We're dividing 78084809 by 485 
Our goal is to divide 78084809 by 485.

Going ahead to step 1:
485 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 485

Advancing to step 2:
If we divide 78 by 485, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 485

On to step 3:
485 goes into 780 1 times with a remainder of 295.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 485 from 780 to get 295.
Grab the next digit (8) from the dividend, add it to 295, then carry on: 2958 / 485

Moving on to step 4:
When dividing 2958 by 485, we get 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 48 after subtracting 2910 from 2958.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 485

On to step 5:
485 can be fit into 484 0 times, resulting in a remainder of 484.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
The remainder is 484 after subtracting 0 from 484.
Include the next digit (8) from the dividend after 484, then repeat: 4848 / 485

Moving on to step 6:
4848 divided by 485 is 9 with a remainder of 483.
The next digit of our result is 9. 
Result so far: 1609.0
Subtracting 4365 from 4848 leaves us with 483.
Fetch the next digit (0) from the dividend, attach it to 483 and continue: 4830 / 485

Step 7:
The number 485 fits into 4830 9 times, leaving a remainder of 465.
The number 9 becomes the next digit in our result. 
Result so far: 16099.0
Subtract 4365 from 4830 to get 465.
Fetch the next digit (9) from the dividend, attach it to 465 and continue: 4659 / 485

Moving on to step 8:
If we divide 4659 by 485, we get 9 and a remainder of 294.
The number 9 becomes the next digit in our result. 
Result so far: 160999.0
Deduct 4365 from 4659 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 9:
The number 485 fits into 2940 6 times, leaving a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 160999.6
The remainder is 30 after subtracting 2910 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
300 divided by 485 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 160999.6
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
When dividing 3000 by 485, we get 6 with a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 160999.606
Subtracting 2910 from 3000 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
900 divided by 485 is 1 with a remainder of 415.
The next digit of our result is 1. 
Result so far: 160999.6061
Deduct 485 from 900 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Going ahead to step 13:
485 can be fit into 4150 8 times, resulting in a remainder of 270.
The number 8 becomes the next digit in our result. 
Result so far: 160999.60618
Subtracting 3880 from 4150 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 14:
If we divide 2700 by 485, we get 5 and a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 160999.606185
The remainder is 275 after subtracting 2425 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 15:
485 goes into 2750 5 times with a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 160999.6061855
If we take 2425 away from 2750, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

The final outcome is 160999.6061855, with a leftover of 3.25e-06.
