82591723 ÷ 77 
We want to figure out the number of times 82591723 can be divided by 77.

Advancing to step 1:
When dividing 8 by 77, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 77

Moving on to step 2:
The number 77 fits into 82 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 77 from 82 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 77

Let's proceed to step 3:
When dividing 55 by 77, we get 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 55, we get 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 77

Step 4:
The number 77 fits into 559 7 times, leaving a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we subtract 539 from 559, we get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 77

Going ahead to step 5:
77 goes into 201 2 times with a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 1072.0
Subtracting 154 from 201 leaves us with 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 77

On to step 6:
77 goes into 477 6 times with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 10726.0
The remainder is 15 after subtracting 462 from 477.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 77

Moving on to step 7:
The number 77 fits into 152 1 times, leaving a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 107261.0
The remainder is 75 after subtracting 77 from 152.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 77

Moving on to step 8:
If we divide 753 by 77, we get 9 and a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 1072619.0
Deduct 693 from 753 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
The number 77 fits into 600 7 times, leaving a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 1072619.7
If we subtract 539 from 600, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 10:
The number 77 fits into 610 7 times, leaving a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 1072619.77
If we subtract 539 from 610, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 1072619.77 and a remainder of 0.071.
