We look at the division of 78240552 by 693 
Let's see how many times 693 fits into 78240552.

Going ahead to step 1:
7 divided by 693 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 693

Let's proceed to step 2:
78 divided by 693 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 693

Advancing to step 3:
The number 693 fits into 782 1 times, leaving a remainder of 89.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 693 from 782, we get 89.
Bring next digit (4) of the dividend behind the 89 and repeat the process: 894 / 693

Advancing to step 4:
The number 693 fits into 894 1 times, leaving a remainder of 201.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 693 from 894 and we're left with 201.
Include the next digit (0) from the dividend after 201, then repeat: 2010 / 693

Let's proceed to step 5:
If we divide 2010 by 693, we get 2 and a remainder of 624.
The next digit of our result is 2. 
Result so far: 112.0
If we take 1386 away from 2010, we end up with 624.
Append the next digit (5) from the dividend to 624 and continue with: 6245 / 693

Advancing to step 6:
693 goes into 6245 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 1129.0
The remainder is 8 after subtracting 6237 from 6245.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 693

Advancing to step 7:
When dividing 85 by 693, we get 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 11290.0
If we subtract 0 from 85, we get 85.
Grab the next digit (2) from the dividend, add it to 85, then carry on: 852 / 693

Advancing to step 8:
693 goes into 852 1 times with a remainder of 159.
Write down 1 as next digit of the result. 
Result so far: 112901.0
If we subtract 693 from 852, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 9:
693 goes into 1590 2 times with a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 112901.2
Subtract 1386 from 1590 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 10:
When dividing 2040 by 693, we get 2 with a remainder of 654.
Record the quotient 2 as the next digit in the result. 
Result so far: 112901.22
Subtract 1386 from 2040 to get 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

After the division, we end up with 112901.22 and a remainder of 0.654.
