We're dividing 904521 by 78 
Our goal is to divide 904521 by 78.

On to step 1:
When dividing 9 by 78, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 78

Going ahead to step 2:
If we divide 90 by 78, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 78 from 90 to get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 78

Going ahead to step 3:
78 can be fit into 124 1 times, resulting in a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 78 from 124 and we're left with 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 78

Step 4:
78 goes into 465 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 115.0
The remainder is 75 after subtracting 390 from 465.
Grab the next digit (2) from the dividend, add it to 75, then carry on: 752 / 78

Advancing to step 5:
If we divide 752 by 78, we get 9 and a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 1159.0
Subtracting 702 from 752 leaves us with 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 78

Going ahead to step 6:
When dividing 501 by 78, we get 6 with a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 11596.0
Deduct 468 from 501 and we're left 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.

Advancing to step 7:
The number 78 fits into 330 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 11596.4
If we subtract 312 from 330, 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.

Going ahead to step 8:
When dividing 180 by 78, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 11596.42
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
If we divide 240 by 78, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 11596.423
If we take 234 away from 240, we end up 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.

On to step 10:
60 divided by 78 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 11596.423
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
The number 78 fits into 600 7 times, leaving a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 11596.42307
If we subtract 546 from 600, we 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.

Going ahead to step 12:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 11596.423076
Deduct 468 from 540 and we're left 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.

Step 13:
If we divide 720 by 78, we get 9 and a remainder of 18.
The next digit of our result is 9. 
Result so far: 11596.4230769
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.

Moving on to step 14:
The number 78 fits into 180 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 11596.42307692
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 11596.42307692 and a remainder of 2.4e-08.
