We're dividing 724245 by 77 
We want to figure out the number of times 724245 can be divided by 77.

Moving on to step 1:
The number 77 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 77

Let's proceed to step 2:
77 goes into 72 0 times with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (4) from the dividend after 72, then repeat: 724 / 77

On to step 3:
If we divide 724 by 77, we get 9 and a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 693 away from 724, we end up with 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 77

Advancing to step 4:
When dividing 312 by 77, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 94.0
The remainder is 4 after subtracting 308 from 312.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 77

Moving on to step 5:
77 goes into 44 0 times with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 940.0
The remainder is 44 after subtracting 0 from 44.
Take the next digit (5) from the dividend and append it to 44, then repeat: 445 / 77

Going ahead to step 6:
The number 77 fits into 445 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 9405.0
Subtracting 385 from 445 leaves us 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 7:
The number 77 fits into 600 7 times, leaving a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 9405.7
If we take 539 away from 600, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 8:
When dividing 610 by 77, we get 7 with a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 9405.77
Deduct 539 from 610 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 9405.77 and a remainder of 0.071.
