Let's divide 350288 by 78
We want to divide 350288 by 78.

On to step 1:
78 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 78

Let's proceed to step 2:
78 can be fit into 35 0 times, resulting in a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 78

Advancing to step 3:
When dividing 350 by 78, we get 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 312 from 350 to get 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 78

Step 4:
382 divided by 78 is 4 with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we take 312 away from 382, we end up with 70.
Bring next digit (8) of the dividend behind the 70 and repeat the process: 708 / 78

Step 5:
When dividing 708 by 78, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 449.0
Subtracting 702 from 708 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 78

Going ahead to step 6:
If we divide 68 by 78, we get 0 and a remainder of 68.
The next digit of our result is 0. 
Result so far: 4490.0
Subtract 0 from 68 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 7:
If we divide 680 by 78, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 4490.8
Deduct 624 from 680 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
560 divided by 78 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 4490.87
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 4490.871
Subtracting 78 from 140 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
If we divide 620 by 78, we get 7 and a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 4490.8717
The remainder is 74 after subtracting 546 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 11:
When dividing 740 by 78, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 4490.87179
Subtracting 702 from 740 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 4490.871794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
78 can be fit into 680 8 times, resulting in a remainder of 56.
The next digit of our result is 8. 
Result so far: 4490.8717948
If we subtract 624 from 680, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
If we divide 560 by 78, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 4490.87179487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 4490.87179487, with a leftover of 1.4e-08.
