We're dividing 398572 by 83 
We're looking to find how many times 83 goes into 398572.

Going ahead to step 1:
The number 83 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 83

On to step 2:
If we divide 39 by 83, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 83

Advancing to step 3:
398 divided by 83 is 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 332 from 398, we get 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 83

Step 4:
83 goes into 665 8 times with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 664 from 665 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 83

Going ahead to step 5:
83 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 480.0
Subtract 0 from 17 to get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 83

On to step 6:
If we divide 172 by 83, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 4802.0
Subtract 166 from 172 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
83 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 4802.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
83 can be fit into 600 7 times, resulting in a remainder of 19.
The next digit of our result is 7. 
Result so far: 4802.07
Subtracting 581 from 600 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
The number 83 fits into 190 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 4802.072
The remainder is 24 after subtracting 166 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
83 can be fit into 240 2 times, resulting in a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 4802.0722
The remainder is 74 after subtracting 166 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 4802.0722 and a remainder of 0.00074.
