We divide 77890841 by 505
We want to divide 77890841 by 505.

Let's proceed to step 1:
7 divided by 505 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 505

Advancing to step 2:
If we divide 77 by 505, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 505

Let's proceed to step 3:
505 goes into 778 1 times with a remainder of 273.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 505 from 778, we get 273.
Fetch the next digit (9) from the dividend, attach it to 273 and continue: 2739 / 505

Going ahead to step 4:
2739 divided by 505 is 5 with a remainder of 214.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2525 from 2739 and we're left with 214.
Bring next digit (0) of the dividend behind the 214 and repeat the process: 2140 / 505

Step 5:
When dividing 2140 by 505, we get 4 with a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 154.0
Deduct 2020 from 2140 and we're left with 120.
Append the next digit (8) from the dividend to 120 and continue with: 1208 / 505

On to step 6:
If we divide 1208 by 505, we get 2 and a remainder of 198.
The next digit of our result is 2. 
Result so far: 1542.0
If we subtract 1010 from 1208, we get 198.
Grab the next digit (4) from the dividend, add it to 198, then carry on: 1984 / 505

Advancing to step 7:
When dividing 1984 by 505, we get 3 with a remainder of 469.
Put 3 as the next digit of the answer. 
Result so far: 15423.0
Subtract 1515 from 1984 to get 469.
Take the next digit (1) from the dividend and append it to 469, then repeat: 4691 / 505

Advancing to step 8:
505 can be fit into 4691 9 times, resulting in a remainder of 146.
Record the quotient 9 as the next digit in the result. 
Result so far: 154239.0
Subtract 4545 from 4691 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 9:
If we divide 1460 by 505, we get 2 and a remainder of 450.
Use 2 as the next digit of our solution. 
Result so far: 154239.2
Subtract 1010 from 1460 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 10:
505 goes into 4500 8 times with a remainder of 460.
Put 8 as the next digit of the answer. 
Result so far: 154239.28
Subtract 4040 from 4500 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
The number 505 fits into 4600 9 times, leaving a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 154239.289
If we subtract 4545 from 4600, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 12:
If we divide 550 by 505, we get 1 and a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 154239.2891
Subtract 505 from 550 to 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.

Moving on to step 13:
The number 505 fits into 450 0 times, leaving a remainder of 450.
The next digit of our result is 0. 
Result so far: 154239.2891
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 14:
The number 505 fits into 4500 8 times, leaving a remainder of 460.
Put 8 as the next digit of the answer. 
Result so far: 154239.289108
If we subtract 4040 from 4500, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 15:
4600 divided by 505 is 9 with a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 154239.2891089
Subtracting 4545 from 4600 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 16:
The number 505 fits into 550 1 times, leaving a remainder of 45.
The next digit of our result is 1. 
Result so far: 154239.28910891
Deduct 505 from 550 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 154239.28910891 with a remainder of 4.5e-08.
