Let's divide 81795757 by 505
Our goal is to divide 81795757 by 505.

Step 1:
505 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 505

Moving on to step 2:
If we divide 81 by 505, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 505

Step 3:
505 can be fit into 817 1 times, resulting in a remainder of 312.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 505 from 817 leaves us with 312.
Include the next digit (9) from the dividend after 312, then repeat: 3129 / 505

Let's proceed to step 4:
The number 505 fits into 3129 6 times, leaving a remainder of 99.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 3030 from 3129, we get 99.
Fetch the next digit (5) from the dividend, attach it to 99 and continue: 995 / 505

On to step 5:
The number 505 fits into 995 1 times, leaving a remainder of 490.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
If we take 505 away from 995, we end up with 490.
Include the next digit (7) from the dividend after 490, then repeat: 4907 / 505

Going ahead to step 6:
The number 505 fits into 4907 9 times, leaving a remainder of 362.
The next digit of our result is 9. 
Result so far: 1619.0
Subtract 4545 from 4907 to get 362.
Append the next digit (5) from the dividend to 362 and continue with: 3625 / 505

Step 7:
When dividing 3625 by 505, we get 7 with a remainder of 90.
Use 7 as the next digit of our solution. 
Result so far: 16197.0
Deduct 3535 from 3625 and we're left with 90.
Append the next digit (7) from the dividend to 90 and continue with: 907 / 505

Step 8:
907 divided by 505 is 1 with a remainder of 402.
Write down 1 as next digit of the result. 
Result so far: 161971.0
If we take 505 away from 907, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 9:
If we divide 4020 by 505, we get 7 and a remainder of 485.
Put 7 as the next digit of the answer. 
Result so far: 161971.7
If we take 3535 away from 4020, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Moving on to step 10:
If we divide 4850 by 505, we get 9 and a remainder of 305.
Write down 9 as next digit of the result. 
Result so far: 161971.79
If we take 4545 away from 4850, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 11:
505 can be fit into 3050 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 161971.796
The remainder is 20 after subtracting 3030 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
When dividing 200 by 505, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 161971.796
Subtracting 0 from 200 leaves us with 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 13:
If we divide 2000 by 505, we get 3 and a remainder of 485.
Record the quotient 3 as the next digit in the result. 
Result so far: 161971.79603
If we take 1515 away from 2000, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Going ahead to step 14:
If we divide 4850 by 505, we get 9 and a remainder of 305.
The next digit of our result is 9. 
Result so far: 161971.796039
If we take 4545 away from 4850, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 15:
The number 505 fits into 3050 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 161971.7960396
If we subtract 3030 from 3050, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 16:
If we divide 200 by 505, we get 0 and a remainder of 200.
The next digit of our result is 0. 
Result so far: 161971.7960396
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 161971.7960396, with a leftover of 2e-07.
