We look at the division of 431834 by 91 
Let's see how many times 91 fits into 431834.

Moving on to step 1:
91 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 91

Let's proceed to step 2:
91 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 91

Moving on to step 3:
If we divide 431 by 91, we get 4 and a remainder of 67.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 364 from 431, we get 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 91

Going ahead to step 4:
678 divided by 91 is 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 637 away from 678, we end up with 41.
Take the next digit (3) from the dividend and append it to 41, then repeat: 413 / 91

On to step 5:
91 can be fit into 413 4 times, resulting in a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 474.0
The remainder is 49 after subtracting 364 from 413.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 91

On to step 6:
When dividing 494 by 91, we get 5 with a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 4745.0
The remainder is 39 after subtracting 455 from 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
The number 91 fits into 390 4 times, leaving a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 4745.4
Subtract 364 from 390 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
If we divide 260 by 91, we get 2 and a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 4745.42
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.

On to step 9:
When dividing 780 by 91, we get 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 4745.428
The remainder is 52 after subtracting 728 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
91 goes into 520 5 times with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 4745.4285
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.

Let's proceed to step 11:
If we divide 650 by 91, we get 7 and a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 4745.42857
The remainder is 13 after subtracting 637 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
The number 91 fits into 130 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 4745.428571
Subtract 91 from 130 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 13:
91 can be fit into 390 4 times, resulting in a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 4745.4285714
If we take 364 away from 390, 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 14:
91 goes into 260 2 times with a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 4745.42857142
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.

Our division results in 4745.42857142 with a remaining 7.8e-08.
