We divide 356340 by 1
We're looking to find how many times 1 goes into 356340.

Advancing to step 1:
If we divide 3 by 1, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 3 from 3, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Moving on to step 2:
The number 1 fits into 5 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 5 from 5 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

On to step 3:
If we divide 6 by 1, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 356.0
Subtract 6 from 6 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Moving on to step 4:
When dividing 3 by 1, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3563.0
Subtract 3 from 3 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

On to step 5:
4 divided by 1 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 35634.0
Subtract 4 from 4 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Let's proceed to step 6:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 356340.0
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.

Advancing to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 356340.0
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.

Advancing to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 356340.0
The remainder is 0 after subtracting 0 from 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 outcome is 356340.0, with a leftover of 0.0.
