We look at the division of 97243315 by 642 
We're looking to find how many times 642 goes into 97243315.

Advancing to step 1:
642 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 642

On to step 2:
97 divided by 642 is 0 with a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Bring next digit (2) of the dividend behind the 97 and repeat the process: 972 / 642

Let's proceed to step 3:
972 divided by 642 is 1 with a remainder of 330.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 642 from 972 to get 330.
Include the next digit (4) from the dividend after 330, then repeat: 3304 / 642

Going ahead to step 4:
3304 divided by 642 is 5 with a remainder of 94.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 3210 from 3304, we get 94.
Grab the next digit (3) from the dividend, add it to 94, then carry on: 943 / 642

Let's proceed to step 5:
The number 642 fits into 943 1 times, leaving a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 151.0
The remainder is 301 after subtracting 642 from 943.
Fetch the next digit (3) from the dividend, attach it to 301 and continue: 3013 / 642

Moving on to step 6:
If we divide 3013 by 642, we get 4 and a remainder of 445.
The number 4 becomes the next digit in our result. 
Result so far: 1514.0
Subtracting 2568 from 3013 leaves us with 445.
Take the next digit (1) from the dividend and append it to 445, then repeat: 4451 / 642

On to step 7:
642 goes into 4451 6 times with a remainder of 599.
The number 6 becomes the next digit in our result. 
Result so far: 15146.0
If we take 3852 away from 4451, we end up with 599.
Fetch the next digit (5) from the dividend, attach it to 599 and continue: 5995 / 642

Going ahead to step 8:
642 can be fit into 5995 9 times, resulting in a remainder of 217.
The number 9 becomes the next digit in our result. 
Result so far: 151469.0
The remainder is 217 after subtracting 5778 from 5995.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 9:
2170 divided by 642 is 3 with a remainder of 244.
Write down 3 as next digit of the result. 
Result so far: 151469.3
The remainder is 244 after subtracting 1926 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 10:
642 goes into 2440 3 times with a remainder of 514.
The number 3 becomes the next digit in our result. 
Result so far: 151469.33
Subtracting 1926 from 2440 leaves us with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

The quotient of the division is 151469.33, and the remainder is 0.514.
