We look at the division of 398510 by 73 
Our goal is to divide 398510 by 73.

Advancing to step 1:
If we divide 3 by 73, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 73

On to step 2:
39 divided by 73 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 73

Advancing to step 3:
73 goes into 398 5 times with a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 365 from 398, we get 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 73

Going ahead to step 4:
73 goes into 335 4 times with a remainder of 43.
The next digit of our result is 4. 
Result so far: 54.0
Subtract 292 from 335 to get 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 73

Let's proceed to step 5:
The number 73 fits into 431 5 times, leaving a remainder of 66.
Record the quotient 5 as the next digit in the result. 
Result so far: 545.0
Subtracting 365 from 431 leaves us with 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 73

Going ahead to step 6:
If we divide 660 by 73, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 5459.0
Subtract 657 from 660 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 73 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 5459.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
If we divide 300 by 73, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 5459.04
The remainder is 8 after subtracting 292 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
73 goes into 80 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 5459.041
Subtract 73 from 80 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.

Moving on to step 10:
When dividing 70 by 73, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 5459.041
Subtracting 0 from 70 leaves us 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.

Moving on to step 11:
73 can be fit into 700 9 times, resulting in a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 5459.04109
If we take 657 away from 700, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 12:
73 goes into 430 5 times with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 5459.041095
Subtracting 365 from 430 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 13:
The number 73 fits into 650 8 times, leaving a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 5459.0410958
If we take 584 away from 650, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 14:
The number 73 fits into 660 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 5459.04109589
The remainder is 3 after subtracting 657 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 5459.04109589 and a remainder of 3e-09.
