Let's divide 301991 by 91
Let's see how many times 91 fits into 301991.

Step 1:
If we divide 3 by 91, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 91

Moving on to step 2:
91 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 91

On to step 3:
91 can be fit into 301 3 times, resulting in a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 273 from 301 and we're left with 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 91

Moving on to step 4:
91 goes into 289 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 273 away from 289, we end up with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 91

Advancing to step 5:
169 divided by 91 is 1 with a remainder of 78.
Put 1 as the next digit of the answer. 
Result so far: 331.0
If we subtract 91 from 169, we get 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 91

On to step 6:
When dividing 781 by 91, we get 8 with a remainder of 53.
The next digit of our result is 8. 
Result so far: 3318.0
Subtracting 728 from 781 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
530 divided by 91 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 3318.5
If we subtract 455 from 530, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 8:
If we divide 750 by 91, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 3318.58
Deduct 728 from 750 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
91 can be fit into 220 2 times, resulting in a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 3318.582
Subtracting 182 from 220 leaves us 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.

On to step 10:
91 can be fit into 380 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 3318.5824
Subtracting 364 from 380 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
91 goes into 160 1 times with a remainder of 69.
The next digit of our result is 1. 
Result so far: 3318.58241
Deduct 91 from 160 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 12:
The number 91 fits into 690 7 times, leaving a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 3318.582417
The remainder is 53 after subtracting 637 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 13:
If we divide 530 by 91, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 3318.5824175
Subtracting 455 from 530 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 14:
The number 91 fits into 750 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 3318.58241758
If we subtract 728 from 750, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 3318.58241758 with a remaining 2.2e-08.
