We divide 680545 by 91
We're looking to find how many times 91 goes into 680545.

Step 1:
91 goes into 6 0 times with 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 (8) from the dividend after 6, then repeat: 68 / 91

Moving on to step 2:
If we divide 68 by 91, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 91

Moving on to step 3:
91 can be fit into 680 7 times, resulting in a remainder of 43.
Put 7 as the next digit of the answer. 
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

Moving on to 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
Deduct 364 from 435 and we're left with 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 91

Going ahead to step 5:
91 can be fit into 714 7 times, resulting in a remainder of 77.
The next digit of our result is 7. 
Result so far: 747.0
Subtract 637 from 714 to get 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 91

Advancing to step 6:
91 goes into 775 8 times with a remainder of 47.
Write down 8 as next digit of the result. 
Result so far: 7478.0
If we take 728 away from 775, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
470 divided by 91 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7478.5
Subtracting 455 from 470 leaves us 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.

Advancing to step 8:
The number 91 fits into 150 1 times, leaving a remainder of 59.
The next digit of our result is 1. 
Result so far: 7478.51
If we subtract 91 from 150, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
91 can be fit into 590 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 7478.516
If we take 546 away from 590, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
If we divide 440 by 91, we get 4 and a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 7478.5164
Subtracting 364 from 440 leaves us 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.

Going ahead to step 11:
91 can be fit into 760 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 7478.51648
The remainder is 32 after subtracting 728 from 760.
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 12:
The number 91 fits into 320 3 times, leaving a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 7478.516483
If we take 273 away from 320, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
91 can be fit into 470 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 7478.5164835
If we take 455 away from 470, we end up 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.

Let's proceed to step 14:
91 goes into 150 1 times with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 7478.51648351
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.

The final result is 7478.51648351 with a remainder of 5.9e-08.
