85478023 ÷ 11 
Our goal is to divide 85478023 by 11.

Advancing to step 1:
11 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 11

Moving on to step 2:
The number 11 fits into 85 7 times, leaving a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 77 from 85 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 11

Moving on to step 3:
11 goes into 84 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
The remainder is 7 after subtracting 77 from 84.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 11

Moving on to step 4:
The number 11 fits into 77 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 777.0
The remainder is 0 after subtracting 77 from 77.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 11

Step 5:
If we divide 8 by 11, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 7770.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 11

Let's proceed to step 6:
If we divide 80 by 11, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 77707.0
If we take 77 away from 80, we end up with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 11

On to step 7:
If we divide 32 by 11, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 777072.0
Deduct 22 from 32 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 11

Advancing to step 8:
The number 11 fits into 103 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 7770729.0
Subtracting 99 from 103 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
The number 11 fits into 40 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 7770729.3
Subtract 33 from 40 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
11 goes into 70 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 7770729.36
The remainder is 4 after subtracting 66 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
11 can be fit into 40 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 7770729.363
Deduct 33 from 40 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
The number 11 fits into 70 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 7770729.3636
If we take 66 away from 70, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
40 divided by 11 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 7770729.36363
Subtracting 33 from 40 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
11 can be fit into 70 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 7770729.363636
The remainder is 4 after subtracting 66 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 15:
The number 11 fits into 40 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 7770729.3636363
Subtracting 33 from 40 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 16:
When dividing 70 by 11, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 7770729.36363636
The remainder is 4 after subtracting 66 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 7770729.36363636 and a remainder of 4e-09.
