We divide 580485 by 91
We want to figure out the number of times 580485 can be divided by 91.

Step 1:
If we divide 5 by 91, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 91

Going ahead to step 2:
91 goes into 58 0 times with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 91

Going ahead to step 3:
91 goes into 580 6 times with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 546 from 580, we get 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 91

Advancing to step 4:
If we divide 344 by 91, we get 3 and a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 63.0
Deduct 273 from 344 and we're left with 71.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 91

Going ahead to step 5:
91 goes into 718 7 times with a remainder of 81.
Write down 7 as next digit of the result. 
Result so far: 637.0
If we subtract 637 from 718, we get 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 91

On to step 6:
If we divide 815 by 91, we get 8 and a remainder of 87.
Record the quotient 8 as the next digit in the result. 
Result so far: 6378.0
Subtracting 728 from 815 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 7:
870 divided by 91 is 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 6378.9
If we subtract 819 from 870, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 8:
91 goes into 510 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 6378.95
Subtracting 455 from 510 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 9:
When dividing 550 by 91, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 6378.956
If we subtract 546 from 550, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
91 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6378.956
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
91 can be fit into 400 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 6378.95604
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
When dividing 360 by 91, we get 3 with a remainder of 87.
The next digit of our result is 3. 
Result so far: 6378.956043
Deduct 273 from 360 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 13:
When dividing 870 by 91, we get 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 6378.9560439
The remainder is 51 after subtracting 819 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 14:
91 can be fit into 510 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 6378.95604395
The remainder is 55 after subtracting 455 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 6378.95604395 with a remaining 5.5e-08.
