We're dividing 530121 by 78 
We want to divide 530121 by 78.

Let's proceed to step 1:
If we divide 5 by 78, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 78

Moving on to step 2:
If we divide 53 by 78, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Grab the next digit (0) from the dividend, add it to 53, then carry on: 530 / 78

Let's proceed to step 3:
If we divide 530 by 78, we get 6 and a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 468 from 530 to get 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 78

On to step 4:
If we divide 621 by 78, we get 7 and a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 67.0
Subtract 546 from 621 to get 75.
Append the next digit (2) from the dividend to 75 and continue with: 752 / 78

On to step 5:
752 divided by 78 is 9 with a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 679.0
If we subtract 702 from 752, we get 50.
Append the next digit (1) from the dividend to 50 and continue with: 501 / 78

Step 6:
If we divide 501 by 78, we get 6 and a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 6796.0
If we take 468 away from 501, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
If we divide 330 by 78, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 6796.4
If we take 312 away from 330, we end up with 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 8:
78 can be fit into 180 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 6796.42
Subtracting 156 from 180 leaves us 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.

Advancing to step 9:
78 can be fit into 240 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 6796.423
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
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: 6796.423
If we take 0 away from 60, we end up 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.

Moving on to step 11:
If we divide 600 by 78, we get 7 and a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 6796.42307
Subtract 546 from 600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 6796.423076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 13:
When dividing 720 by 78, we get 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 6796.4230769
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.

Step 14:
If we divide 180 by 78, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 6796.42307692
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.

Our division results in 6796.42307692 with a remaining 2.4e-08.
