Let's divide 56553915 by 78
Let's see how many times 78 fits into 56553915.

On to step 1:
78 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 78

On to step 2:
78 can be fit into 56 0 times, resulting in a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 56 after subtracting 0 from 56.
Include the next digit (5) from the dividend after 56, then repeat: 565 / 78

Let's proceed to step 3:
565 divided by 78 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 546 from 565 leaves us with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 78

Moving on to step 4:
If we divide 195 by 78, we get 2 and a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we take 156 away from 195, we end up with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 78

Step 5:
78 goes into 393 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 725.0
Subtracting 390 from 393 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 78

On to step 6:
The number 78 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 7250.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 78

Going ahead to step 7:
The number 78 fits into 391 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 72505.0
Subtract 390 from 391 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 78

Moving on to step 8:
15 divided by 78 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 725050.0
If we take 0 away from 15, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
78 can be fit into 150 1 times, resulting in a remainder of 72.
The next digit of our result is 1. 
Result so far: 725050.1
If we take 78 away from 150, we end up 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.

Going ahead to step 10:
If we divide 720 by 78, we get 9 and a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 725050.19
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.

Let's proceed to step 11:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 725050.192
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.

Moving on to step 12:
240 divided by 78 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 725050.1923
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
78 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 725050.1923
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.

Advancing to step 14:
When dividing 600 by 78, we get 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 725050.192307
If we take 546 away from 600, we end up with 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 15:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 725050.1923076
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 16:
The number 78 fits into 720 9 times, leaving a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 725050.19230769
If we take 702 away from 720, 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.

After the division, we end up with 725050.19230769 and a remainder of 1.8e-08.
