77497232 ÷ 855 
We want to figure out the number of times 77497232 can be divided by 855.

Advancing to step 1:
855 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 855

Step 2:
When dividing 77 by 855, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 855

On to step 3:
The number 855 fits into 774 0 times, leaving a remainder of 774.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 774 and we're left with 774.
Take the next digit (9) from the dividend and append it to 774, then repeat: 7749 / 855

On to step 4:
If we divide 7749 by 855, we get 9 and a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7695 from 7749, we get 54.
Include the next digit (7) from the dividend after 54, then repeat: 547 / 855

Moving on to step 5:
855 goes into 547 0 times with a remainder of 547.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtracting 0 from 547 leaves us with 547.
Append the next digit (2) from the dividend to 547 and continue with: 5472 / 855

On to step 6:
When dividing 5472 by 855, we get 6 with a remainder of 342.
Record the quotient 6 as the next digit in the result. 
Result so far: 906.0
If we subtract 5130 from 5472, we get 342.
Grab the next digit (3) from the dividend, add it to 342, then carry on: 3423 / 855

Moving on to step 7:
855 goes into 3423 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 9064.0
Subtract 3420 from 3423 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 855

Step 8:
If we divide 32 by 855, we get 0 and a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 90640.0
Subtract 0 from 32 to get 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 9:
855 can be fit into 320 0 times, resulting in a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 90640.0
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 10:
3200 divided by 855 is 3 with a remainder of 635.
Record the quotient 3 as the next digit in the result. 
Result so far: 90640.03
Subtracting 2565 from 3200 leaves us with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Advancing to step 11:
855 goes into 6350 7 times with a remainder of 365.
Write down 7 as next digit of the result. 
Result so far: 90640.037
If we take 5985 away from 6350, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 12:
If we divide 3650 by 855, we get 4 and a remainder of 230.
The next digit of our result is 4. 
Result so far: 90640.0374
The remainder is 230 after subtracting 3420 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 13:
If we divide 2300 by 855, we get 2 and a remainder of 590.
The next digit of our result is 2. 
Result so far: 90640.03742
Subtracting 1710 from 2300 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 14:
855 goes into 5900 6 times with a remainder of 770.
Record the quotient 6 as the next digit in the result. 
Result so far: 90640.037426
If we subtract 5130 from 5900, we get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Going ahead to step 15:
When dividing 7700 by 855, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 90640.0374269
If we subtract 7695 from 7700, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 16:
855 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 90640.0374269
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 90640.0374269 with a remainder of 5e-08.
