45845408 ÷ 203 
We want to figure out the number of times 45845408 can be divided by 203.

On to step 1:
The number 203 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 203

Let's proceed to step 2:
The number 203 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 203

Let's proceed to step 3:
If we divide 458 by 203, we get 2 and a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 52 after subtracting 406 from 458.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 203

Going ahead to step 4:
If we divide 524 by 203, we get 2 and a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 406 from 524 and we're left with 118.
Include the next digit (5) from the dividend after 118, then repeat: 1185 / 203

Let's proceed to step 5:
1185 divided by 203 is 5 with a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 225.0
Subtract 1015 from 1185 to get 170.
Take the next digit (4) from the dividend and append it to 170, then repeat: 1704 / 203

Going ahead to step 6:
203 goes into 1704 8 times with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 2258.0
The remainder is 80 after subtracting 1624 from 1704.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 203

Let's proceed to step 7:
The number 203 fits into 800 3 times, leaving a remainder of 191.
Use 3 as the next digit of our solution. 
Result so far: 22583.0
Subtract 609 from 800 to get 191.
Grab the next digit (8) from the dividend, add it to 191, then carry on: 1918 / 203

Let's proceed to step 8:
If we divide 1918 by 203, we get 9 and a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 225839.0
Deduct 1827 from 1918 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 9:
203 can be fit into 910 4 times, resulting in a remainder of 98.
The number 4 becomes the next digit in our result. 
Result so far: 225839.4
If we take 812 away from 910, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
When dividing 980 by 203, we get 4 with a remainder of 168.
Use 4 as the next digit of our solution. 
Result so far: 225839.44
If we subtract 812 from 980, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

In conclusion, the division gives 225839.44 with a balance of 0.168.
