303372 divided by 86 
We want to figure out the number of times 303372 can be divided by 86.

Let's proceed to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 86

Going ahead to step 2:
86 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 86

Moving on to step 3:
86 can be fit into 303 3 times, resulting in a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 258 away from 303, we end up with 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 86

Let's proceed to step 4:
453 divided by 86 is 5 with a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 430 from 453 leaves us with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 86

Advancing to step 5:
If we divide 237 by 86, we get 2 and a remainder of 65.
The number 2 becomes the next digit in our result. 
Result so far: 352.0
Subtract 172 from 237 to get 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 86

Let's proceed to step 6:
86 goes into 652 7 times with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 3527.0
Subtract 602 from 652 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
86 can be fit into 500 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 3527.5
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
If we divide 700 by 86, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 3527.58
If we subtract 688 from 700, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
120 divided by 86 is 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 3527.581
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
If we divide 340 by 86, we get 3 and a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 3527.5813
If we subtract 258 from 340, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 11:
86 can be fit into 820 9 times, resulting in a remainder of 46.
The next digit of our result is 9. 
Result so far: 3527.58139
Deduct 774 from 820 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
460 divided by 86 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 3527.581395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
If we divide 300 by 86, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 3527.5813953
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
The number 86 fits into 420 4 times, leaving a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 3527.58139534
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 3527.58139534, with a leftover of 7.6e-08.
