We're dividing 577405 by 78 
Our goal is to divide 577405 by 78.

Step 1:
If we divide 5 by 78, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 78

Advancing to step 2:
If we divide 57 by 78, we get 0 and a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 78

Moving on to step 3:
When dividing 577 by 78, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 546 away from 577, we end up with 31.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 78

Moving on to step 4:
78 can be fit into 314 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
If we subtract 312 from 314, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 78

Let's proceed to step 5:
If we divide 20 by 78, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 740.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 78

Step 6:
78 can be fit into 205 2 times, resulting in a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 7402.0
The remainder is 49 after subtracting 156 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
If we divide 490 by 78, we get 6 and a remainder of 22.
The next digit of our result is 6. 
Result so far: 7402.6
Subtracting 468 from 490 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.

Advancing to step 8:
When dividing 220 by 78, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 7402.62
If we subtract 156 from 220, we 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.

On to step 9:
When dividing 640 by 78, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 7402.628
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.

Step 10:
If we divide 160 by 78, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 7402.6282
If we take 156 away from 160, we end up 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.

Step 11:
40 divided by 78 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7402.6282
Subtracting 0 from 40 leaves us 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.

On to step 12:
400 divided by 78 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7402.628205
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.

Step 13:
78 can be fit into 100 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 7402.6282051
Deduct 78 from 100 and we're left 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.

Advancing to step 14:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 7402.62820512
If we subtract 156 from 220, we 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.

The final result is 7402.62820512 with a remainder of 6.4e-08.
