77803914 ÷ 485 
Our goal is to divide 77803914 by 485.

Advancing to step 1:
The number 485 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 485

Let's proceed to step 2:
When dividing 77 by 485, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 485

Moving on to step 3:
778 divided by 485 is 1 with a remainder of 293.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 485 away from 778, we end up with 293.
Grab the next digit (0) from the dividend, add it to 293, then carry on: 2930 / 485

Let's proceed to step 4:
If we divide 2930 by 485, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 2910 from 2930 leaves us with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 485

Let's proceed to step 5:
485 can be fit into 203 0 times, resulting in a remainder of 203.
Put 0 as the next digit of the answer. 
Result so far: 160.0
The remainder is 203 after subtracting 0 from 203.
Include the next digit (9) from the dividend after 203, then repeat: 2039 / 485

Step 6:
2039 divided by 485 is 4 with a remainder of 99.
Use 4 as the next digit of our solution. 
Result so far: 1604.0
Subtracting 1940 from 2039 leaves us with 99.
Bring next digit (1) of the dividend behind the 99 and repeat the process: 991 / 485

On to step 7:
485 can be fit into 991 2 times, resulting in a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 16042.0
If we take 970 away from 991, we end up with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 485

Let's proceed to step 8:
485 goes into 214 0 times with a remainder of 214.
The next digit of our result is 0. 
Result so far: 160420.0
Deduct 0 from 214 and we're left 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.

Moving on to step 9:
485 can be fit into 2140 4 times, resulting in a remainder of 200.
Write down 4 as next digit of the result. 
Result so far: 160420.4
If we take 1940 away from 2140, we end up 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 10:
When dividing 2000 by 485, we get 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 160420.44
Subtract 1940 from 2000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 160420.44 with a remaining 0.06.
