78580207 ÷ 730 
We want to figure out the number of times 78580207 can be divided by 730.

Going ahead to step 1:
7 divided by 730 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 730

On to step 2:
When dividing 78 by 730, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 730

Step 3:
730 can be fit into 785 1 times, resulting in a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 730 away from 785, we end up with 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 730

On to step 4:
558 divided by 730 is 0 with a remainder of 558.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 558, we get 558.
Take the next digit (0) from the dividend and append it to 558, then repeat: 5580 / 730

Moving on to step 5:
730 can be fit into 5580 7 times, resulting in a remainder of 470.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we take 5110 away from 5580, we end up with 470.
Bring next digit (2) of the dividend behind the 470 and repeat the process: 4702 / 730

Moving on to step 6:
The number 730 fits into 4702 6 times, leaving a remainder of 322.
Use 6 as the next digit of our solution. 
Result so far: 1076.0
If we take 4380 away from 4702, we end up with 322.
Grab the next digit (0) from the dividend, add it to 322, then carry on: 3220 / 730

Step 7:
730 can be fit into 3220 4 times, resulting in a remainder of 300.
Write down 4 as next digit of the result. 
Result so far: 10764.0
The remainder is 300 after subtracting 2920 from 3220.
Bring next digit (7) of the dividend behind the 300 and repeat the process: 3007 / 730

On to step 8:
730 can be fit into 3007 4 times, resulting in a remainder of 87.
Use 4 as the next digit of our solution. 
Result so far: 107644.0
Subtract 2920 from 3007 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 9:
The number 730 fits into 870 1 times, leaving a remainder of 140.
Use 1 as the next digit of our solution. 
Result so far: 107644.1
If we subtract 730 from 870, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
The number 730 fits into 1400 1 times, leaving a remainder of 670.
Use 1 as the next digit of our solution. 
Result so far: 107644.11
Subtract 730 from 1400 to 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.

The quotient of the division is 107644.11, and the remainder is 0.67.
