We look at the division of 78240448 by 693 
Our goal is to divide 78240448 by 693.

Going ahead to step 1:
693 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 693

On to step 2:
The number 693 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 693

On to step 3:
The number 693 fits into 782 1 times, leaving a remainder of 89.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 693 from 782 and we're left with 89.
Bring next digit (4) of the dividend behind the 89 and repeat the process: 894 / 693

Moving on to step 4:
693 goes into 894 1 times with a remainder of 201.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 693 from 894 and we're left with 201.
Take the next digit (0) from the dividend and append it to 201, then repeat: 2010 / 693

Let's proceed to step 5:
693 goes into 2010 2 times with a remainder of 624.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtract 1386 from 2010 to get 624.
Include the next digit (4) from the dividend after 624, then repeat: 6244 / 693

Let's proceed to step 6:
When dividing 6244 by 693, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 1129.0
If we subtract 6237 from 6244, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 693

Going ahead to step 7:
The number 693 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 11290.0
If we subtract 0 from 74, we get 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 693

On to step 8:
748 divided by 693 is 1 with a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 112901.0
If we take 693 away from 748, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
When dividing 550 by 693, we get 0 with a remainder of 550.
Write down 0 as next digit of the result. 
Result so far: 112901.0
If we take 0 away from 550, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 10:
The number 693 fits into 5500 7 times, leaving a remainder of 649.
Use 7 as the next digit of our solution. 
Result so far: 112901.07
If we take 4851 away from 5500, we end up with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Advancing to step 11:
If we divide 6490 by 693, we get 9 and a remainder of 253.
Write down 9 as next digit of the result. 
Result so far: 112901.079
If we subtract 6237 from 6490, we get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 12:
2530 divided by 693 is 3 with a remainder of 451.
Record the quotient 3 as the next digit in the result. 
Result so far: 112901.0793
Deduct 2079 from 2530 and we're left with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Moving on to step 13:
693 goes into 4510 6 times with a remainder of 352.
The next digit of our result is 6. 
Result so far: 112901.07936
If we subtract 4158 from 4510, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 14:
If we divide 3520 by 693, we get 5 and a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 112901.079365
Subtracting 3465 from 3520 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 15:
If we divide 550 by 693, we get 0 and a remainder of 550.
Put 0 as the next digit of the answer. 
Result so far: 112901.079365
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 16:
5500 divided by 693 is 7 with a remainder of 649.
Put 7 as the next digit of the answer. 
Result so far: 112901.07936507
The remainder is 649 after subtracting 4851 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

The quotient of the division is 112901.07936507, and the remainder is 6.49e-07.
