4449215 ÷ 485 
We want to figure out the number of times 4449215 can be divided by 485.

On to step 1:
485 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 485

Step 2:
The number 485 fits into 44 0 times, leaving a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Fetch the next digit (4) from the dividend, attach it to 44 and continue: 444 / 485

Step 3:
If we divide 444 by 485, we get 0 and a remainder of 444.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 444 after subtracting 0 from 444.
Fetch the next digit (9) from the dividend, attach it to 444 and continue: 4449 / 485

Going ahead to step 4:
The number 485 fits into 4449 9 times, leaving a remainder of 84.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 84 after subtracting 4365 from 4449.
Fetch the next digit (2) from the dividend, attach it to 84 and continue: 842 / 485

Going ahead to step 5:
The number 485 fits into 842 1 times, leaving a remainder of 357.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtract 485 from 842 to get 357.
Grab the next digit (1) from the dividend, add it to 357, then carry on: 3571 / 485

Advancing to step 6:
3571 divided by 485 is 7 with a remainder of 176.
Put 7 as the next digit of the answer. 
Result so far: 917.0
Subtracting 3395 from 3571 leaves us with 176.
Bring next digit (5) of the dividend behind the 176 and repeat the process: 1765 / 485

Moving on to step 7:
If we divide 1765 by 485, we get 3 and a remainder of 310.
Put 3 as the next digit of the answer. 
Result so far: 9173.0
The remainder is 310 after subtracting 1455 from 1765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 8:
3100 divided by 485 is 6 with a remainder of 190.
Put 6 as the next digit of the answer. 
Result so far: 9173.6
The remainder is 190 after subtracting 2910 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 9:
If we divide 1900 by 485, we get 3 and a remainder of 445.
The number 3 becomes the next digit in our result. 
Result so far: 9173.63
The remainder is 445 after subtracting 1455 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 10:
If we divide 4450 by 485, we get 9 and a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 9173.639
If we take 4365 away from 4450, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 11:
When dividing 850 by 485, we get 1 with a remainder of 365.
Put 1 as the next digit of the answer. 
Result so far: 9173.6391
Deduct 485 from 850 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 12:
If we divide 3650 by 485, we get 7 and a remainder of 255.
The number 7 becomes the next digit in our result. 
Result so far: 9173.63917
If we take 3395 away from 3650, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 13:
If we divide 2550 by 485, we get 5 and a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 9173.639175
If we subtract 2425 from 2550, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 14:
485 goes into 1250 2 times with a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 9173.6391752
Deduct 970 from 1250 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 15:
485 goes into 2800 5 times with a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 9173.63917525
If we subtract 2425 from 2800, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

In conclusion, the division gives 9173.63917525 with a balance of 3.75e-07.
