97591137 ÷ 12 
We want to divide 97591137 by 12.

Let's proceed to step 1:
When dividing 9 by 12, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 12

On to step 2:
12 can be fit into 97 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 1 after subtracting 96 from 97.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 12

On to step 3:
15 divided by 12 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 81.0
The remainder is 3 after subtracting 12 from 15.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 12

Step 4:
The number 12 fits into 39 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 813.0
The remainder is 3 after subtracting 36 from 39.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 12

Going ahead to step 5:
12 goes into 31 2 times with a remainder of 7.
The next digit of our result is 2. 
Result so far: 8132.0
The remainder is 7 after subtracting 24 from 31.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 12

Advancing to step 6:
When dividing 71 by 12, we get 5 with a remainder of 11.
The next digit of our result is 5. 
Result so far: 81325.0
The remainder is 11 after subtracting 60 from 71.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 12

Let's proceed to step 7:
12 can be fit into 113 9 times, resulting in a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 813259.0
Subtract 108 from 113 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 12

Advancing to step 8:
The number 12 fits into 57 4 times, leaving a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 8132594.0
The remainder is 9 after subtracting 48 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
90 divided by 12 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 8132594.7
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8132594.75
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 12, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8132594.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8132594.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 8132594.75 with a remainder of 0.0.
