We're dividing 66030406 by 455 
We're looking to find how many times 455 goes into 66030406.

Let's proceed to step 1:
The number 455 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 455

Going ahead to step 2:
455 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 455

Moving on to step 3:
455 goes into 660 1 times with a remainder of 205.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 455 from 660, we get 205.
Take the next digit (3) from the dividend and append it to 205, then repeat: 2053 / 455

Going ahead to step 4:
If we divide 2053 by 455, we get 4 and a remainder of 233.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 1820 from 2053 leaves us with 233.
Bring next digit (0) of the dividend behind the 233 and repeat the process: 2330 / 455

Going ahead to step 5:
455 goes into 2330 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 145.0
Subtract 2275 from 2330 to get 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 455

On to step 6:
The number 455 fits into 554 1 times, leaving a remainder of 99.
Use 1 as the next digit of our solution. 
Result so far: 1451.0
The remainder is 99 after subtracting 455 from 554.
Grab the next digit (0) from the dividend, add it to 99, then carry on: 990 / 455

Let's proceed to step 7:
If we divide 990 by 455, we get 2 and a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 14512.0
Deduct 910 from 990 and we're left with 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 455

Let's proceed to step 8:
The number 455 fits into 806 1 times, leaving a remainder of 351.
The next digit of our result is 1. 
Result so far: 145121.0
The remainder is 351 after subtracting 455 from 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 9:
When dividing 3510 by 455, we get 7 with a remainder of 325.
The next digit of our result is 7. 
Result so far: 145121.7
If we subtract 3185 from 3510, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 10:
3250 divided by 455 is 7 with a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 145121.77
The remainder is 65 after subtracting 3185 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 145121.77 with a remaining 0.065.
