We divide 300623 by 86
We want to figure out the number of times 300623 can be divided by 86.

Going ahead to step 1:
86 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 86

Moving on to step 2:
When dividing 30 by 86, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 86

Step 3:
If we divide 300 by 86, we get 3 and a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 42 after subtracting 258 from 300.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 86

Step 4:
If we divide 426 by 86, we get 4 and a remainder of 82.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 82 after subtracting 344 from 426.
Include the next digit (2) from the dividend after 82, then repeat: 822 / 86

Let's proceed to step 5:
The number 86 fits into 822 9 times, leaving a remainder of 48.
The next digit of our result is 9. 
Result so far: 349.0
Subtracting 774 from 822 leaves us with 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 86

Step 6:
86 goes into 483 5 times with a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 3495.0
If we subtract 430 from 483, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
The number 86 fits into 530 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 3495.6
Subtracting 516 from 530 leaves us 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.

On to step 8:
86 can be fit into 140 1 times, resulting in a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 3495.61
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
When dividing 540 by 86, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 3495.616
If we subtract 516 from 540, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
When dividing 240 by 86, we get 2 with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 3495.6162
If we take 172 away from 240, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
When dividing 680 by 86, we get 7 with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 3495.61627
If we subtract 602 from 680, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 12:
When dividing 780 by 86, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 3495.616279
If we take 774 away from 780, we end up 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.

On to step 13:
When dividing 60 by 86, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 3495.616279
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
600 divided by 86 is 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 3495.61627906
If we take 516 away from 600, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 3495.61627906, with a leftover of 8.4e-08.
