67840424 ÷ 456 
Our goal is to divide 67840424 by 456.

Advancing to step 1:
456 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 456

Let's proceed to step 2:
If we divide 67 by 456, we get 0 and a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 456

On to step 3:
456 can be fit into 678 1 times, resulting in a remainder of 222.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 456 away from 678, we end up with 222.
Bring next digit (4) of the dividend behind the 222 and repeat the process: 2224 / 456

Going ahead to step 4:
The number 456 fits into 2224 4 times, leaving a remainder of 400.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 1824 from 2224 leaves us with 400.
Take the next digit (0) from the dividend and append it to 400, then repeat: 4000 / 456

Step 5:
The number 456 fits into 4000 8 times, leaving a remainder of 352.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
If we take 3648 away from 4000, we end up with 352.
Include the next digit (4) from the dividend after 352, then repeat: 3524 / 456

Moving on to step 6:
The number 456 fits into 3524 7 times, leaving a remainder of 332.
The number 7 becomes the next digit in our result. 
Result so far: 1487.0
Subtracting 3192 from 3524 leaves us with 332.
Grab the next digit (2) from the dividend, add it to 332, then carry on: 3322 / 456

Advancing to step 7:
456 goes into 3322 7 times with a remainder of 130.
Record the quotient 7 as the next digit in the result. 
Result so far: 14877.0
Deduct 3192 from 3322 and we're left with 130.
Bring next digit (4) of the dividend behind the 130 and repeat the process: 1304 / 456

Let's proceed to step 8:
When dividing 1304 by 456, we get 2 with a remainder of 392.
The next digit of our result is 2. 
Result so far: 148772.0
If we subtract 912 from 1304, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 9:
When dividing 3920 by 456, we get 8 with a remainder of 272.
Use 8 as the next digit of our solution. 
Result so far: 148772.8
Subtracting 3648 from 3920 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 10:
The number 456 fits into 2720 5 times, leaving a remainder of 440.
Record the quotient 5 as the next digit in the result. 
Result so far: 148772.85
Subtracting 2280 from 2720 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 11:
The number 456 fits into 4400 9 times, leaving a remainder of 296.
The next digit of our result is 9. 
Result so far: 148772.859
Subtracting 4104 from 4400 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 12:
The number 456 fits into 2960 6 times, leaving a remainder of 224.
Write down 6 as next digit of the result. 
Result so far: 148772.8596
If we take 2736 away from 2960, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 13:
The number 456 fits into 2240 4 times, leaving a remainder of 416.
Record the quotient 4 as the next digit in the result. 
Result so far: 148772.85964
Subtract 1824 from 2240 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 14:
456 goes into 4160 9 times with a remainder of 56.
The next digit of our result is 9. 
Result so far: 148772.859649
If we take 4104 away from 4160, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 15:
If we divide 560 by 456, we get 1 and a remainder of 104.
The number 1 becomes the next digit in our result. 
Result so far: 148772.8596491
Subtracting 456 from 560 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 16:
If we divide 1040 by 456, we get 2 and a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 148772.85964912
The remainder is 128 after subtracting 912 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

After the division, we end up with 148772.85964912 and a remainder of 1.28e-07.
