We're dividing 485400 by 91 
We want to divide 485400 by 91.

Moving on to step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 91

Let's proceed to step 2:
91 goes into 48 0 times with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 91

Advancing to step 3:
The number 91 fits into 485 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 455 from 485 leaves us with 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 91

Going ahead to step 4:
The number 91 fits into 304 3 times, leaving a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtract 273 from 304 to get 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 91

On to step 5:
The number 91 fits into 310 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 533.0
Subtracting 273 from 310 leaves us with 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 91

Going ahead to step 6:
370 divided by 91 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 5334.0
Subtract 364 from 370 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
91 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5334.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
If we divide 600 by 91, we get 6 and a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 5334.06
Deduct 546 from 600 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
91 goes into 540 5 times with a remainder of 85.
The next digit of our result is 5. 
Result so far: 5334.065
If we subtract 455 from 540, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 10:
When dividing 850 by 91, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 5334.0659
Deduct 819 from 850 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
91 can be fit into 310 3 times, resulting in a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 5334.06593
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
If we divide 370 by 91, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 5334.065934
Deduct 364 from 370 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
The number 91 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 5334.065934
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
91 goes into 600 6 times with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 5334.06593406
Subtract 546 from 600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 5334.06593406 with a balance of 5.4e-08.
