53408563 ÷ 74 
Our goal is to divide 53408563 by 74.

Advancing to step 1:
74 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 74

Let's proceed to step 2:
The number 74 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 74

Step 3:
If we divide 534 by 74, we get 7 and a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 16 after subtracting 518 from 534.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 74

Let's proceed to step 4:
74 goes into 160 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtracting 148 from 160 leaves us with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 74

Advancing to step 5:
74 goes into 128 1 times with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 721.0
If we take 74 away from 128, we end up with 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 74

Moving on to step 6:
The number 74 fits into 545 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 7217.0
If we subtract 518 from 545, we get 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 74

Moving on to step 7:
74 can be fit into 276 3 times, resulting in a remainder of 54.
The next digit of our result is 3. 
Result so far: 72173.0
If we subtract 222 from 276, we get 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 74

Going ahead to step 8:
543 divided by 74 is 7 with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 721737.0
Subtract 518 from 543 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
74 can be fit into 250 3 times, resulting in a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 721737.3
If we subtract 222 from 250, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
74 goes into 280 3 times with a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 721737.33
If we subtract 222 from 280, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 721737.33, with a leftover of 0.058.
