We divide 57405798 by 305
We want to figure out the number of times 57405798 can be divided by 305.

Step 1:
When dividing 5 by 305, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 305

Step 2:
57 divided by 305 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Append the next digit (4) from the dividend to 57 and continue with: 574 / 305

Moving on to step 3:
305 can be fit into 574 1 times, resulting in a remainder of 269.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 305 away from 574, we end up with 269.
Grab the next digit (0) from the dividend, add it to 269, then carry on: 2690 / 305

Advancing to step 4:
When dividing 2690 by 305, we get 8 with a remainder of 250.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 250 after subtracting 2440 from 2690.
Grab the next digit (5) from the dividend, add it to 250, then carry on: 2505 / 305

Moving on to step 5:
The number 305 fits into 2505 8 times, leaving a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
If we take 2440 away from 2505, we end up with 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 305

Moving on to step 6:
When dividing 657 by 305, we get 2 with a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 1882.0
If we subtract 610 from 657, we get 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 305

Moving on to step 7:
479 divided by 305 is 1 with a remainder of 174.
The next digit of our result is 1. 
Result so far: 18821.0
If we take 305 away from 479, we end up with 174.
Include the next digit (8) from the dividend after 174, then repeat: 1748 / 305

Let's proceed to step 8:
305 goes into 1748 5 times with a remainder of 223.
Write down 5 as next digit of the result. 
Result so far: 188215.0
If we take 1525 away from 1748, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 9:
305 goes into 2230 7 times with a remainder of 95.
Write down 7 as next digit of the result. 
Result so far: 188215.7
Deduct 2135 from 2230 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 10:
305 goes into 950 3 times with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 188215.73
Subtract 915 from 950 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
305 goes into 350 1 times with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 188215.731
If we subtract 305 from 350, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
450 divided by 305 is 1 with a remainder of 145.
The next digit of our result is 1. 
Result so far: 188215.7311
If we take 305 away from 450, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

After the division, we end up with 188215.7311 and a remainder of 0.00145.
