18078854 ÷ 485 
Our goal is to divide 18078854 by 485.

Advancing to step 1:
1 divided by 485 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 485

Advancing to step 2:
485 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 485

Advancing to step 3:
If we divide 180 by 485, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 180, we get 180.
Take the next digit (7) from the dividend and append it to 180, then repeat: 1807 / 485

Advancing to step 4:
485 goes into 1807 3 times with a remainder of 352.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 1455 away from 1807, we end up with 352.
Bring next digit (8) of the dividend behind the 352 and repeat the process: 3528 / 485

Advancing to step 5:
If we divide 3528 by 485, we get 7 and a remainder of 133.
The next digit of our result is 7. 
Result so far: 37.0
If we take 3395 away from 3528, we end up with 133.
Bring next digit (8) of the dividend behind the 133 and repeat the process: 1338 / 485

On to step 6:
The number 485 fits into 1338 2 times, leaving a remainder of 368.
Write down 2 as next digit of the result. 
Result so far: 372.0
Deduct 970 from 1338 and we're left with 368.
Append the next digit (5) from the dividend to 368 and continue with: 3685 / 485

Moving on to step 7:
485 can be fit into 3685 7 times, resulting in a remainder of 290.
The number 7 becomes the next digit in our result. 
Result so far: 3727.0
Subtracting 3395 from 3685 leaves us with 290.
Take the next digit (4) from the dividend and append it to 290, then repeat: 2904 / 485

Moving on to step 8:
485 can be fit into 2904 5 times, resulting in a remainder of 479.
Use 5 as the next digit of our solution. 
Result so far: 37275.0
If we take 2425 away from 2904, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Advancing to step 9:
The number 485 fits into 4790 9 times, leaving a remainder of 425.
The next digit of our result is 9. 
Result so far: 37275.9
Subtract 4365 from 4790 to 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.

Step 10:
When dividing 4250 by 485, we get 8 with a remainder of 370.
Put 8 as the next digit of the answer. 
Result so far: 37275.98
If we take 3880 away from 4250, we end up with 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 11:
When dividing 3700 by 485, we get 7 with a remainder of 305.
Record the quotient 7 as the next digit in the result. 
Result so far: 37275.987
If we take 3395 away from 3700, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 12:
If we divide 3050 by 485, we get 6 and a remainder of 140.
Write down 6 as next digit of the result. 
Result so far: 37275.9876
If we subtract 2910 from 3050, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 13:
If we divide 1400 by 485, we get 2 and a remainder of 430.
Record the quotient 2 as the next digit in the result. 
Result so far: 37275.98762
If we take 970 away from 1400, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 14:
4300 divided by 485 is 8 with a remainder of 420.
Write down 8 as next digit of the result. 
Result so far: 37275.987628
If we subtract 3880 from 4300, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 15:
485 can be fit into 4200 8 times, resulting in a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 37275.9876288
Deduct 3880 from 4200 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 37275.9876288 with a remainder of 3.2e-06.
