We look at the division of 290944 by 86 
We want to figure out the number of times 290944 can be divided by 86.

On to step 1:
The number 86 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 86

Moving on to step 2:
86 goes into 29 0 times with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 86

Going ahead to step 3:
The number 86 fits into 290 3 times, leaving a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 258 from 290 leaves us with 32.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 86

Let's proceed to step 4:
86 can be fit into 329 3 times, resulting in a remainder of 71.
The next digit of our result is 3. 
Result so far: 33.0
If we subtract 258 from 329, we get 71.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 86

On to step 5:
When dividing 714 by 86, we get 8 with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 338.0
If we take 688 away from 714, we end up with 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 86

On to step 6:
If we divide 264 by 86, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3383.0
The remainder is 6 after subtracting 258 from 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 86 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 3383.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
If we divide 600 by 86, we get 6 and a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 3383.06
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.

Going ahead to step 9:
When dividing 840 by 86, we get 9 with a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 3383.069
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
660 divided by 86 is 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 3383.0697
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
The number 86 fits into 580 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 3383.06976
Subtracting 516 from 580 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
86 can be fit into 640 7 times, resulting in a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 3383.069767
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
When dividing 380 by 86, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 3383.0697674
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
The number 86 fits into 360 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 3383.06976744
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.

The final result is 3383.06976744 with a remainder of 1.6e-08.
