We're dividing 17720137 by 305 
Our goal is to divide 17720137 by 305.

Step 1:
The number 305 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 305

On to step 2:
The number 305 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 305

Advancing to step 3:
When dividing 177 by 305, we get 0 with a remainder of 177.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 177 leaves us with 177.
Take the next digit (2) from the dividend and append it to 177, then repeat: 1772 / 305

Advancing to step 4:
305 can be fit into 1772 5 times, resulting in a remainder of 247.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 1525 away from 1772, we end up with 247.
Include the next digit (0) from the dividend after 247, then repeat: 2470 / 305

On to step 5:
2470 divided by 305 is 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtracting 2440 from 2470 leaves us with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 305

Advancing to step 6:
305 can be fit into 301 0 times, resulting in a remainder of 301.
The next digit of our result is 0. 
Result so far: 580.0
Subtracting 0 from 301 leaves us with 301.
Append the next digit (3) from the dividend to 301 and continue with: 3013 / 305

Moving on to step 7:
When dividing 3013 by 305, we get 9 with a remainder of 268.
Put 9 as the next digit of the answer. 
Result so far: 5809.0
Subtract 2745 from 3013 to get 268.
Include the next digit (7) from the dividend after 268, then repeat: 2687 / 305

Advancing to step 8:
305 goes into 2687 8 times with a remainder of 247.
Put 8 as the next digit of the answer. 
Result so far: 58098.0
If we take 2440 away from 2687, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 9:
The number 305 fits into 2470 8 times, leaving a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 58098.8
Subtract 2440 from 2470 to get 30.
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 10:
The number 305 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 58098.8
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
When dividing 3000 by 305, we get 9 with a remainder of 255.
Put 9 as the next digit of the answer. 
Result so far: 58098.809
Deduct 2745 from 3000 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 12:
When dividing 2550 by 305, we get 8 with a remainder of 110.
The next digit of our result is 8. 
Result so far: 58098.8098
Deduct 2440 from 2550 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 13:
If we divide 1100 by 305, we get 3 and a remainder of 185.
The number 3 becomes the next digit in our result. 
Result so far: 58098.80983
The remainder is 185 after subtracting 915 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 14:
If we divide 1850 by 305, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 58098.809836
Deduct 1830 from 1850 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
If we divide 200 by 305, we get 0 and a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 58098.809836
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 16:
When dividing 2000 by 305, we get 6 with a remainder of 170.
Record the quotient 6 as the next digit in the result. 
Result so far: 58098.80983606
The remainder is 170 after subtracting 1830 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 58098.80983606 with a balance of 1.7e-07.
