We're dividing 429999 by 78 
Our goal is to divide 429999 by 78.

On to step 1:
If we divide 4 by 78, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 78

Advancing to step 2:
The number 78 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 78

Moving on to step 3:
When dividing 429 by 78, we get 5 with a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 39 after subtracting 390 from 429.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 78

On to step 4:
78 can be fit into 399 5 times, resulting in a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Deduct 390 from 399 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 78

Let's proceed to step 5:
78 can be fit into 99 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 551.0
Subtracting 78 from 99 leaves us with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 78

On to step 6:
78 can be fit into 219 2 times, resulting in a remainder of 63.
Put 2 as the next digit of the answer. 
Result so far: 5512.0
Subtract 156 from 219 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
630 divided by 78 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 5512.8
Subtract 624 from 630 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 78, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 5512.8
If we subtract 0 from 60, we 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 9:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 5512.807
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.

Step 10:
540 divided by 78 is 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 5512.8076
If we take 468 away from 540, 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.

Let's proceed to step 11:
78 goes into 720 9 times with a remainder of 18.
The next digit of our result is 9. 
Result so far: 5512.80769
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.

Step 12:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 5512.807692
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.

On to step 13:
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: 5512.8076923
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
When dividing 60 by 78, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 5512.8076923
Deduct 0 from 60 and we're left 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.

After the division, we end up with 5512.8076923 and a remainder of 6e-08.
