We look at the division of 81603382 by 485 
We want to divide 81603382 by 485.

Let's proceed to step 1:
The number 485 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 485

On to step 2:
When dividing 81 by 485, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (6) of the dividend behind the 81 and repeat the process: 816 / 485

On to step 3:
When dividing 816 by 485, we get 1 with a remainder of 331.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 485 from 816 leaves us with 331.
Bring next digit (0) of the dividend behind the 331 and repeat the process: 3310 / 485

Going ahead to step 4:
The number 485 fits into 3310 6 times, leaving a remainder of 400.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 2910 from 3310 leaves us with 400.
Take the next digit (3) from the dividend and append it to 400, then repeat: 4003 / 485

Moving on to step 5:
If we divide 4003 by 485, we get 8 and a remainder of 123.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
Subtract 3880 from 4003 to get 123.
Bring next digit (3) of the dividend behind the 123 and repeat the process: 1233 / 485

Advancing to step 6:
If we divide 1233 by 485, we get 2 and a remainder of 263.
The next digit of our result is 2. 
Result so far: 1682.0
If we subtract 970 from 1233, we get 263.
Include the next digit (8) from the dividend after 263, then repeat: 2638 / 485

Going ahead to step 7:
485 can be fit into 2638 5 times, resulting in a remainder of 213.
The next digit of our result is 5. 
Result so far: 16825.0
Subtracting 2425 from 2638 leaves us with 213.
Include the next digit (2) from the dividend after 213, then repeat: 2132 / 485

Going ahead to step 8:
2132 divided by 485 is 4 with a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 168254.0
Subtract 1940 from 2132 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 9:
If we divide 1920 by 485, we get 3 and a remainder of 465.
Write down 3 as next digit of the result. 
Result so far: 168254.3
If we subtract 1455 from 1920, we get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Step 10:
When dividing 4650 by 485, we get 9 with a remainder of 285.
Write down 9 as next digit of the result. 
Result so far: 168254.39
The remainder is 285 after subtracting 4365 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 11:
485 goes into 2850 5 times with a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 168254.395
If we subtract 2425 from 2850, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 12:
When dividing 4250 by 485, we get 8 with a remainder of 370.
The number 8 becomes the next digit in our result. 
Result so far: 168254.3958
Subtract 3880 from 4250 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 13:
485 goes into 3700 7 times with a remainder of 305.
Put 7 as the next digit of the answer. 
Result so far: 168254.39587
Subtract 3395 from 3700 to get 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 14:
3050 divided by 485 is 6 with a remainder of 140.
The number 6 becomes the next digit in our result. 
Result so far: 168254.395876
Deduct 2910 from 3050 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 15:
The number 485 fits into 1400 2 times, leaving a remainder of 430.
Use 2 as the next digit of our solution. 
Result so far: 168254.3958762
If we subtract 970 from 1400, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 16:
If we divide 4300 by 485, we get 8 and a remainder of 420.
Write down 8 as next digit of the result. 
Result so far: 168254.39587628
The remainder is 420 after subtracting 3880 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Our division results in 168254.39587628 with a remaining 4.2e-07.
