We look at the division of 393439 by 97 
We're looking to find how many times 97 goes into 393439.

Moving on to step 1:
3 divided by 97 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 97

Step 2:
39 divided by 97 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 97

On to step 3:
The number 97 fits into 393 4 times, leaving a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 388 from 393 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 97

Moving on to step 4:
When dividing 54 by 97, we get 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we subtract 0 from 54, we get 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 97

Going ahead to step 5:
The number 97 fits into 543 5 times, leaving a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 405.0
Deduct 485 from 543 and we're left with 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 97

Step 6:
The number 97 fits into 589 6 times, leaving a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 4056.0
Subtract 582 from 589 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
When dividing 70 by 97, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 4056.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
The number 97 fits into 700 7 times, leaving a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 4056.07
Subtracting 679 from 700 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
When dividing 210 by 97, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 4056.072
If we take 194 away from 210, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
The number 97 fits into 160 1 times, leaving a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 4056.0721
Subtract 97 from 160 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 11:
If we divide 630 by 97, we get 6 and a remainder of 48.
The next digit of our result is 6. 
Result so far: 4056.07216
If we take 582 away from 630, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
97 can be fit into 480 4 times, resulting in a remainder of 92.
The number 4 becomes the next digit in our result. 
Result so far: 4056.072164
Deduct 388 from 480 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 13:
97 goes into 920 9 times with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 4056.0721649
Subtract 873 from 920 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 14:
The number 97 fits into 470 4 times, leaving a remainder of 82.
Write down 4 as next digit of the result. 
Result so far: 4056.07216494
Subtract 388 from 470 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

After the division, we end up with 4056.07216494 and a remainder of 8.2e-08.
