We look at the division of 724665 by 78 
Let's see how many times 78 fits into 724665.

Step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 78

Moving on to step 2:
The number 78 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Grab the next digit (4) from the dividend, add it to 72, then carry on: 724 / 78

On to step 3:
If we divide 724 by 78, we get 9 and a remainder of 22.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 702 from 724 to get 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 78

Advancing to step 4:
When dividing 226 by 78, we get 2 with a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 92.0
If we take 156 away from 226, we end up with 70.
Fetch the next digit (6) from the dividend, attach it to 70 and continue: 706 / 78

Moving on to step 5:
If we divide 706 by 78, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 929.0
Subtracting 702 from 706 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 78

Let's proceed to step 6:
If we divide 45 by 78, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 9290.0
Deduct 0 from 45 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
The number 78 fits into 450 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 9290.5
Deduct 390 from 450 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
When dividing 600 by 78, we get 7 with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 9290.57
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
78 goes into 540 6 times with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 9290.576
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 9290.5769
Subtracting 702 from 720 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
The number 78 fits into 180 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 9290.57692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
When dividing 240 by 78, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 9290.576923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
If we divide 60 by 78, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 9290.576923
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
78 can be fit into 600 7 times, resulting in a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 9290.57692307
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 9290.57692307, with a leftover of 5.4e-08.
