We're dividing 213592 by 78 
We want to divide 213592 by 78.

Let's proceed to step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 78

Moving on to step 2:
21 divided by 78 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 78

On to step 3:
If we divide 213 by 78, we get 2 and a remainder of 57.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 156 from 213, we get 57.
Take the next digit (5) from the dividend and append it to 57, then repeat: 575 / 78

Step 4:
78 goes into 575 7 times with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 546 from 575 and we're left with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 78

Step 5:
The number 78 fits into 299 3 times, leaving a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 273.0
The remainder is 65 after subtracting 234 from 299.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 78

Advancing to step 6:
78 goes into 652 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 2738.0
If we subtract 624 from 652, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
If we divide 280 by 78, we get 3 and a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 2738.3
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
78 goes into 460 5 times with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 2738.35
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
78 can be fit into 700 8 times, resulting in a remainder of 76.
The next digit of our result is 8. 
Result so far: 2738.358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
78 goes into 760 9 times with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 2738.3589
If we subtract 702 from 760, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
If we divide 580 by 78, we get 7 and a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 2738.35897
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
78 goes into 340 4 times with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 2738.358974
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 2738.3589743
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 2738.35897435
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 2738.35897435 and a remainder of 7e-08.
