We look at the division of 648359 by 91 
We're looking to find how many times 91 goes into 648359.

Moving on to step 1:
91 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 91

Step 2:
If we divide 64 by 91, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 91

Step 3:
The number 91 fits into 648 7 times, leaving a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 637 from 648 and we're left with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 91

On to step 4:
When dividing 113 by 91, we get 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 71.0
Subtract 91 from 113 to get 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 91

Step 5:
If we divide 225 by 91, we get 2 and a remainder of 43.
The next digit of our result is 2. 
Result so far: 712.0
If we take 182 away from 225, we end up with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 91

Let's proceed to step 6:
91 can be fit into 439 4 times, resulting in a remainder of 75.
Record the quotient 4 as the next digit in the result. 
Result so far: 7124.0
If we subtract 364 from 439, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 7:
If we divide 750 by 91, we get 8 and a remainder of 22.
The next digit of our result is 8. 
Result so far: 7124.8
If we take 728 away from 750, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
The number 91 fits into 220 2 times, leaving a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 7124.82
If we take 182 away from 220, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
The number 91 fits into 380 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 7124.824
Subtract 364 from 380 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
91 can be fit into 160 1 times, resulting in a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 7124.8241
Subtract 91 from 160 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 11:
91 goes into 690 7 times with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 7124.82417
Subtracting 637 from 690 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 12:
If we divide 530 by 91, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 7124.824175
Subtract 455 from 530 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 13:
If we divide 750 by 91, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 7124.8241758
The remainder is 22 after subtracting 728 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
91 can be fit into 220 2 times, resulting in a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 7124.82417582
The remainder is 38 after subtracting 182 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 7124.82417582 with a balance of 3.8e-08.
