424945 ÷ 78 
Our goal is to divide 424945 by 78.

On to step 1:
The number 78 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 78

Advancing to step 2:
78 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 78

Advancing to step 3:
424 divided by 78 is 5 with a remainder of 34.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 390 from 424, we get 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 78

Going ahead to step 4:
When dividing 349 by 78, we get 4 with a remainder of 37.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we subtract 312 from 349, we get 37.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 78

On to step 5:
The number 78 fits into 374 4 times, leaving a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 544.0
Deduct 312 from 374 and we're left with 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 78

Step 6:
78 can be fit into 625 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 5448.0
The remainder is 1 after subtracting 624 from 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 78, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 5448.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
78 can be fit into 100 1 times, resulting in a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 5448.01
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
220 divided by 78 is 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 5448.012
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
The number 78 fits into 640 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 5448.0128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
When dividing 160 by 78, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 5448.01282
If we subtract 156 from 160, 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 12:
If we divide 40 by 78, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 5448.01282
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
400 divided by 78 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 5448.0128205
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
100 divided by 78 is 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 5448.01282051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 5448.01282051 with a remainder of 2.2e-08.
