We look at the division of 780390 by 97 
We want to divide 780390 by 97.

Advancing to step 1:
97 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 97

On to step 2:
97 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 97

Step 3:
97 goes into 780 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 776 from 780, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 97

Going ahead to step 4:
If we divide 43 by 97, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtract 0 from 43 to get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 97

Step 5:
97 can be fit into 439 4 times, resulting in a remainder of 51.
The number 4 becomes the next digit in our result. 
Result so far: 804.0
If we take 388 away from 439, we end up with 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 97

Advancing to step 6:
97 goes into 510 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 8045.0
Subtract 485 from 510 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
250 divided by 97 is 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 8045.2
Deduct 194 from 250 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 8:
97 can be fit into 560 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 8045.25
Deduct 485 from 560 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
97 can be fit into 750 7 times, resulting in a remainder of 71.
The next digit of our result is 7. 
Result so far: 8045.257
Subtracting 679 from 750 leaves us 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.

Advancing to step 10:
When dividing 710 by 97, we get 7 with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 8045.2577
If we take 679 away from 710, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 8045.2577 with a remaining 0.00031.
