78642646 ÷ 479 
We want to divide 78642646 by 479.

Moving on to step 1:
When dividing 7 by 479, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 479

Advancing to step 2:
78 divided by 479 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 479

Step 3:
The number 479 fits into 786 1 times, leaving a remainder of 307.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 307 after subtracting 479 from 786.
Append the next digit (4) from the dividend to 307 and continue with: 3074 / 479

Moving on to step 4:
479 goes into 3074 6 times with a remainder of 200.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 2874 away from 3074, we end up with 200.
Include the next digit (2) from the dividend after 200, then repeat: 2002 / 479

Going ahead to step 5:
The number 479 fits into 2002 4 times, leaving a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 164.0
Subtract 1916 from 2002 to get 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 479

Moving on to step 6:
The number 479 fits into 866 1 times, leaving a remainder of 387.
Use 1 as the next digit of our solution. 
Result so far: 1641.0
If we take 479 away from 866, we end up with 387.
Bring next digit (4) of the dividend behind the 387 and repeat the process: 3874 / 479

Moving on to step 7:
479 can be fit into 3874 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 16418.0
Subtracting 3832 from 3874 leaves us with 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 479

Advancing to step 8:
479 goes into 426 0 times with a remainder of 426.
Use 0 as the next digit of our solution. 
Result so far: 164180.0
If we subtract 0 from 426, we get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 9:
479 can be fit into 4260 8 times, resulting in a remainder of 428.
The next digit of our result is 8. 
Result so far: 164180.8
Subtract 3832 from 4260 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 10:
The number 479 fits into 4280 8 times, leaving a remainder of 448.
The next digit of our result is 8. 
Result so far: 164180.88
Subtract 3832 from 4280 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Our division results in 164180.88 with a remaining 0.448.
