We're dividing 66199725 by 454 
We're looking to find how many times 454 goes into 66199725.

Let's proceed to step 1:
The number 454 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 454

Advancing to step 2:
If we divide 66 by 454, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 454

Let's proceed to step 3:
The number 454 fits into 661 1 times, leaving a remainder of 207.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 454 from 661 to get 207.
Bring next digit (9) of the dividend behind the 207 and repeat the process: 2079 / 454

Let's proceed to step 4:
2079 divided by 454 is 4 with a remainder of 263.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 1816 away from 2079, we end up with 263.
Include the next digit (9) from the dividend after 263, then repeat: 2639 / 454

Advancing to step 5:
2639 divided by 454 is 5 with a remainder of 369.
Write down 5 as next digit of the result. 
Result so far: 145.0
Subtracting 2270 from 2639 leaves us with 369.
Include the next digit (7) from the dividend after 369, then repeat: 3697 / 454

Let's proceed to step 6:
The number 454 fits into 3697 8 times, leaving a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 1458.0
Subtract 3632 from 3697 to get 65.
Fetch the next digit (2) from the dividend, attach it to 65 and continue: 652 / 454

Advancing to step 7:
454 goes into 652 1 times with a remainder of 198.
Write down 1 as next digit of the result. 
Result so far: 14581.0
The remainder is 198 after subtracting 454 from 652.
Fetch the next digit (5) from the dividend, attach it to 198 and continue: 1985 / 454

Step 8:
454 goes into 1985 4 times with a remainder of 169.
Put 4 as the next digit of the answer. 
Result so far: 145814.0
Deduct 1816 from 1985 and we're left with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 9:
If we divide 1690 by 454, we get 3 and a remainder of 328.
Write down 3 as next digit of the result. 
Result so far: 145814.3
If we subtract 1362 from 1690, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 10:
The number 454 fits into 3280 7 times, leaving a remainder of 102.
The number 7 becomes the next digit in our result. 
Result so far: 145814.37
Subtract 3178 from 3280 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 11:
The number 454 fits into 1020 2 times, leaving a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 145814.372
The remainder is 112 after subtracting 908 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
The number 454 fits into 1120 2 times, leaving a remainder of 212.
The number 2 becomes the next digit in our result. 
Result so far: 145814.3722
Deduct 908 from 1120 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final result is 145814.3722 with a remainder of 0.00212.
