Let's divide 66435270 by 457
We're looking to find how many times 457 goes into 66435270.

Moving on to step 1:
457 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 457

Moving on to step 2:
If we divide 66 by 457, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 457

Moving on to step 3:
664 divided by 457 is 1 with a remainder of 207.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 457 from 664 to get 207.
Append the next digit (3) from the dividend to 207 and continue with: 2073 / 457

Moving on to step 4:
2073 divided by 457 is 4 with a remainder of 245.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 1828 from 2073 to get 245.
Bring next digit (5) of the dividend behind the 245 and repeat the process: 2455 / 457

Step 5:
If we divide 2455 by 457, we get 5 and a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 145.0
Subtracting 2285 from 2455 leaves us with 170.
Bring next digit (2) of the dividend behind the 170 and repeat the process: 1702 / 457

On to step 6:
457 can be fit into 1702 3 times, resulting in a remainder of 331.
Put 3 as the next digit of the answer. 
Result so far: 1453.0
If we take 1371 away from 1702, we end up with 331.
Fetch the next digit (7) from the dividend, attach it to 331 and continue: 3317 / 457

Let's proceed to step 7:
When dividing 3317 by 457, we get 7 with a remainder of 118.
The next digit of our result is 7. 
Result so far: 14537.0
Deduct 3199 from 3317 and we're left with 118.
Include the next digit (0) from the dividend after 118, then repeat: 1180 / 457

Let's proceed to step 8:
If we divide 1180 by 457, we get 2 and a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 145372.0
The remainder is 266 after subtracting 914 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 9:
If we divide 2660 by 457, we get 5 and a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 145372.5
The remainder is 375 after subtracting 2285 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 10:
The number 457 fits into 3750 8 times, leaving a remainder of 94.
Use 8 as the next digit of our solution. 
Result so far: 145372.58
If we take 3656 away from 3750, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 11:
457 can be fit into 940 2 times, resulting in a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 145372.582
If we take 914 away from 940, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
The number 457 fits into 260 0 times, leaving a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 145372.582
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 13:
457 can be fit into 2600 5 times, resulting in a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 145372.58205
Subtracting 2285 from 2600 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 14:
When dividing 3150 by 457, we get 6 with a remainder of 408.
Write down 6 as next digit of the result. 
Result so far: 145372.582056
Deduct 2742 from 3150 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 15:
4080 divided by 457 is 8 with a remainder of 424.
Write down 8 as next digit of the result. 
Result so far: 145372.5820568
If we subtract 3656 from 4080, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 16:
457 goes into 4240 9 times with a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 145372.58205689
Subtract 4113 from 4240 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Our division results in 145372.58205689 with a remaining 1.27e-07.
