84202257 ÷ 305 
We want to figure out the number of times 84202257 can be divided by 305.

Advancing to step 1:
The number 305 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 305

Let's proceed to step 2:
84 divided by 305 is 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Take the next digit (2) from the dividend and append it to 84, then repeat: 842 / 305

Advancing to step 3:
305 can be fit into 842 2 times, resulting in a remainder of 232.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 232 after subtracting 610 from 842.
Bring next digit (0) of the dividend behind the 232 and repeat the process: 2320 / 305

Step 4:
When dividing 2320 by 305, we get 7 with a remainder of 185.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 2135 from 2320 leaves us with 185.
Bring next digit (2) of the dividend behind the 185 and repeat the process: 1852 / 305

Advancing to step 5:
1852 divided by 305 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 276.0
The remainder is 22 after subtracting 1830 from 1852.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 305

Moving on to step 6:
222 divided by 305 is 0 with a remainder of 222.
Use 0 as the next digit of our solution. 
Result so far: 2760.0
If we subtract 0 from 222, we get 222.
Include the next digit (5) from the dividend after 222, then repeat: 2225 / 305

Step 7:
The number 305 fits into 2225 7 times, leaving a remainder of 90.
The next digit of our result is 7. 
Result so far: 27607.0
Subtract 2135 from 2225 to get 90.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 305

Going ahead to step 8:
The number 305 fits into 907 2 times, leaving a remainder of 297.
The number 2 becomes the next digit in our result. 
Result so far: 276072.0
Subtract 610 from 907 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 9:
When dividing 2970 by 305, we get 9 with a remainder of 225.
Write down 9 as next digit of the result. 
Result so far: 276072.9
Subtracting 2745 from 2970 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 10:
If we divide 2250 by 305, we get 7 and a remainder of 115.
Use 7 as the next digit of our solution. 
Result so far: 276072.97
Subtracting 2135 from 2250 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 11:
305 goes into 1150 3 times with a remainder of 235.
The number 3 becomes the next digit in our result. 
Result so far: 276072.973
Deduct 915 from 1150 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 12:
The number 305 fits into 2350 7 times, leaving a remainder of 215.
Write down 7 as next digit of the result. 
Result so far: 276072.9737
Subtracting 2135 from 2350 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 13:
When dividing 2150 by 305, we get 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 276072.97377
Subtracting 2135 from 2150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 276072.97377 with a remainder of 1.5e-05.
