We're dividing 68531409 by 456 
Let's see how many times 456 fits into 68531409.

Step 1:
456 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 456

Moving on to step 2:
456 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 456

On to step 3:
The number 456 fits into 685 1 times, leaving a remainder of 229.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 456 from 685 to get 229.
Fetch the next digit (3) from the dividend, attach it to 229 and continue: 2293 / 456

Let's proceed to step 4:
456 can be fit into 2293 5 times, resulting in a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 2280 from 2293 leaves us with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 456

Going ahead to step 5:
The number 456 fits into 131 0 times, leaving a remainder of 131.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Subtract 0 from 131 to get 131.
Bring next digit (4) of the dividend behind the 131 and repeat the process: 1314 / 456

On to step 6:
When dividing 1314 by 456, we get 2 with a remainder of 402.
Put 2 as the next digit of the answer. 
Result so far: 1502.0
If we take 912 away from 1314, we end up with 402.
Take the next digit (0) from the dividend and append it to 402, then repeat: 4020 / 456

On to step 7:
4020 divided by 456 is 8 with a remainder of 372.
Write down 8 as next digit of the result. 
Result so far: 15028.0
Subtract 3648 from 4020 to get 372.
Grab the next digit (9) from the dividend, add it to 372, then carry on: 3729 / 456

Moving on to step 8:
If we divide 3729 by 456, we get 8 and a remainder of 81.
The next digit of our result is 8. 
Result so far: 150288.0
The remainder is 81 after subtracting 3648 from 3729.
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:
456 goes into 810 1 times with a remainder of 354.
Use 1 as the next digit of our solution. 
Result so far: 150288.1
The remainder is 354 after subtracting 456 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 10:
456 can be fit into 3540 7 times, resulting in a remainder of 348.
Write down 7 as next digit of the result. 
Result so far: 150288.17
Subtract 3192 from 3540 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 11:
When dividing 3480 by 456, we get 7 with a remainder of 288.
Put 7 as the next digit of the answer. 
Result so far: 150288.177
Subtract 3192 from 3480 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 150288.177, with a leftover of 0.0288.
