We're dividing 8486830 by 203 
We want to figure out the number of times 8486830 can be divided by 203.

Step 1:
If we divide 8 by 203, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 203

Advancing to step 2:
203 can be fit into 84 0 times, resulting in a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Take the next digit (8) from the dividend and append it to 84, then repeat: 848 / 203

On to step 3:
203 goes into 848 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 36 after subtracting 812 from 848.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 203

Let's proceed to step 4:
203 goes into 366 1 times with a remainder of 163.
Write down 1 as next digit of the result. 
Result so far: 41.0
Deduct 203 from 366 and we're left with 163.
Append the next digit (8) from the dividend to 163 and continue with: 1638 / 203

Going ahead to step 5:
When dividing 1638 by 203, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 418.0
The remainder is 14 after subtracting 1624 from 1638.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 203

Going ahead to step 6:
The number 203 fits into 143 0 times, leaving a remainder of 143.
Put 0 as the next digit of the answer. 
Result so far: 4180.0
If we take 0 away from 143, we end up with 143.
Include the next digit (0) from the dividend after 143, then repeat: 1430 / 203

Step 7:
If we divide 1430 by 203, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 41807.0
Subtracting 1421 from 1430 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
The number 203 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 41807.0
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 9:
203 goes into 900 4 times with a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 41807.04
If we take 812 away from 900, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 10:
If we divide 880 by 203, we get 4 and a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 41807.044
The remainder is 68 after subtracting 812 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 41807.044, and the remainder is 0.0068.
