We look at the division of 210632 by 78 
We want to divide 210632 by 78.

Advancing to step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 78

Moving on to step 2:
The number 78 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 78

On to step 3:
78 can be fit into 210 2 times, resulting in a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 54 after subtracting 156 from 210.
Take the next digit (6) from the dividend and append it to 54, then repeat: 546 / 78

On to step 4:
If we divide 546 by 78, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 546 away from 546, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 78

Advancing to step 5:
The number 78 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 270.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 78

Moving on to step 6:
The number 78 fits into 32 0 times, leaving a remainder of 32.
The next digit of our result is 0. 
Result so far: 2700.0
If we take 0 away from 32, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
If we divide 320 by 78, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 2700.4
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
If we divide 80 by 78, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 2700.41
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
78 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2700.41
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
78 goes into 200 2 times with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 2700.4102
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
440 divided by 78 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 2700.41025
Subtracting 390 from 440 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 2700.410256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
The number 78 fits into 320 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 2700.4102564
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
78 goes into 80 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 2700.41025641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 2700.41025641, with a leftover of 2e-09.
