198345 ÷ 1 
Let's see how many times 1 fits into 198345.

Step 1:
1 divided by 1 is 1 with 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 1 from 1.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Step 2:
9 divided by 1 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Moving on to step 3:
1 goes into 8 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 198.0
If we subtract 8 from 8, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Step 4:
3 divided by 1 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 1983.0
Deduct 3 from 3 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Advancing to step 5:
4 divided by 1 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 19834.0
The remainder is 0 after subtracting 4 from 4.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Step 6:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 198345.0
Subtract 5 from 5 to 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.

Moving on to step 7:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 198345.0
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.

Step 8:
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: 198345.0
Subtract 0 from 0 to 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 198345.0 with a remainder of 0.0.
