620525 ÷ 78 
Let's see how many times 78 fits into 620525.

On to step 1:
If we divide 6 by 78, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 78

Going ahead to step 2:
62 divided by 78 is 0 with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 78

On to step 3:
78 goes into 620 7 times with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 546 away from 620, we end up with 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 78

Step 4:
745 divided by 78 is 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Deduct 702 from 745 and we're left with 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 78

Step 5:
The number 78 fits into 432 5 times, leaving a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 795.0
Subtracting 390 from 432 leaves us with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 78

On to step 6:
78 can be fit into 425 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 7955.0
The remainder is 35 after subtracting 390 from 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
When dividing 350 by 78, we get 4 with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 7955.4
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
78 goes into 380 4 times with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 7955.44
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 7955.44 and a remainder of 0.068.
