Let's divide 342093 by 45
We want to figure out the number of times 342093 can be divided by 45.

Step 1:
45 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 45

On to step 2:
When dividing 34 by 45, we get 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 45

On to step 3:
45 can be fit into 342 7 times, resulting in a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 315 away from 342, we end up with 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 45

Advancing to step 4:
45 can be fit into 270 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 270 from 270, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 45

Going ahead to step 5:
The number 45 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 760.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 45

Moving on to step 6:
45 can be fit into 93 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 7602.0
If we subtract 90 from 93, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 45 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 7602.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
When dividing 300 by 45, we get 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 7602.06
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
300 divided by 45 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 7602.066
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 7602.066 with a remainder of 0.003.
