We're dividing 90771439 by 505 
We want to figure out the number of times 90771439 can be divided by 505.

Step 1:
505 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 505

On to step 2:
When dividing 90 by 505, we get 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Bring next digit (7) of the dividend behind the 90 and repeat the process: 907 / 505

On to step 3:
When dividing 907 by 505, we get 1 with a remainder of 402.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 505 from 907, we get 402.
Fetch the next digit (7) from the dividend, attach it to 402 and continue: 4027 / 505

Moving on to step 4:
If we divide 4027 by 505, we get 7 and a remainder of 492.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 3535 from 4027 and we're left with 492.
Append the next digit (1) from the dividend to 492 and continue with: 4921 / 505

On to step 5:
If we divide 4921 by 505, we get 9 and a remainder of 376.
Put 9 as the next digit of the answer. 
Result so far: 179.0
If we subtract 4545 from 4921, we get 376.
Fetch the next digit (4) from the dividend, attach it to 376 and continue: 3764 / 505

Going ahead to step 6:
When dividing 3764 by 505, we get 7 with a remainder of 229.
The number 7 becomes the next digit in our result. 
Result so far: 1797.0
The remainder is 229 after subtracting 3535 from 3764.
Bring next digit (3) of the dividend behind the 229 and repeat the process: 2293 / 505

Going ahead to step 7:
2293 divided by 505 is 4 with a remainder of 273.
Record the quotient 4 as the next digit in the result. 
Result so far: 17974.0
Subtracting 2020 from 2293 leaves us with 273.
Bring next digit (9) of the dividend behind the 273 and repeat the process: 2739 / 505

Moving on to step 8:
If we divide 2739 by 505, we get 5 and a remainder of 214.
Write down 5 as next digit of the result. 
Result so far: 179745.0
If we take 2525 away from 2739, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 9:
2140 divided by 505 is 4 with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 179745.4
Subtracting 2020 from 2140 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.

Going ahead to step 10:
When dividing 1200 by 505, we get 2 with a remainder of 190.
Put 2 as the next digit of the answer. 
Result so far: 179745.42
Subtracting 1010 from 1200 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
1900 divided by 505 is 3 with a remainder of 385.
The next digit of our result is 3. 
Result so far: 179745.423
The remainder is 385 after subtracting 1515 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 12:
505 can be fit into 3850 7 times, resulting in a remainder of 315.
Write down 7 as next digit of the result. 
Result so far: 179745.4237
The remainder is 315 after subtracting 3535 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 13:
When dividing 3150 by 505, we get 6 with a remainder of 120.
The next digit of our result is 6. 
Result so far: 179745.42376
If we subtract 3030 from 3150, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
The number 505 fits into 1200 2 times, leaving a remainder of 190.
The next digit of our result is 2. 
Result so far: 179745.423762
Subtract 1010 from 1200 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 15:
505 can be fit into 1900 3 times, resulting in a remainder of 385.
The number 3 becomes the next digit in our result. 
Result so far: 179745.4237623
Subtract 1515 from 1900 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 16:
The number 505 fits into 3850 7 times, leaving a remainder of 315.
The next digit of our result is 7. 
Result so far: 179745.42376237
Deduct 3535 from 3850 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

In conclusion, the division gives 179745.42376237 with a balance of 3.15e-07.
