478921 ÷ 78 
Our goal is to divide 478921 by 78.

Going ahead to step 1:
If we divide 4 by 78, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 78

On to step 2:
The number 78 fits into 47 0 times, leaving a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 78

Step 3:
78 can be fit into 478 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 10 after subtracting 468 from 478.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 78

Moving on to step 4:
78 goes into 109 1 times with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Deduct 78 from 109 and we're left with 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 78

Going ahead to step 5:
When dividing 312 by 78, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 614.0
If we take 312 away from 312, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 78

Advancing to step 6:
78 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 6140.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 78, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 6140.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
78 goes into 100 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 6140.01
Subtract 78 from 100 to get 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:
78 goes into 220 2 times with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 6140.012
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
78 goes into 640 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 6140.0128
Subtracting 624 from 640 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
If we divide 160 by 78, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 6140.01282
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
40 divided by 78 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 6140.01282
If we subtract 0 from 40, we 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.

Step 13:
The number 78 fits into 400 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 6140.0128205
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.

Moving on to step 14:
78 goes into 100 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 6140.01282051
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 6140.01282051 with a remaining 2.2e-08.
