Let's divide 538122 by 78
Our goal is to divide 538122 by 78.

Step 1:
5 divided by 78 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 78

Advancing to step 2:
53 divided by 78 is 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 78

Step 3:
538 divided by 78 is 6 with a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 468 from 538, we get 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 78

Advancing to step 4:
When dividing 701 by 78, we get 8 with a remainder of 77.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
If we take 624 away from 701, we end up with 77.
Fetch the next digit (2) from the dividend, attach it to 77 and continue: 772 / 78

Moving on to step 5:
The number 78 fits into 772 9 times, leaving a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 689.0
Deduct 702 from 772 and we're left with 70.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 78

Going ahead to step 6:
If we divide 702 by 78, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 6899.0
Deduct 702 from 702 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
78 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6899.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 78, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6899.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 6899.0, with a leftover of 0.0.
