Let's divide 286393 by 78
Our goal is to divide 286393 by 78.

Advancing to step 1:
78 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 78

Let's proceed to step 2:
28 divided by 78 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 78

On to step 3:
When dividing 286 by 78, we get 3 with a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 52 after subtracting 234 from 286.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 78

On to step 4:
When dividing 523 by 78, we get 6 with a remainder of 55.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtract 468 from 523 to get 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 78

Step 5:
78 goes into 559 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 367.0
If we subtract 546 from 559, we get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 78

Advancing to step 6:
When dividing 133 by 78, we get 1 with a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 3671.0
The remainder is 55 after subtracting 78 from 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
The number 78 fits into 550 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 3671.7
If we subtract 546 from 550, 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 8:
78 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3671.7
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
400 divided by 78 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3671.705
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.

Moving on to step 10:
78 can be fit into 100 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 3671.7051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
If we divide 220 by 78, we get 2 and a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 3671.70512
Deduct 156 from 220 and we're left 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:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 3671.705128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
160 divided by 78 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 3671.7051282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3671.7051282
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 3671.7051282 with a remaining 4e-08.
