We look at the division of 99408034 by 86 
We want to figure out the number of times 99408034 can be divided by 86.

Moving on to step 1:
The number 86 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 86

Going ahead to step 2:
When dividing 99 by 86, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 86 from 99 to get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 86

Let's proceed to step 3:
134 divided by 86 is 1 with a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 86 from 134 leaves us with 48.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 86

Moving on to step 4:
When dividing 480 by 86, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Subtracting 430 from 480 leaves us with 50.
Include the next digit (8) from the dividend after 50, then repeat: 508 / 86

Going ahead to step 5:
508 divided by 86 is 5 with a remainder of 78.
Use 5 as the next digit of our solution. 
Result so far: 1155.0
Subtract 430 from 508 to get 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 86

Step 6:
When dividing 780 by 86, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 11559.0
If we subtract 774 from 780, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 86

Step 7:
The number 86 fits into 63 0 times, leaving a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 115590.0
Subtracting 0 from 63 leaves us with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 86

On to step 8:
634 divided by 86 is 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 1155907.0
Deduct 602 from 634 and we're left 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.

Step 9:
When dividing 320 by 86, we get 3 with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 1155907.3
Subtracting 258 from 320 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
The number 86 fits into 620 7 times, leaving a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 1155907.37
The remainder is 18 after subtracting 602 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
The number 86 fits into 180 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 1155907.372
Subtracting 172 from 180 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
80 divided by 86 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 1155907.372
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
86 can be fit into 800 9 times, resulting in a remainder of 26.
The next digit of our result is 9. 
Result so far: 1155907.37209
Deduct 774 from 800 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
If we divide 260 by 86, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 1155907.372093
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 15:
The number 86 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 1155907.372093
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 16:
86 can be fit into 200 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 1155907.37209302
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 1155907.37209302 with a remainder of 2.8e-08.
