Let's divide 74088303 by 561
We want to figure out the number of times 74088303 can be divided by 561.

Going ahead to step 1:
When dividing 7 by 561, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 561

Going ahead to step 2:
561 can be fit into 74 0 times, resulting in a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Take the next digit (0) from the dividend and append it to 74, then repeat: 740 / 561

Step 3:
The number 561 fits into 740 1 times, leaving a remainder of 179.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 561 from 740 and we're left with 179.
Bring next digit (8) of the dividend behind the 179 and repeat the process: 1798 / 561

Going ahead to step 4:
1798 divided by 561 is 3 with a remainder of 115.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1683 from 1798 leaves us with 115.
Include the next digit (8) from the dividend after 115, then repeat: 1158 / 561

Let's proceed to step 5:
The number 561 fits into 1158 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
If we take 1122 away from 1158, we end up with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 561

On to step 6:
561 can be fit into 363 0 times, resulting in a remainder of 363.
The number 0 becomes the next digit in our result. 
Result so far: 1320.0
The remainder is 363 after subtracting 0 from 363.
Include the next digit (0) from the dividend after 363, then repeat: 3630 / 561

Let's proceed to step 7:
561 can be fit into 3630 6 times, resulting in a remainder of 264.
Put 6 as the next digit of the answer. 
Result so far: 13206.0
If we subtract 3366 from 3630, we get 264.
Append the next digit (3) from the dividend to 264 and continue with: 2643 / 561

Advancing to step 8:
561 goes into 2643 4 times with a remainder of 399.
The number 4 becomes the next digit in our result. 
Result so far: 132064.0
If we subtract 2244 from 2643, we get 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Step 9:
If we divide 3990 by 561, we get 7 and a remainder of 63.
The next digit of our result is 7. 
Result so far: 132064.7
Subtract 3927 from 3990 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 10:
561 can be fit into 630 1 times, resulting in a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 132064.71
Subtract 561 from 630 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 11:
561 can be fit into 690 1 times, resulting in a remainder of 129.
Put 1 as the next digit of the answer. 
Result so far: 132064.711
If we subtract 561 from 690, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The quotient of the division is 132064.711, and the remainder is 0.0129.
