We look at the division of 356640 by 78 
We want to divide 356640 by 78.

On to step 1:
3 divided by 78 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 78

On to step 2:
If we divide 35 by 78, we get 0 and a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 78

Step 3:
When dividing 356 by 78, we get 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 44 after subtracting 312 from 356.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 78

Going ahead to step 4:
If we divide 446 by 78, we get 5 and a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 45.0
The remainder is 56 after subtracting 390 from 446.
Take the next digit (4) from the dividend and append it to 56, then repeat: 564 / 78

Advancing to step 5:
The number 78 fits into 564 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 457.0
The remainder is 18 after subtracting 546 from 564.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 78

Step 6:
180 divided by 78 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 4572.0
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
When dividing 240 by 78, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 4572.3
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.

Step 8:
When dividing 60 by 78, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 4572.3
Subtracting 0 from 60 leaves us 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.

Advancing to step 9:
600 divided by 78 is 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 4572.307
If we take 546 away from 600, we end up 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.

Going ahead to step 10:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 4572.3076
The remainder is 72 after subtracting 468 from 540.
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 11:
78 can be fit into 720 9 times, resulting in a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 4572.30769
Subtracting 702 from 720 leaves us 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.

Moving on to step 12:
78 goes into 180 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 4572.307692
If we take 156 away from 180, we end up 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.

Going ahead to step 13:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 4572.3076923
If we subtract 234 from 240, we 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.

Let's proceed to step 14:
When dividing 60 by 78, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 4572.3076923
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.

The final outcome is 4572.3076923, with a leftover of 6e-08.
