453897 ÷ 78 
Our goal is to divide 453897 by 78.

Step 1:
When dividing 4 by 78, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 78

Advancing to step 2:
78 can be fit into 45 0 times, resulting in a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 78

Advancing to step 3:
78 can be fit into 453 5 times, resulting in a remainder of 63.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 390 from 453 and we're left with 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 78

Moving on to step 4:
78 goes into 638 8 times with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 58.0
Subtract 624 from 638 to get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 78

Moving on to step 5:
149 divided by 78 is 1 with a remainder of 71.
The next digit of our result is 1. 
Result so far: 581.0
If we take 78 away from 149, we end up with 71.
Append the next digit (7) from the dividend to 71 and continue with: 717 / 78

Going ahead to step 6:
78 can be fit into 717 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 5819.0
If we subtract 702 from 717, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
78 can be fit into 150 1 times, resulting in a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 5819.1
If we take 78 away from 150, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 8:
78 can be fit into 720 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 5819.19
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
If we divide 180 by 78, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 5819.192
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
240 divided by 78 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 5819.1923
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
If we divide 60 by 78, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 5819.1923
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
78 goes into 600 7 times with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 5819.192307
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
540 divided by 78 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 5819.1923076
If we take 468 away from 540, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 5819.19230769
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 5819.19230769 with a remaining 1.8e-08.
