339768 divided by 45 
We want to figure out the number of times 339768 can be divided by 45.

Step 1:
45 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 45

Advancing to step 2:
If we divide 33 by 45, we get 0 and a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 45

On to step 3:
339 divided by 45 is 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 315 away from 339, we end up with 24.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 45

Going ahead to step 4:
247 divided by 45 is 5 with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we take 225 away from 247, we end up with 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 45

On to step 5:
If we divide 226 by 45, we get 5 and a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 755.0
Subtracting 225 from 226 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 45

Advancing to step 6:
18 divided by 45 is 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 7550.0
If we subtract 0 from 18, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
45 can be fit into 180 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 7550.4
If we subtract 180 from 180, 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.

Going ahead to step 8:
When dividing 0 by 45, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7550.4
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.

Step 9:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7550.4
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.

In conclusion, the division gives 7550.4 with a balance of 0.0.
