We're dividing 18578392 by 485 
Let's see how many times 485 fits into 18578392.

Going ahead to step 1:
485 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 485

On to step 2:
485 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 485

Let's proceed to step 3:
185 divided by 485 is 0 with a remainder of 185.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 185, we end up with 185.
Take the next digit (7) from the dividend and append it to 185, then repeat: 1857 / 485

Moving on to step 4:
485 goes into 1857 3 times with a remainder of 402.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1455 away from 1857, we end up with 402.
Grab the next digit (8) from the dividend, add it to 402, then carry on: 4028 / 485

Let's proceed to step 5:
When dividing 4028 by 485, we get 8 with a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 3880 away from 4028, we end up with 148.
Include the next digit (3) from the dividend after 148, then repeat: 1483 / 485

Going ahead to step 6:
1483 divided by 485 is 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 383.0
Subtracting 1455 from 1483 leaves us with 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 485

Going ahead to step 7:
If we divide 289 by 485, we get 0 and a remainder of 289.
Put 0 as the next digit of the answer. 
Result so far: 3830.0
If we take 0 away from 289, we end up with 289.
Append the next digit (2) from the dividend to 289 and continue with: 2892 / 485

Going ahead to step 8:
The number 485 fits into 2892 5 times, leaving a remainder of 467.
Put 5 as the next digit of the answer. 
Result so far: 38305.0
If we take 2425 away from 2892, we end up with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Step 9:
485 goes into 4670 9 times with a remainder of 305.
Write down 9 as next digit of the result. 
Result so far: 38305.9
If we take 4365 away from 4670, 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 10:
If we divide 3050 by 485, we get 6 and a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 38305.96
Subtracting 2910 from 3050 leaves us 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.

Step 11:
1400 divided by 485 is 2 with a remainder of 430.
The next digit of our result is 2. 
Result so far: 38305.962
Deduct 970 from 1400 and we're left 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.

On to step 12:
If we divide 4300 by 485, we get 8 and a remainder of 420.
Record the quotient 8 as the next digit in the result. 
Result so far: 38305.9628
Subtract 3880 from 4300 to 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.

On to step 13:
485 goes into 4200 8 times with a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 38305.96288
If we subtract 3880 from 4200, we get 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 outcome is 38305.96288, with a leftover of 0.00032.
