853878 ÷ 91 
Our goal is to divide 853878 by 91.

Advancing to step 1:
91 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 91

Let's proceed to step 2:
91 can be fit into 85 0 times, resulting in a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Append the next digit (3) from the dividend to 85 and continue with: 853 / 91

Advancing to step 3:
91 goes into 853 9 times with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 819 from 853 to get 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 91

Let's proceed to step 4:
91 can be fit into 348 3 times, resulting in a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Deduct 273 from 348 and we're left with 75.
Fetch the next digit (7) from the dividend, attach it to 75 and continue: 757 / 91

Let's proceed to step 5:
91 can be fit into 757 8 times, resulting in a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 938.0
Subtracting 728 from 757 leaves us with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 91

On to step 6:
91 can be fit into 298 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 9383.0
Subtracting 273 from 298 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
If we divide 250 by 91, we get 2 and a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 9383.2
The remainder is 68 after subtracting 182 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
The number 91 fits into 680 7 times, leaving a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 9383.27
If we subtract 637 from 680, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
430 divided by 91 is 4 with a remainder of 66.
The next digit of our result is 4. 
Result so far: 9383.274
Subtracting 364 from 430 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
91 goes into 660 7 times with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 9383.2747
The remainder is 23 after subtracting 637 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
When dividing 230 by 91, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 9383.27472
If we take 182 away from 230, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
480 divided by 91 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 9383.274725
The remainder is 25 after subtracting 455 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
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: 9383.2747252
Subtract 182 from 250 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 14:
If we divide 680 by 91, we get 7 and a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 9383.27472527
Subtract 637 from 680 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 9383.27472527 with a remainder of 4.3e-08.
