We're dividing 97123257 by 135 
We want to figure out the number of times 97123257 can be divided by 135.

On to step 1:
If we divide 9 by 135, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 135

Going ahead to step 2:
135 can be fit into 97 0 times, resulting in a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Append the next digit (1) from the dividend to 97 and continue with: 971 / 135

Step 3:
971 divided by 135 is 7 with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 945 from 971 and we're left with 26.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 135

Step 4:
The number 135 fits into 262 1 times, leaving a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we subtract 135 from 262, we get 127.
Append the next digit (3) from the dividend to 127 and continue with: 1273 / 135

Let's proceed to step 5:
1273 divided by 135 is 9 with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 719.0
If we take 1215 away from 1273, we end up with 58.
Grab the next digit (2) from the dividend, add it to 58, then carry on: 582 / 135

Moving on to step 6:
582 divided by 135 is 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 7194.0
Subtracting 540 from 582 leaves us with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 135

Advancing to step 7:
The number 135 fits into 425 3 times, leaving a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 71943.0
If we take 405 away from 425, we end up with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 135

Step 8:
207 divided by 135 is 1 with a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 719431.0
If we take 135 away from 207, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
The number 135 fits into 720 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 719431.5
Deduct 675 from 720 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
The number 135 fits into 450 3 times, leaving a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 719431.53
If we subtract 405 from 450, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
The number 135 fits into 450 3 times, leaving a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 719431.533
Subtract 405 from 450 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 719431.533 with a remainder of 0.0045.
