We're dividing 486586 by 91 
We want to divide 486586 by 91.

Going ahead to step 1:
If we divide 4 by 91, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 91

Step 2:
48 divided by 91 is 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 91

Let's proceed to step 3:
91 goes into 486 5 times with a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 455 from 486 and we're left with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 91

Going ahead to step 4:
If we divide 315 by 91, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 53.0
The remainder is 42 after subtracting 273 from 315.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 91

Let's proceed to step 5:
When dividing 428 by 91, we get 4 with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 534.0
Deduct 364 from 428 and we're left with 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 91

Going ahead to step 6:
646 divided by 91 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 5347.0
Deduct 637 from 646 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 91, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 5347.0
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 8:
The number 91 fits into 900 9 times, leaving a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 5347.09
Subtract 819 from 900 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
810 divided by 91 is 8 with a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 5347.098
If we subtract 728 from 810, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 10:
820 divided by 91 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 5347.0989
The remainder is 1 after subtracting 819 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
If we divide 10 by 91, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5347.0989
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
If we divide 100 by 91, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 5347.098901
If we take 91 away from 100, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
90 divided by 91 is 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 5347.098901
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 14:
91 can be fit into 900 9 times, resulting in a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 5347.09890109
The remainder is 81 after subtracting 819 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

In conclusion, the division gives 5347.09890109 with a balance of 8.1e-08.
