97997918 ÷ 86 
We want to figure out the number of times 97997918 can be divided by 86.

On to step 1:
86 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 86

Moving on to step 2:
86 can be fit into 97 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 86 from 97 to get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 86

Going ahead to step 3:
When dividing 119 by 86, we get 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 86 from 119 leaves us with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 86

Going ahead to step 4:
339 divided by 86 is 3 with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 113.0
Subtract 258 from 339 to get 81.
Fetch the next digit (7) from the dividend, attach it to 81 and continue: 817 / 86

On to step 5:
86 goes into 817 9 times with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 1139.0
If we take 774 away from 817, we end up with 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 86

Let's proceed to step 6:
If we divide 439 by 86, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 11395.0
The remainder is 9 after subtracting 430 from 439.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 86

Advancing to step 7:
86 can be fit into 91 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 113951.0
Subtracting 86 from 91 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 86

Moving on to step 8:
58 divided by 86 is 0 with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 1139510.0
The remainder is 58 after subtracting 0 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
580 divided by 86 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 1139510.6
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 1139510.67
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 1139510.674
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
86 can be fit into 360 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1139510.6744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 1139510.6744 with a remaining 0.00016.
