We look at the division of 455378 by 72 
We want to divide 455378 by 72.

On to step 1:
The number 72 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 72

Advancing to step 2:
45 divided by 72 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 72

Going ahead to step 3:
455 divided by 72 is 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 432 from 455 and we're left with 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 72

Let's proceed to step 4:
When dividing 233 by 72, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 63.0
If we take 216 away from 233, we end up with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 72

Moving on to step 5:
The number 72 fits into 177 2 times, leaving a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 632.0
Subtract 144 from 177 to get 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 72

On to step 6:
72 can be fit into 338 4 times, resulting in a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 6324.0
Subtract 288 from 338 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
If we divide 500 by 72, we get 6 and a remainder of 68.
The next digit of our result is 6. 
Result so far: 6324.6
Subtract 432 from 500 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
The number 72 fits into 680 9 times, leaving a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 6324.69
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
320 divided by 72 is 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 6324.694
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 6324.6944
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 6324.6944, and the remainder is 0.00032.
