Let's divide 74490988 by 603
We're looking to find how many times 603 goes into 74490988.

Step 1:
When dividing 7 by 603, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 603

Step 2:
The number 603 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 603

Let's proceed to step 3:
603 goes into 744 1 times with a remainder of 141.
The next digit of our result is 1. 
Result so far: 1.0
If we take 603 away from 744, we end up with 141.
Take the next digit (9) from the dividend and append it to 141, then repeat: 1419 / 603

Step 4:
The number 603 fits into 1419 2 times, leaving a remainder of 213.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1206 away from 1419, we end up with 213.
Grab the next digit (0) from the dividend, add it to 213, then carry on: 2130 / 603

Step 5:
When dividing 2130 by 603, we get 3 with a remainder of 321.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
The remainder is 321 after subtracting 1809 from 2130.
Grab the next digit (9) from the dividend, add it to 321, then carry on: 3219 / 603

Going ahead to step 6:
When dividing 3219 by 603, we get 5 with a remainder of 204.
Use 5 as the next digit of our solution. 
Result so far: 1235.0
Subtract 3015 from 3219 to get 204.
Grab the next digit (8) from the dividend, add it to 204, then carry on: 2048 / 603

Moving on to step 7:
2048 divided by 603 is 3 with a remainder of 239.
The number 3 becomes the next digit in our result. 
Result so far: 12353.0
If we take 1809 away from 2048, we end up with 239.
Include the next digit (8) from the dividend after 239, then repeat: 2398 / 603

Let's proceed to step 8:
2398 divided by 603 is 3 with a remainder of 589.
Put 3 as the next digit of the answer. 
Result so far: 123533.0
If we take 1809 away from 2398, we end up with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Let's proceed to step 9:
603 can be fit into 5890 9 times, resulting in a remainder of 463.
Put 9 as the next digit of the answer. 
Result so far: 123533.9
Subtract 5427 from 5890 to get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Going ahead to step 10:
The number 603 fits into 4630 7 times, leaving a remainder of 409.
The number 7 becomes the next digit in our result. 
Result so far: 123533.97
If we take 4221 away from 4630, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Going ahead to step 11:
4090 divided by 603 is 6 with a remainder of 472.
Put 6 as the next digit of the answer. 
Result so far: 123533.976
If we subtract 3618 from 4090, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 12:
The number 603 fits into 4720 7 times, leaving a remainder of 499.
Write down 7 as next digit of the result. 
Result so far: 123533.9767
Subtract 4221 from 4720 to get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Advancing to step 13:
If we divide 4990 by 603, we get 8 and a remainder of 166.
Use 8 as the next digit of our solution. 
Result so far: 123533.97678
If we subtract 4824 from 4990, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 14:
The number 603 fits into 1660 2 times, leaving a remainder of 454.
The number 2 becomes the next digit in our result. 
Result so far: 123533.976782
Deduct 1206 from 1660 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 15:
603 can be fit into 4540 7 times, resulting in a remainder of 319.
Put 7 as the next digit of the answer. 
Result so far: 123533.9767827
Subtracting 4221 from 4540 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Let's proceed to step 16:
If we divide 3190 by 603, we get 5 and a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 123533.97678275
Deduct 3015 from 3190 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final outcome is 123533.97678275, with a leftover of 1.75e-07.
