Let's divide 450317 by 78
We're looking to find how many times 78 goes into 450317.

Going ahead to step 1:
If we divide 4 by 78, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 78

Going ahead to step 2:
If we divide 45 by 78, we get 0 and a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 78

On to step 3:
The number 78 fits into 450 5 times, leaving a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 390 from 450, we get 60.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 78

Let's proceed to step 4:
If we divide 603 by 78, we get 7 and a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 57.0
If we take 546 away from 603, we end up with 57.
Fetch the next digit (1) from the dividend, attach it to 57 and continue: 571 / 78

Advancing to step 5:
78 can be fit into 571 7 times, resulting in a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 577.0
If we subtract 546 from 571, we get 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 78

Let's proceed to step 6:
78 can be fit into 257 3 times, resulting in a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 5773.0
Subtract 234 from 257 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
The number 78 fits into 230 2 times, leaving a remainder of 74.
The next digit of our result is 2. 
Result so far: 5773.2
Deduct 156 from 230 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 8:
When dividing 740 by 78, we get 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 5773.29
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
If we divide 380 by 78, we get 4 and a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 5773.294
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
If we divide 680 by 78, we get 8 and a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 5773.2948
If we take 624 away from 680, 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.

Step 11:
When dividing 560 by 78, we get 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 5773.29487
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
78 goes into 140 1 times with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 5773.294871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
620 divided by 78 is 7 with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 5773.2948717
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 14:
78 can be fit into 740 9 times, resulting in a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 5773.29487179
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 5773.29487179 with a remaining 3.8e-08.
