Let's divide 353685 by 78
Let's see how many times 78 fits into 353685.

Going ahead to step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 78

Moving on to step 2:
The number 78 fits into 35 0 times, leaving a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 78

On to step 3:
78 can be fit into 353 4 times, resulting in a remainder of 41.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 312 from 353 to get 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 78

Step 4:
416 divided by 78 is 5 with a remainder of 26.
The next digit of our result is 5. 
Result so far: 45.0
If we take 390 away from 416, we end up with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 78

Advancing to step 5:
268 divided by 78 is 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 453.0
The remainder is 34 after subtracting 234 from 268.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 78

Let's proceed to step 6:
78 goes into 345 4 times with a remainder of 33.
The next digit of our result is 4. 
Result so far: 4534.0
The remainder is 33 after subtracting 312 from 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
78 can be fit into 330 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 4534.4
If we subtract 312 from 330, 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.

Going ahead to step 8:
If we divide 180 by 78, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 4534.42
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.

On to step 9:
If we divide 240 by 78, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 4534.423
If we take 234 away from 240, we end up with 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 10:
78 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 4534.423
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.

Let's proceed to step 11:
When dividing 600 by 78, we get 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 4534.42307
Subtracting 546 from 600 leaves us 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.

Moving on to step 12:
When dividing 540 by 78, we get 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 4534.423076
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.

On to step 13:
78 goes into 720 9 times with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 4534.4230769
Subtract 702 from 720 to 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.

Going ahead to step 14:
78 goes into 180 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 4534.42307692
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.

The final outcome is 4534.42307692, with a leftover of 2.4e-08.
