We're dividing 78132412 by 456 
We want to divide 78132412 by 456.

Advancing to step 1:
456 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 456

Let's proceed to step 2:
456 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 456

On to step 3:
The number 456 fits into 781 1 times, leaving a remainder of 325.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 456 from 781 to get 325.
Append the next digit (3) from the dividend to 325 and continue with: 3253 / 456

Going ahead to step 4:
The number 456 fits into 3253 7 times, leaving a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 3192 from 3253 to get 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 456

Step 5:
612 divided by 456 is 1 with a remainder of 156.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Deduct 456 from 612 and we're left with 156.
Grab the next digit (4) from the dividend, add it to 156, then carry on: 1564 / 456

Advancing to step 6:
456 goes into 1564 3 times with a remainder of 196.
Record the quotient 3 as the next digit in the result. 
Result so far: 1713.0
Subtracting 1368 from 1564 leaves us with 196.
Bring next digit (1) of the dividend behind the 196 and repeat the process: 1961 / 456

Going ahead to step 7:
The number 456 fits into 1961 4 times, leaving a remainder of 137.
The number 4 becomes the next digit in our result. 
Result so far: 17134.0
Subtracting 1824 from 1961 leaves us with 137.
Grab the next digit (2) from the dividend, add it to 137, then carry on: 1372 / 456

Moving on to step 8:
When dividing 1372 by 456, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 171343.0
If we subtract 1368 from 1372, we 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 9:
456 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 171343.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
400 divided by 456 is 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 171343.0
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 171343.0, and the remainder is 0.4.
