680557 divided by 91 
Let's see how many times 91 fits into 680557.

Let's proceed to step 1:
The number 91 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 91

Going ahead to step 2:
68 divided by 91 is 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 91

Going ahead to step 3:
When dividing 680 by 91, we get 7 with a remainder of 43.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 637 from 680 leaves us with 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 91

Step 4:
91 can be fit into 435 4 times, resulting in a remainder of 71.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
If we subtract 364 from 435, we get 71.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 91

Let's proceed to step 5:
91 goes into 715 7 times with a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 747.0
If we take 637 away from 715, we end up with 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 91

Going ahead to step 6:
787 divided by 91 is 8 with a remainder of 59.
Write down 8 as next digit of the result. 
Result so far: 7478.0
Subtracting 728 from 787 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
91 can be fit into 590 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 7478.6
The remainder is 44 after subtracting 546 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
440 divided by 91 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 7478.64
The remainder is 76 after subtracting 364 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
The number 91 fits into 760 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 7478.648
Deduct 728 from 760 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
When dividing 320 by 91, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 7478.6483
The remainder is 47 after subtracting 273 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 11:
If we divide 470 by 91, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 7478.64835
Deduct 455 from 470 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
When dividing 150 by 91, we get 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 7478.648351
Subtracting 91 from 150 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 13:
The number 91 fits into 590 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 7478.6483516
If we subtract 546 from 590, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
When dividing 440 by 91, we get 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 7478.64835164
If we take 364 away from 440, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 7478.64835164 with a balance of 7.6e-08.
