We look at the division of 289221 by 86 
We want to figure out the number of times 289221 can be divided by 86.

Moving on to step 1:
2 divided by 86 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 86

On to step 2:
When dividing 28 by 86, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 86

Moving on to step 3:
The number 86 fits into 289 3 times, leaving a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 258 from 289 and we're left with 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 86

On to step 4:
86 can be fit into 312 3 times, resulting in a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
The remainder is 54 after subtracting 258 from 312.
Grab the next digit (2) from the dividend, add it to 54, then carry on: 542 / 86

Moving on to step 5:
86 can be fit into 542 6 times, resulting in a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 336.0
If we take 516 away from 542, we end up with 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 86

Advancing to step 6:
If we divide 261 by 86, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3363.0
The remainder is 3 after subtracting 258 from 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
86 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 3363.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
86 can be fit into 300 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 3363.03
If we take 258 away from 300, we end up 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.

Going ahead to step 9:
The number 86 fits into 420 4 times, leaving a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 3363.034
If we take 344 away from 420, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
When dividing 760 by 86, we get 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 3363.0348
If we subtract 688 from 760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 3363.03488
Subtracting 688 from 720 leaves us 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.

The final result is 3363.03488 with a remainder of 3.2e-05.
