result so far: 30158.518
Subtracting 4984 from 5270 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 12:
The number 623 fits into 2860 4 times, leaving a remainder of 368.
Record the quotient 4 as the next digit in the result. 
Result so far: 30158.5184
Subtract 2492 from 2860 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 13:
623 can be fit into 3680 5 times, resulting in a remainder of 565.
The number 5 becomes the next digit in our result. 
Result so far: 30158.51845
The remainder is 565 after subtracting 3115 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Going ahead to step 14:
If we divide 5650 by 623, we get 9 and a remainder of 43.
The next digit of our result is 9. 
Result so far: 30158.518459
Deduct 5607 from 5650 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 15:
If we divide 430 by 623, we get 0 and a remainder of 430.
The next digit of our result is 0. 
Result so far: 30158.518459
If we subtract 0 from 430, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 16:
623 can be fit into 4300 6 times, resulting in a remainder of 562.
Use 6 as the next digit of our solution. 
Result so far: 30158.51845906
The remainder is 562 after subtracting 3738 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

The final outcome is 30158.51845906, with a leftover of 5.62e-07.
