Let's divide 278890 by 91
We're looking to find how many times 91 goes into 278890.

Advancing to step 1:
When dividing 2 by 91, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 91

Step 2:
91 can be fit into 27 0 times, resulting in a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 91

Going ahead to step 3:
91 goes into 278 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 273 from 278 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 91

Advancing to step 4:
91 goes into 58 0 times with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 58, we end up with 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 91

Let's proceed to step 5:
91 goes into 589 6 times with a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 306.0
Subtracting 546 from 589 leaves us with 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 91

On to step 6:
91 goes into 430 4 times with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 3064.0
If we take 364 away from 430, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 7:
The number 91 fits into 660 7 times, leaving a remainder of 23.
The next digit of our result is 7. 
Result so far: 3064.7
Deduct 637 from 660 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 8:
If we divide 230 by 91, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 3064.72
If we take 182 away from 230, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
When dividing 480 by 91, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 3064.725
Subtract 455 from 480 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
The number 91 fits into 250 2 times, leaving a remainder of 68.
The next digit of our result is 2. 
Result so far: 3064.7252
Subtracting 182 from 250 leaves us 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.

Let's proceed to step 11:
680 divided by 91 is 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 3064.72527
Subtracting 637 from 680 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 12:
If we divide 430 by 91, we get 4 and a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 3064.725274
If we subtract 364 from 430, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
If we divide 660 by 91, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 3064.7252747
The remainder is 23 after subtracting 637 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 14:
The number 91 fits into 230 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 3064.72527472
Subtract 182 from 230 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 3064.72527472 with a remaining 4.8e-08.
