64505792 ÷ 855 
We want to divide 64505792 by 855.

Moving on to step 1:
6 divided by 855 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 855

Step 2:
If we divide 64 by 855, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 855

On to step 3:
When dividing 645 by 855, we get 0 with a remainder of 645.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 645 and we're left with 645.
Fetch the next digit (0) from the dividend, attach it to 645 and continue: 6450 / 855

On to step 4:
6450 divided by 855 is 7 with a remainder of 465.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 5985 from 6450, we get 465.
Fetch the next digit (5) from the dividend, attach it to 465 and continue: 4655 / 855

Let's proceed to step 5:
855 can be fit into 4655 5 times, resulting in a remainder of 380.
Write down 5 as next digit of the result. 
Result so far: 75.0
Deduct 4275 from 4655 and we're left with 380.
Append the next digit (7) from the dividend to 380 and continue with: 3807 / 855

Moving on to step 6:
855 goes into 3807 4 times with a remainder of 387.
The next digit of our result is 4. 
Result so far: 754.0
If we take 3420 away from 3807, we end up with 387.
Bring next digit (9) of the dividend behind the 387 and repeat the process: 3879 / 855

Moving on to step 7:
If we divide 3879 by 855, we get 4 and a remainder of 459.
Record the quotient 4 as the next digit in the result. 
Result so far: 7544.0
Deduct 3420 from 3879 and we're left with 459.
Grab the next digit (2) from the dividend, add it to 459, then carry on: 4592 / 855

Step 8:
The number 855 fits into 4592 5 times, leaving a remainder of 317.
Use 5 as the next digit of our solution. 
Result so far: 75445.0
Deduct 4275 from 4592 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Moving on to step 9:
855 goes into 3170 3 times with a remainder of 605.
Record the quotient 3 as the next digit in the result. 
Result so far: 75445.3
Subtract 2565 from 3170 to get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Step 10:
When dividing 6050 by 855, we get 7 with a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 75445.37
If we take 5985 away from 6050, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 11:
If we divide 650 by 855, we get 0 and a remainder of 650.
Put 0 as the next digit of the answer. 
Result so far: 75445.37
Deduct 0 from 650 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 12:
The number 855 fits into 6500 7 times, leaving a remainder of 515.
The next digit of our result is 7. 
Result so far: 75445.3707
Subtracting 5985 from 6500 leaves us with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 13:
855 goes into 5150 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 75445.37076
If we take 5130 away from 5150, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
If we divide 200 by 855, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 75445.37076
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 15:
855 goes into 2000 2 times with a remainder of 290.
Write down 2 as next digit of the result. 
Result so far: 75445.3707602
If we subtract 1710 from 2000, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 16:
The number 855 fits into 2900 3 times, leaving a remainder of 335.
The next digit of our result is 3. 
Result so far: 75445.37076023
Subtracting 2565 from 2900 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The final outcome is 75445.37076023, with a leftover of 3.35e-07.
