389042 ÷ 91 
Let's see how many times 91 fits into 389042.

Step 1:
91 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 91

On to step 2:
91 can be fit into 38 0 times, resulting in a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 91

On to step 3:
When dividing 389 by 91, we get 4 with a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 364 from 389 leaves us with 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 91

On to step 4:
91 can be fit into 250 2 times, resulting in a remainder of 68.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 68 after subtracting 182 from 250.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 91

Going ahead to step 5:
When dividing 684 by 91, we get 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 427.0
The remainder is 47 after subtracting 637 from 684.
Include the next digit (2) from the dividend after 47, then repeat: 472 / 91

Advancing to step 6:
91 can be fit into 472 5 times, resulting in a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 4275.0
Deduct 455 from 472 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
91 can be fit into 170 1 times, resulting in a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 4275.1
The remainder is 79 after subtracting 91 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 8:
When dividing 790 by 91, we get 8 with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 4275.18
Subtracting 728 from 790 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
91 can be fit into 620 6 times, resulting in a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 4275.186
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
The number 91 fits into 740 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 4275.1868
Subtracting 728 from 740 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
120 divided by 91 is 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 4275.18681
The remainder is 29 after subtracting 91 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 12:
If we divide 290 by 91, we get 3 and a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 4275.186813
Subtract 273 from 290 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
91 goes into 170 1 times with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 4275.1868131
The remainder is 79 after subtracting 91 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 14:
When dividing 790 by 91, we get 8 with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 4275.18681318
Subtracting 728 from 790 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 4275.18681318 with a remainder of 6.2e-08.
