We're dividing 78477790 by 720 
Let's see how many times 720 fits into 78477790.

On to step 1:
When dividing 7 by 720, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 720

Advancing to step 2:
When dividing 78 by 720, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 720

Let's proceed to step 3:
When dividing 784 by 720, we get 1 with a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 720 from 784 to get 64.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 720

Moving on to step 4:
When dividing 647 by 720, we get 0 with a remainder of 647.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 647 and we're left with 647.
Grab the next digit (7) from the dividend, add it to 647, then carry on: 6477 / 720

Going ahead to step 5:
720 goes into 6477 8 times with a remainder of 717.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we subtract 5760 from 6477, we get 717.
Take the next digit (7) from the dividend and append it to 717, then repeat: 7177 / 720

Step 6:
7177 divided by 720 is 9 with a remainder of 697.
The number 9 becomes the next digit in our result. 
Result so far: 1089.0
If we take 6480 away from 7177, we end up with 697.
Include the next digit (9) from the dividend after 697, then repeat: 6979 / 720

Going ahead to step 7:
The number 720 fits into 6979 9 times, leaving a remainder of 499.
The number 9 becomes the next digit in our result. 
Result so far: 10899.0
Subtracting 6480 from 6979 leaves us with 499.
Fetch the next digit (0) from the dividend, attach it to 499 and continue: 4990 / 720

Step 8:
720 goes into 4990 6 times with a remainder of 670.
Use 6 as the next digit of our solution. 
Result so far: 108996.0
If we subtract 4320 from 4990, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 9:
When dividing 6700 by 720, we get 9 with a remainder of 220.
Record the quotient 9 as the next digit in the result. 
Result so far: 108996.9
If we subtract 6480 from 6700, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
720 goes into 2200 3 times with a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 108996.93
If we take 2160 away from 2200, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
When dividing 400 by 720, we get 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 108996.93
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 12:
720 goes into 4000 5 times with a remainder of 400.
Write down 5 as next digit of the result. 
Result so far: 108996.9305
If we subtract 3600 from 4000, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
The number 720 fits into 4000 5 times, leaving a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 108996.93055
Subtract 3600 from 4000 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 108996.93055 with a remainder of 0.0004.
