66842256 ÷ 451 
Let's see how many times 451 fits into 66842256.

Going ahead to step 1:
The number 451 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 451

Going ahead to step 2:
When dividing 66 by 451, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 451

Step 3:
451 can be fit into 668 1 times, resulting in a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 217 after subtracting 451 from 668.
Take the next digit (4) from the dividend and append it to 217, then repeat: 2174 / 451

Advancing to step 4:
The number 451 fits into 2174 4 times, leaving a remainder of 370.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 1804 from 2174 to get 370.
Fetch the next digit (2) from the dividend, attach it to 370 and continue: 3702 / 451

Advancing to step 5:
451 goes into 3702 8 times with a remainder of 94.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
Subtracting 3608 from 3702 leaves us with 94.
Grab the next digit (2) from the dividend, add it to 94, then carry on: 942 / 451

Step 6:
451 can be fit into 942 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 1482.0
Subtracting 902 from 942 leaves us with 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 451

On to step 7:
When dividing 405 by 451, we get 0 with a remainder of 405.
The next digit of our result is 0. 
Result so far: 14820.0
Subtracting 0 from 405 leaves us with 405.
Append the next digit (6) from the dividend to 405 and continue with: 4056 / 451

Moving on to step 8:
If we divide 4056 by 451, we get 8 and a remainder of 448.
Write down 8 as next digit of the result. 
Result so far: 148208.0
Subtract 3608 from 4056 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 9:
If we divide 4480 by 451, we get 9 and a remainder of 421.
Put 9 as the next digit of the answer. 
Result so far: 148208.9
If we subtract 4059 from 4480, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Going ahead to step 10:
4210 divided by 451 is 9 with a remainder of 151.
The number 9 becomes the next digit in our result. 
Result so far: 148208.99
Subtract 4059 from 4210 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

In conclusion, the division gives 148208.99 with a balance of 0.151.
