74754429 divided by 623 
Let's see how many times 623 fits into 74754429.

Advancing to step 1:
623 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 623

Moving on to step 2:
623 can be fit into 74 0 times, resulting in a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Bring next digit (7) of the dividend behind the 74 and repeat the process: 747 / 623

Let's proceed to step 3:
623 can be fit into 747 1 times, resulting in a remainder of 124.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 124 after subtracting 623 from 747.
Append the next digit (5) from the dividend to 124 and continue with: 1245 / 623

Going ahead to step 4:
The number 623 fits into 1245 1 times, leaving a remainder of 622.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 623 away from 1245, we end up with 622.
Take the next digit (4) from the dividend and append it to 622, then repeat: 6224 / 623

Let's proceed to step 5:
The number 623 fits into 6224 9 times, leaving a remainder of 617.
Write down 9 as next digit of the result. 
Result so far: 119.0
The remainder is 617 after subtracting 5607 from 6224.
Fetch the next digit (4) from the dividend, attach it to 617 and continue: 6174 / 623

Moving on to step 6:
623 goes into 6174 9 times with a remainder of 567.
Put 9 as the next digit of the answer. 
Result so far: 1199.0
Subtracting 5607 from 6174 leaves us with 567.
Include the next digit (2) from the dividend after 567, then repeat: 5672 / 623

Step 7:
623 can be fit into 5672 9 times, resulting in a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 11999.0
If we subtract 5607 from 5672, we get 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 623

Step 8:
When dividing 659 by 623, we get 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 119991.0
Deduct 623 from 659 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
623 goes into 360 0 times with a remainder of 360.
The next digit of our result is 0. 
Result so far: 119991.0
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
If we divide 3600 by 623, we get 5 and a remainder of 485.
The next digit of our result is 5. 
Result so far: 119991.05
If we subtract 3115 from 3600, we get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Moving on to step 11:
If we divide 4850 by 623, we get 7 and a remainder of 489.
The next digit of our result is 7. 
Result so far: 119991.057
Subtracting 4361 from 4850 leaves us with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 12:
When dividing 4890 by 623, we get 7 with a remainder of 529.
The next digit of our result is 7. 
Result so far: 119991.0577
Deduct 4361 from 4890 and we're left with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

The final outcome is 119991.0577, with a leftover of 0.00529.
