Let's divide 398759 by 3
We want to figure out the number of times 398759 can be divided by 3.

Moving on to step 1:
3 can be fit into 3 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 3 from 3.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 3

Advancing to step 2:
When dividing 9 by 3, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 9 from 9 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Moving on to step 3:
3 goes into 8 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
If we subtract 6 from 8, we get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

Let's proceed to step 4:
3 goes into 27 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 1329.0
If we subtract 27 from 27, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 3

Let's proceed to step 5:
If we divide 5 by 3, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 13291.0
Subtracting 3 from 5 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 3

Let's proceed to step 6:
If we divide 29 by 3, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 132919.0
Deduct 27 from 29 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
20 divided by 3 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 132919.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
3 goes into 20 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 132919.66
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 132919.66 with a remainder of 0.002.
