We divide 340821 by 91
We're looking to find how many times 91 goes into 340821.

Going ahead to step 1:
The number 91 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 91

Advancing to step 2:
If we divide 34 by 91, we get 0 and a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 91

On to step 3:
When dividing 340 by 91, we get 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 273 from 340, we get 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 91

On to step 4:
The number 91 fits into 678 7 times, leaving a remainder of 41.
The next digit of our result is 7. 
Result so far: 37.0
Subtracting 637 from 678 leaves us with 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 91

On to step 5:
91 can be fit into 412 4 times, resulting in a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 374.0
Subtracting 364 from 412 leaves us with 48.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 91

Step 6:
The number 91 fits into 481 5 times, leaving a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 3745.0
If we take 455 away from 481, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
260 divided by 91 is 2 with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 3745.2
If we subtract 182 from 260, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 8:
The number 91 fits into 780 8 times, leaving a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 3745.28
Subtract 728 from 780 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
91 goes into 520 5 times with a remainder of 65.
The next digit of our result is 5. 
Result so far: 3745.285
The remainder is 65 after subtracting 455 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 10:
When dividing 650 by 91, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 3745.2857
Subtract 637 from 650 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 11:
91 can be fit into 130 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 3745.28571
The remainder is 39 after subtracting 91 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 12:
390 divided by 91 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 3745.285714
Subtracting 364 from 390 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
260 divided by 91 is 2 with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 3745.2857142
The remainder is 78 after subtracting 182 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 14:
780 divided by 91 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 3745.28571428
Deduct 728 from 780 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 3745.28571428, with a leftover of 5.2e-08.
