We're dividing 771689 by 91 
Let's see how many times 91 fits into 771689.

Let's proceed to step 1:
91 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 91

On to step 2:
The number 91 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (1) from the dividend after 77, then repeat: 771 / 91

Moving on to step 3:
91 can be fit into 771 8 times, resulting in a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 728 away from 771, we end up with 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 91

Going ahead to step 4:
91 goes into 436 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we take 364 away from 436, we end up with 72.
Append the next digit (8) from the dividend to 72 and continue with: 728 / 91

Step 5:
If we divide 728 by 91, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 848.0
Subtracting 728 from 728 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 91

On to step 6:
91 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 8480.0
Subtracting 0 from 9 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
91 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 8480.0
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 8:
91 can be fit into 900 9 times, resulting in a remainder of 81.
The next digit of our result is 9. 
Result so far: 8480.09
If we take 819 away from 900, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
91 goes into 810 8 times with a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 8480.098
Deduct 728 from 810 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 10:
When dividing 820 by 91, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 8480.0989
Subtract 819 from 820 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
The number 91 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 8480.0989
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 91, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 8480.098901
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
The number 91 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 8480.098901
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 14:
900 divided by 91 is 9 with a remainder of 81.
The next digit of our result is 9. 
Result so far: 8480.09890109
Deduct 819 from 900 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final result is 8480.09890109 with a remainder of 8.1e-08.
