We divide 66605565 by 451
We want to figure out the number of times 66605565 can be divided by 451.

Step 1:
If we divide 6 by 451, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 451

Advancing to step 2:
The number 451 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 451

Going ahead to step 3:
If we divide 666 by 451, we get 1 and a remainder of 215.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 451 from 666 to get 215.
Include the next digit (0) from the dividend after 215, then repeat: 2150 / 451

Let's proceed to step 4:
2150 divided by 451 is 4 with a remainder of 346.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 346 after subtracting 1804 from 2150.
Take the next digit (5) from the dividend and append it to 346, then repeat: 3465 / 451

Let's proceed to step 5:
3465 divided by 451 is 7 with a remainder of 308.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
Subtracting 3157 from 3465 leaves us with 308.
Bring next digit (5) of the dividend behind the 308 and repeat the process: 3085 / 451

Advancing to step 6:
When dividing 3085 by 451, we get 6 with a remainder of 379.
Write down 6 as next digit of the result. 
Result so far: 1476.0
Deduct 2706 from 3085 and we're left with 379.
Grab the next digit (6) from the dividend, add it to 379, then carry on: 3796 / 451

Step 7:
451 goes into 3796 8 times with a remainder of 188.
Record the quotient 8 as the next digit in the result. 
Result so far: 14768.0
Subtracting 3608 from 3796 leaves us with 188.
Include the next digit (5) from the dividend after 188, then repeat: 1885 / 451

Step 8:
451 can be fit into 1885 4 times, resulting in a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 147684.0
The remainder is 81 after subtracting 1804 from 1885.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 9:
The number 451 fits into 810 1 times, leaving a remainder of 359.
Use 1 as the next digit of our solution. 
Result so far: 147684.1
If we take 451 away from 810, we end up with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Step 10:
3590 divided by 451 is 7 with a remainder of 433.
The number 7 becomes the next digit in our result. 
Result so far: 147684.17
If we subtract 3157 from 3590, we get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Going ahead to step 11:
If we divide 4330 by 451, we get 9 and a remainder of 271.
Put 9 as the next digit of the answer. 
Result so far: 147684.179
If we subtract 4059 from 4330, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 12:
If we divide 2710 by 451, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 147684.1796
Subtract 2706 from 2710 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
When dividing 40 by 451, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 147684.1796
The remainder is 40 after subtracting 0 from 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 14:
If we divide 400 by 451, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 147684.1796
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 147684.1796 with a balance of 4e-05.
