We're dividing 286439 by 91 
Our goal is to divide 286439 by 91.

Advancing to step 1:
91 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 91

Let's proceed to step 2:
28 divided by 91 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 91

On to step 3:
91 can be fit into 286 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 13 after subtracting 273 from 286.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 91

Going ahead to step 4:
When dividing 134 by 91, we get 1 with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 31.0
The remainder is 43 after subtracting 91 from 134.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 91

Let's proceed to step 5:
The number 91 fits into 433 4 times, leaving a remainder of 69.
Put 4 as the next digit of the answer. 
Result so far: 314.0
Subtracting 364 from 433 leaves us with 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 91

Moving on to step 6:
91 goes into 699 7 times with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 3147.0
Subtract 637 from 699 to get 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 7:
If we divide 620 by 91, we get 6 and a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 3147.6
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 8:
The number 91 fits into 740 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 3147.68
Subtracting 728 from 740 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
The number 91 fits into 120 1 times, leaving a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 3147.681
Subtracting 91 from 120 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 10:
290 divided by 91 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3147.6813
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
The number 91 fits into 170 1 times, leaving a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 3147.68131
Subtract 91 from 170 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 12:
The number 91 fits into 790 8 times, leaving a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 3147.681318
Subtracting 728 from 790 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.

Advancing to step 13:
91 can be fit into 620 6 times, resulting in a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 3147.6813186
The remainder is 74 after subtracting 546 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
If we divide 740 by 91, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 3147.68131868
If we take 728 away from 740, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 3147.68131868 with a balance of 1.2e-08.
