12986391 ÷ 97 
We're looking to find how many times 97 goes into 12986391.

Going ahead to step 1:
97 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 97

Going ahead to step 2:
When dividing 12 by 97, we get 0 with 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.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 97

Let's proceed to step 3:
If we divide 129 by 97, we get 1 and a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 97 from 129 leaves us with 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 97

Advancing to step 4:
The number 97 fits into 328 3 times, leaving a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 291 from 328 leaves us with 37.
Take the next digit (6) from the dividend and append it to 37, then repeat: 376 / 97

Advancing to step 5:
If we divide 376 by 97, we get 3 and a remainder of 85.
Put 3 as the next digit of the answer. 
Result so far: 133.0
The remainder is 85 after subtracting 291 from 376.
Grab the next digit (3) from the dividend, add it to 85, then carry on: 853 / 97

Going ahead to step 6:
The number 97 fits into 853 8 times, leaving a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 1338.0
If we take 776 away from 853, we end up with 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 97

Advancing to step 7:
If we divide 779 by 97, we get 8 and a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 13388.0
Subtract 776 from 779 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 97

Going ahead to step 8:
When dividing 31 by 97, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 133880.0
Deduct 0 from 31 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
If we divide 310 by 97, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 133880.3
Deduct 291 from 310 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
97 can be fit into 190 1 times, resulting in a remainder of 93.
Use 1 as the next digit of our solution. 
Result so far: 133880.31
If we take 97 away from 190, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 11:
97 can be fit into 930 9 times, resulting in a remainder of 57.
The next digit of our result is 9. 
Result so far: 133880.319
The remainder is 57 after subtracting 873 from 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 12:
97 goes into 570 5 times with a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 133880.3195
The remainder is 85 after subtracting 485 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 13:
When dividing 850 by 97, we get 8 with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 133880.31958
If we take 776 away from 850, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 14:
If we divide 740 by 97, we get 7 and a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 133880.319587
If we take 679 away from 740, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 15:
97 can be fit into 610 6 times, resulting in a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 133880.3195876
Subtracting 582 from 610 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 16:
280 divided by 97 is 2 with a remainder of 86.
Write down 2 as next digit of the result. 
Result so far: 133880.31958762
Subtract 194 from 280 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

In conclusion, the division gives 133880.31958762 with a balance of 8.6e-08.
