12666371 ÷ 97 
Let's see how many times 97 fits into 12666371.

Moving on to step 1:
When dividing 1 by 97, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 97

Moving on to step 2:
The number 97 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 97

Step 3:
When dividing 126 by 97, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 97 from 126 and we're left with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 97

Step 4:
296 divided by 97 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 291 from 296 and we're left with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 97

Going ahead to step 5:
If we divide 56 by 97, we get 0 and a remainder of 56.
The next digit of our result is 0. 
Result so far: 130.0
Subtract 0 from 56 to get 56.
Grab the next digit (3) from the dividend, add it to 56, then carry on: 563 / 97

Step 6:
If we divide 563 by 97, we get 5 and a remainder of 78.
Put 5 as the next digit of the answer. 
Result so far: 1305.0
The remainder is 78 after subtracting 485 from 563.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 97

Advancing to step 7:
97 can be fit into 787 8 times, resulting in a remainder of 11.
The next digit of our result is 8. 
Result so far: 13058.0
The remainder is 11 after subtracting 776 from 787.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 97

Advancing to step 8:
97 can be fit into 111 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 130581.0
Deduct 97 from 111 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
97 can be fit into 140 1 times, resulting in a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 130581.1
If we subtract 97 from 140, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 10:
The number 97 fits into 430 4 times, leaving a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 130581.14
If we subtract 388 from 430, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
The number 97 fits into 420 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 130581.144
Subtracting 388 from 420 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 130581.144, with a leftover of 0.0032.
