We look at the division of 687810 by 91 
Let's see how many times 91 fits into 687810.

Going ahead to step 1:
The number 91 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 91

Going ahead to step 2:
91 can be fit into 68 0 times, resulting in a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Fetch the next digit (7) from the dividend, attach it to 68 and continue: 687 / 91

Advancing to step 3:
The number 91 fits into 687 7 times, leaving a remainder of 50.
The next digit of our result is 7. 
Result so far: 7.0
If we take 637 away from 687, we end up with 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 91

Moving on to step 4:
When dividing 508 by 91, we get 5 with a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
The remainder is 53 after subtracting 455 from 508.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 91

Advancing to step 5:
When dividing 531 by 91, we get 5 with a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 755.0
Deduct 455 from 531 and we're left with 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 91

Going ahead to step 6:
When dividing 760 by 91, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 7558.0
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.

Advancing to step 7:
When dividing 320 by 91, we get 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 7558.3
Subtracting 273 from 320 leaves us 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.

Advancing to step 8:
When dividing 470 by 91, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 7558.35
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.

Step 9:
If we divide 150 by 91, we get 1 and a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 7558.351
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.

Going ahead to step 10:
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: 7558.3516
Subtracting 546 from 590 leaves us 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.

Let's proceed to step 11:
91 goes into 440 4 times with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 7558.35164
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.

Going ahead to step 12:
The number 91 fits into 760 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 7558.351648
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.

Going ahead to step 13:
The number 91 fits into 320 3 times, leaving a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 7558.3516483
If we subtract 273 from 320, we get 47.
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 14:
470 divided by 91 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 7558.35164835
If we subtract 455 from 470, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 7558.35164835 with a balance of 1.5e-08.
