445551 divided by 78 
Our goal is to divide 445551 by 78.

Moving on to step 1:
78 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 78

Let's proceed to step 2:
78 can be fit into 44 0 times, resulting in a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 78

Going ahead to step 3:
The number 78 fits into 445 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 390 from 445 and we're left with 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 78

On to step 4:
78 goes into 555 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Subtracting 546 from 555 leaves us with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 78

Let's proceed to step 5:
The number 78 fits into 95 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 571.0
If we take 78 away from 95, we end up with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 78

On to step 6:
78 goes into 171 2 times with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 5712.0
Subtract 156 from 171 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
When dividing 150 by 78, we get 1 with a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 5712.1
The remainder is 72 after subtracting 78 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 8:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 5712.19
Subtracting 702 from 720 leaves us 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.

Moving on to step 9:
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: 5712.192
Subtract 156 from 180 to 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.

Let's proceed to step 10:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 5712.1923
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.

Step 11:
When dividing 60 by 78, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 5712.1923
Subtract 0 from 60 to get 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 12:
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: 5712.192307
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.

On to step 13:
540 divided by 78 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 5712.1923076
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.

Advancing to step 14:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 5712.19230769
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.

The final outcome is 5712.19230769, with a leftover of 1.8e-08.
