We're dividing 759980 by 91 
Our goal is to divide 759980 by 91.

On to step 1:
When dividing 7 by 91, we get 0 with 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.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 91

Moving on to step 2:
When dividing 75 by 91, we get 0 with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 91

Advancing to step 3:
759 divided by 91 is 8 with a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 728 from 759, we get 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 91

Moving on to step 4:
319 divided by 91 is 3 with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtracting 273 from 319 leaves us with 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 91

Step 5:
When dividing 468 by 91, we get 5 with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 835.0
Subtracting 455 from 468 leaves us with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 91

Step 6:
91 goes into 130 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 8351.0
Deduct 91 from 130 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
When dividing 390 by 91, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 8351.4
Deduct 364 from 390 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
The number 91 fits into 260 2 times, leaving a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 8351.42
The remainder is 78 after subtracting 182 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
780 divided by 91 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 8351.428
The remainder is 52 after subtracting 728 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
When dividing 520 by 91, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 8351.4285
If we subtract 455 from 520, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
The number 91 fits into 650 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 8351.42857
Subtract 637 from 650 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
130 divided by 91 is 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 8351.428571
Deduct 91 from 130 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 13:
If we divide 390 by 91, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 8351.4285714
If we take 364 away from 390, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
When dividing 260 by 91, we get 2 with a remainder of 78.
The next digit of our result is 2. 
Result so far: 8351.42857142
If we take 182 away from 260, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 8351.42857142 and a remainder of 7.8e-08.
