Let's divide 75342973 by 485
Our goal is to divide 75342973 by 485.

Advancing to step 1:
485 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 485

Step 2:
The number 485 fits into 75 0 times, leaving a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 485

Moving on to step 3:
When dividing 753 by 485, we get 1 with a remainder of 268.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 268 after subtracting 485 from 753.
Bring next digit (4) of the dividend behind the 268 and repeat the process: 2684 / 485

Advancing to step 4:
If we divide 2684 by 485, we get 5 and a remainder of 259.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 2425 away from 2684, we end up with 259.
Take the next digit (2) from the dividend and append it to 259, then repeat: 2592 / 485

Advancing to step 5:
485 goes into 2592 5 times with a remainder of 167.
Put 5 as the next digit of the answer. 
Result so far: 155.0
Deduct 2425 from 2592 and we're left with 167.
Take the next digit (9) from the dividend and append it to 167, then repeat: 1679 / 485

On to step 6:
The number 485 fits into 1679 3 times, leaving a remainder of 224.
Use 3 as the next digit of our solution. 
Result so far: 1553.0
Subtract 1455 from 1679 to get 224.
Append the next digit (7) from the dividend to 224 and continue with: 2247 / 485

Moving on to step 7:
The number 485 fits into 2247 4 times, leaving a remainder of 307.
Write down 4 as next digit of the result. 
Result so far: 15534.0
Subtracting 1940 from 2247 leaves us with 307.
Append the next digit (3) from the dividend to 307 and continue with: 3073 / 485

Let's proceed to step 8:
485 goes into 3073 6 times with a remainder of 163.
Write down 6 as next digit of the result. 
Result so far: 155346.0
The remainder is 163 after subtracting 2910 from 3073.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 9:
If we divide 1630 by 485, we get 3 and a remainder of 175.
The number 3 becomes the next digit in our result. 
Result so far: 155346.3
If we subtract 1455 from 1630, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 10:
485 can be fit into 1750 3 times, resulting in a remainder of 295.
The number 3 becomes the next digit in our result. 
Result so far: 155346.33
If we take 1455 away from 1750, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

The final outcome is 155346.33, with a leftover of 0.295.
