Let's divide 82986793 by 678
Our goal is to divide 82986793 by 678.

Step 1:
If we divide 8 by 678, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 678

Moving on to step 2:
82 divided by 678 is 0 with a remainder of 82.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Include the next digit (9) from the dividend after 82, then repeat: 829 / 678

Advancing to step 3:
678 can be fit into 829 1 times, resulting in a remainder of 151.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 678 from 829 and we're left with 151.
Bring next digit (8) of the dividend behind the 151 and repeat the process: 1518 / 678

Moving on to step 4:
678 goes into 1518 2 times with a remainder of 162.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1356 from 1518 and we're left with 162.
Take the next digit (6) from the dividend and append it to 162, then repeat: 1626 / 678

Moving on to step 5:
678 can be fit into 1626 2 times, resulting in a remainder of 270.
Use 2 as the next digit of our solution. 
Result so far: 122.0
Subtract 1356 from 1626 to get 270.
Bring next digit (7) of the dividend behind the 270 and repeat the process: 2707 / 678

Moving on to step 6:
When dividing 2707 by 678, we get 3 with a remainder of 673.
Record the quotient 3 as the next digit in the result. 
Result so far: 1223.0
Deduct 2034 from 2707 and we're left with 673.
Grab the next digit (9) from the dividend, add it to 673, then carry on: 6739 / 678

Step 7:
When dividing 6739 by 678, we get 9 with a remainder of 637.
Record the quotient 9 as the next digit in the result. 
Result so far: 12239.0
If we subtract 6102 from 6739, we get 637.
Bring next digit (3) of the dividend behind the 637 and repeat the process: 6373 / 678

Going ahead to step 8:
678 can be fit into 6373 9 times, resulting in a remainder of 271.
Write down 9 as next digit of the result. 
Result so far: 122399.0
If we subtract 6102 from 6373, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 9:
The number 678 fits into 2710 3 times, leaving a remainder of 676.
Put 3 as the next digit of the answer. 
Result so far: 122399.3
If we subtract 2034 from 2710, we get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Let's proceed to step 10:
678 goes into 6760 9 times with a remainder of 658.
Put 9 as the next digit of the answer. 
Result so far: 122399.39
If we subtract 6102 from 6760, we get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Moving on to step 11:
678 can be fit into 6580 9 times, resulting in a remainder of 478.
Use 9 as the next digit of our solution. 
Result so far: 122399.399
If we subtract 6102 from 6580, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

After the division, we end up with 122399.399 and a remainder of 0.0478.
