353512 ÷ 78 
Let's see how many times 78 fits into 353512.

Advancing to step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 78

Let's proceed to step 2:
The number 78 fits into 35 0 times, leaving a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 78

Advancing to step 3:
The number 78 fits into 353 4 times, leaving a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 312 from 353, we get 41.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 78

On to step 4:
When dividing 415 by 78, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 390 from 415 leaves us with 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 78

Step 5:
78 can be fit into 251 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 453.0
If we subtract 234 from 251, we get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 78

Step 6:
The number 78 fits into 172 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 4532.0
Subtracting 156 from 172 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 78, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 4532.2
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
40 divided by 78 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4532.2
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
When dividing 400 by 78, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 4532.205
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
100 divided by 78 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 4532.2051
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 4532.20512
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
78 goes into 640 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 4532.205128
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
78 can be fit into 160 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 4532.2051282
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
If we divide 40 by 78, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4532.2051282
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 4532.2051282 with a remainder of 4e-08.
