76920079 ÷ 839 
Let's see how many times 839 fits into 76920079.

Step 1:
If we divide 7 by 839, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 839

Let's proceed to step 2:
When dividing 76 by 839, we get 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 839

Step 3:
839 goes into 769 0 times with a remainder of 769.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 769 leaves us with 769.
Fetch the next digit (2) from the dividend, attach it to 769 and continue: 7692 / 839

Step 4:
The number 839 fits into 7692 9 times, leaving a remainder of 141.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 141 after subtracting 7551 from 7692.
Take the next digit (0) from the dividend and append it to 141, then repeat: 1410 / 839

Going ahead to step 5:
If we divide 1410 by 839, we get 1 and a remainder of 571.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we subtract 839 from 1410, we get 571.
Grab the next digit (0) from the dividend, add it to 571, then carry on: 5710 / 839

Going ahead to step 6:
If we divide 5710 by 839, we get 6 and a remainder of 676.
Record the quotient 6 as the next digit in the result. 
Result so far: 916.0
If we take 5034 away from 5710, we end up with 676.
Bring next digit (7) of the dividend behind the 676 and repeat the process: 6767 / 839

Advancing to step 7:
When dividing 6767 by 839, we get 8 with a remainder of 55.
The number 8 becomes the next digit in our result. 
Result so far: 9168.0
If we subtract 6712 from 6767, we get 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 839

Going ahead to step 8:
559 divided by 839 is 0 with a remainder of 559.
Write down 0 as next digit of the result. 
Result so far: 91680.0
If we subtract 0 from 559, we get 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Step 9:
839 can be fit into 5590 6 times, resulting in a remainder of 556.
Use 6 as the next digit of our solution. 
Result so far: 91680.6
Deduct 5034 from 5590 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 10:
839 goes into 5560 6 times with a remainder of 526.
Use 6 as the next digit of our solution. 
Result so far: 91680.66
If we take 5034 away from 5560, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

The quotient of the division is 91680.66, and the remainder is 0.526.
