We're dividing 351912 by 91 
Let's see how many times 91 fits into 351912.

Moving on to step 1:
3 divided by 91 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 91

Moving on to step 2:
91 can be fit into 35 0 times, resulting in a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 91

Going ahead to step 3:
91 goes into 351 3 times with a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 273 away from 351, we end up with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 91

Step 4:
91 can be fit into 789 8 times, resulting in a remainder of 61.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 728 from 789, we get 61.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 91

Let's proceed to step 5:
611 divided by 91 is 6 with a remainder of 65.
The number 6 becomes the next digit in our result. 
Result so far: 386.0
If we subtract 546 from 611, we get 65.
Take the next digit (2) from the dividend and append it to 65, then repeat: 652 / 91

Advancing to step 6:
The number 91 fits into 652 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 3867.0
The remainder is 15 after subtracting 637 from 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
91 can be fit into 150 1 times, resulting in a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 3867.1
The remainder is 59 after subtracting 91 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 8:
91 goes into 590 6 times with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 3867.16
Subtracting 546 from 590 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
91 goes into 440 4 times with a remainder of 76.
The next digit of our result is 4. 
Result so far: 3867.164
If we subtract 364 from 440, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
91 goes into 760 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 3867.1648
The remainder is 32 after subtracting 728 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
320 divided by 91 is 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 3867.16483
If we take 273 away from 320, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 12:
91 goes into 470 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 3867.164835
If we subtract 455 from 470, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
91 goes into 150 1 times with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 3867.1648351
If we subtract 91 from 150, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 14:
The number 91 fits into 590 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 3867.16483516
If we subtract 546 from 590, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 3867.16483516 with a balance of 4.4e-08.
