64222280 ÷ 451 
We want to figure out the number of times 64222280 can be divided by 451.

Going ahead to step 1:
451 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 451

Moving on to step 2:
451 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 451

Step 3:
The number 451 fits into 642 1 times, leaving a remainder of 191.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 451 from 642, we get 191.
Grab the next digit (2) from the dividend, add it to 191, then carry on: 1912 / 451

Advancing to step 4:
451 goes into 1912 4 times with a remainder of 108.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 1804 from 1912 to get 108.
Bring next digit (2) of the dividend behind the 108 and repeat the process: 1082 / 451

Going ahead to step 5:
451 can be fit into 1082 2 times, resulting in a remainder of 180.
The next digit of our result is 2. 
Result so far: 142.0
If we subtract 902 from 1082, we get 180.
Bring next digit (2) of the dividend behind the 180 and repeat the process: 1802 / 451

Moving on to step 6:
The number 451 fits into 1802 3 times, leaving a remainder of 449.
The next digit of our result is 3. 
Result so far: 1423.0
If we subtract 1353 from 1802, we get 449.
Fetch the next digit (8) from the dividend, attach it to 449 and continue: 4498 / 451

Advancing to step 7:
The number 451 fits into 4498 9 times, leaving a remainder of 439.
Record the quotient 9 as the next digit in the result. 
Result so far: 14239.0
The remainder is 439 after subtracting 4059 from 4498.
Take the next digit (0) from the dividend and append it to 439, then repeat: 4390 / 451

Moving on to step 8:
4390 divided by 451 is 9 with a remainder of 331.
Put 9 as the next digit of the answer. 
Result so far: 142399.0
Subtract 4059 from 4390 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 9:
3310 divided by 451 is 7 with a remainder of 153.
The number 7 becomes the next digit in our result. 
Result so far: 142399.7
Deduct 3157 from 3310 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 10:
When dividing 1530 by 451, we get 3 with a remainder of 177.
Use 3 as the next digit of our solution. 
Result so far: 142399.73
The remainder is 177 after subtracting 1353 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 11:
The number 451 fits into 1770 3 times, leaving a remainder of 417.
Use 3 as the next digit of our solution. 
Result so far: 142399.733
The remainder is 417 after subtracting 1353 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Our division results in 142399.733 with a remaining 0.0417.
