52290603 ÷ 305 
We want to figure out the number of times 52290603 can be divided by 305.

Advancing to step 1:
When dividing 5 by 305, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 305

Let's proceed to step 2:
The number 305 fits into 52 0 times, leaving a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 305

Step 3:
522 divided by 305 is 1 with a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 305 from 522 leaves us with 217.
Bring next digit (9) of the dividend behind the 217 and repeat the process: 2179 / 305

Going ahead to step 4:
If we divide 2179 by 305, we get 7 and a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 2135 from 2179 to get 44.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 305

On to step 5:
If we divide 440 by 305, we get 1 and a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 171.0
Deduct 305 from 440 and we're left with 135.
Bring next digit (6) of the dividend behind the 135 and repeat the process: 1356 / 305

Moving on to step 6:
The number 305 fits into 1356 4 times, leaving a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 1714.0
Deduct 1220 from 1356 and we're left with 136.
Take the next digit (0) from the dividend and append it to 136, then repeat: 1360 / 305

Going ahead to step 7:
1360 divided by 305 is 4 with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 17144.0
If we take 1220 away from 1360, we end up with 140.
Include the next digit (3) from the dividend after 140, then repeat: 1403 / 305

Advancing to step 8:
305 can be fit into 1403 4 times, resulting in a remainder of 183.
The next digit of our result is 4. 
Result so far: 171444.0
If we take 1220 away from 1403, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 9:
305 can be fit into 1830 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 171444.6
Subtract 1830 from 1830 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.

Let's proceed to step 10:
When dividing 0 by 305, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 171444.6
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 11:
0 divided by 305 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 171444.6
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.

In conclusion, the division gives 171444.6 with a balance of 0.0.
