450903 ÷ 68 
Our goal is to divide 450903 by 68.

On to step 1:
68 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 68

Moving on to step 2:
68 goes into 45 0 times with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 68

Advancing to step 3:
68 can be fit into 450 6 times, resulting in a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 408 from 450 and we're left with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 68

Moving on to step 4:
If we divide 429 by 68, we get 6 and a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we subtract 408 from 429, we get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 68

Advancing to step 5:
68 can be fit into 210 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 663.0
If we take 204 away from 210, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 68

Moving on to step 6:
When dividing 63 by 68, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 6630.0
Subtracting 0 from 63 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
68 can be fit into 630 9 times, resulting in a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 6630.9
If we subtract 612 from 630, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
180 divided by 68 is 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 6630.92
The remainder is 44 after subtracting 136 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
When dividing 440 by 68, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 6630.926
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
The number 68 fits into 320 4 times, leaving a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 6630.9264
If we take 272 away from 320, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
The number 68 fits into 480 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 6630.92647
If we take 476 away from 480, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
If we divide 40 by 68, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6630.92647
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
68 goes into 400 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 6630.9264705
The remainder is 60 after subtracting 340 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
The number 68 fits into 600 8 times, leaving a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 6630.92647058
The remainder is 56 after subtracting 544 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 6630.92647058 and a remainder of 5.6e-08.
