We're dividing 64459908 by 91 
Let's see how many times 91 fits into 64459908.

Let's proceed to step 1:
91 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 91

Going ahead to step 2:
When dividing 64 by 91, we get 0 with 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.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 91

Moving on to step 3:
The number 91 fits into 644 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 637 from 644 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 91

Going ahead to step 4:
The number 91 fits into 75 0 times, leaving a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Deduct 0 from 75 and we're left with 75.
Bring next digit (9) of the dividend behind the 75 and repeat the process: 759 / 91

Let's proceed to step 5:
91 goes into 759 8 times with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 708.0
If we take 728 away from 759, we end up with 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 91

Moving on to step 6:
If we divide 319 by 91, we get 3 and a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 7083.0
If we take 273 away from 319, we end up with 46.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 91

On to step 7:
91 goes into 460 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 70835.0
If we take 455 away from 460, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 91

Going ahead to step 8:
If we divide 58 by 91, we get 0 and a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 708350.0
Subtract 0 from 58 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
91 goes into 580 6 times with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 708350.6
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
91 goes into 340 3 times with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 708350.63
The remainder is 67 after subtracting 273 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 11:
When dividing 670 by 91, we get 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 708350.637
If we subtract 637 from 670, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 12:
If we divide 330 by 91, we get 3 and a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 708350.6373
The remainder is 57 after subtracting 273 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 13:
When dividing 570 by 91, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 708350.63736
If we subtract 546 from 570, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
When dividing 240 by 91, we get 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 708350.637362
If we subtract 182 from 240, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 15:
The number 91 fits into 580 6 times, leaving a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 708350.6373626
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 16:
91 goes into 340 3 times with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 708350.63736263
If we take 273 away from 340, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

In conclusion, the division gives 708350.63736263 with a balance of 6.7e-08.
