We divide 339474 by 1
We're looking to find how many times 1 goes into 339474.

Moving on to step 1:
When dividing 3 by 1, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 3 from 3 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Moving on to step 2:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 3 away from 3, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Step 3:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 339.0
The remainder is 0 after subtracting 9 from 9.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Advancing to step 4:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 3394.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Moving on to step 5:
1 goes into 7 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 33947.0
If we subtract 7 from 7, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Step 6:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 339474.0
Deduct 4 from 4 and we're left 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.

Moving on to step 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 339474.0
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.

Let's proceed to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 339474.0
Deduct 0 from 0 and we're left 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.

After the division, we end up with 339474.0 and a remainder of 0.0.
