We look at the division of 72054783 by 345 
We're looking to find how many times 345 goes into 72054783.

Step 1:
The number 345 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 345

On to step 2:
If we divide 72 by 345, we get 0 and a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 345

Advancing to step 3:
345 can be fit into 720 2 times, resulting in a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 690 from 720, we get 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 345

Let's proceed to step 4:
345 goes into 305 0 times with a remainder of 305.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 305, we get 305.
Bring next digit (4) of the dividend behind the 305 and repeat the process: 3054 / 345

Going ahead to step 5:
If we divide 3054 by 345, we get 8 and a remainder of 294.
The number 8 becomes the next digit in our result. 
Result so far: 208.0
Deduct 2760 from 3054 and we're left with 294.
Bring next digit (7) of the dividend behind the 294 and repeat the process: 2947 / 345

On to step 6:
When dividing 2947 by 345, we get 8 with a remainder of 187.
The next digit of our result is 8. 
Result so far: 2088.0
Deduct 2760 from 2947 and we're left with 187.
Fetch the next digit (8) from the dividend, attach it to 187 and continue: 1878 / 345

Going ahead to step 7:
The number 345 fits into 1878 5 times, leaving a remainder of 153.
The number 5 becomes the next digit in our result. 
Result so far: 20885.0
If we take 1725 away from 1878, we end up with 153.
Bring next digit (3) of the dividend behind the 153 and repeat the process: 1533 / 345

Moving on to step 8:
345 goes into 1533 4 times with a remainder of 153.
Put 4 as the next digit of the answer. 
Result so far: 208854.0
Deduct 1380 from 1533 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 9:
345 can be fit into 1530 4 times, resulting in a remainder of 150.
The next digit of our result is 4. 
Result so far: 208854.4
Deduct 1380 from 1530 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 10:
345 goes into 1500 4 times with a remainder of 120.
The next digit of our result is 4. 
Result so far: 208854.44
Subtracting 1380 from 1500 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 208854.44 and a remainder of 0.12.
