84678231 ÷ 775 
We want to divide 84678231 by 775.

Step 1:
If we divide 8 by 775, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 775

On to step 2:
84 divided by 775 is 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Append the next digit (6) from the dividend to 84 and continue with: 846 / 775

Step 3:
When dividing 846 by 775, we get 1 with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 71 after subtracting 775 from 846.
Include the next digit (7) from the dividend after 71, then repeat: 717 / 775

On to step 4:
When dividing 717 by 775, we get 0 with a remainder of 717.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 717 to get 717.
Grab the next digit (8) from the dividend, add it to 717, then carry on: 7178 / 775

On to step 5:
7178 divided by 775 is 9 with a remainder of 203.
Write down 9 as next digit of the result. 
Result so far: 109.0
The remainder is 203 after subtracting 6975 from 7178.
Append the next digit (2) from the dividend to 203 and continue with: 2032 / 775

Moving on to step 6:
When dividing 2032 by 775, we get 2 with a remainder of 482.
The number 2 becomes the next digit in our result. 
Result so far: 1092.0
Subtracting 1550 from 2032 leaves us with 482.
Fetch the next digit (3) from the dividend, attach it to 482 and continue: 4823 / 775

Going ahead to step 7:
If we divide 4823 by 775, we get 6 and a remainder of 173.
Put 6 as the next digit of the answer. 
Result so far: 10926.0
Deduct 4650 from 4823 and we're left with 173.
Grab the next digit (1) from the dividend, add it to 173, then carry on: 1731 / 775

Step 8:
When dividing 1731 by 775, we get 2 with a remainder of 181.
The next digit of our result is 2. 
Result so far: 109262.0
Subtracting 1550 from 1731 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 9:
When dividing 1810 by 775, we get 2 with a remainder of 260.
Write down 2 as next digit of the result. 
Result so far: 109262.2
Subtracting 1550 from 1810 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
The number 775 fits into 2600 3 times, leaving a remainder of 275.
Record the quotient 3 as the next digit in the result. 
Result so far: 109262.23
The remainder is 275 after subtracting 2325 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 11:
775 goes into 2750 3 times with a remainder of 425.
Use 3 as the next digit of our solution. 
Result so far: 109262.233
If we take 2325 away from 2750, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

The quotient of the division is 109262.233, and the remainder is 0.0425.
