We look at the division of 8910015 by 485 
We want to figure out the number of times 8910015 can be divided by 485.

Moving on to step 1:
The number 485 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 485

Going ahead to step 2:
89 divided by 485 is 0 with a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Take the next digit (1) from the dividend and append it to 89, then repeat: 891 / 485

On to step 3:
The number 485 fits into 891 1 times, leaving a remainder of 406.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 485 from 891, we get 406.
Include the next digit (0) from the dividend after 406, then repeat: 4060 / 485

Moving on to step 4:
4060 divided by 485 is 8 with a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 3880 from 4060 leaves us with 180.
Include the next digit (0) from the dividend after 180, then repeat: 1800 / 485

Advancing to step 5:
485 goes into 1800 3 times with a remainder of 345.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
If we take 1455 away from 1800, we end up with 345.
Grab the next digit (1) from the dividend, add it to 345, then carry on: 3451 / 485

On to step 6:
If we divide 3451 by 485, we get 7 and a remainder of 56.
The next digit of our result is 7. 
Result so far: 1837.0
The remainder is 56 after subtracting 3395 from 3451.
Fetch the next digit (5) from the dividend, attach it to 56 and continue: 565 / 485

Going ahead to step 7:
When dividing 565 by 485, we get 1 with a remainder of 80.
Write down 1 as next digit of the result. 
Result so far: 18371.0
The remainder is 80 after subtracting 485 from 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
The number 485 fits into 800 1 times, leaving a remainder of 315.
The number 1 becomes the next digit in our result. 
Result so far: 18371.1
If we subtract 485 from 800, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 9:
485 can be fit into 3150 6 times, resulting in a remainder of 240.
Put 6 as the next digit of the answer. 
Result so far: 18371.16
Subtracting 2910 from 3150 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
The number 485 fits into 2400 4 times, leaving a remainder of 460.
The next digit of our result is 4. 
Result so far: 18371.164
Deduct 1940 from 2400 and we're left with 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:
485 goes into 4600 9 times with a remainder of 235.
Put 9 as the next digit of the answer. 
Result so far: 18371.1649
Deduct 4365 from 4600 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 12:
When dividing 2350 by 485, we get 4 with a remainder of 410.
Use 4 as the next digit of our solution. 
Result so far: 18371.16494
The remainder is 410 after subtracting 1940 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 13:
485 can be fit into 4100 8 times, resulting in a remainder of 220.
Record the quotient 8 as the next digit in the result. 
Result so far: 18371.164948
The remainder is 220 after subtracting 3880 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 14:
485 can be fit into 2200 4 times, resulting in a remainder of 260.
The next digit of our result is 4. 
Result so far: 18371.1649484
If we take 1940 away from 2200, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 15:
485 goes into 2600 5 times with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 18371.16494845
The remainder is 175 after subtracting 2425 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final result is 18371.16494845 with a remainder of 1.75e-07.
