We look at the division of 339471 by 1 
We want to figure out the number of times 339471 can be divided by 1.

Let's proceed to step 1:
If we divide 3 by 1, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 3 from 3 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Moving on to step 2:
The number 1 fits into 3 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Moving on to step 3:
9 divided by 1 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 339.0
Deduct 9 from 9 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

On to step 4:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 3394.0
If we subtract 4 from 4, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

On to step 5:
1 goes into 7 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 33947.0
Subtracting 7 from 7 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Let's proceed to step 6:
If we divide 1 by 1, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 339471.0
If we take 1 away from 1, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 339471.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 339471.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 339471.0 with a remainder of 0.0.
