211886 ÷ 78 
We want to figure out the number of times 211886 can be divided by 78.

Advancing to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 78

Moving on to step 2:
When dividing 21 by 78, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 78

Advancing to step 3:
If we divide 211 by 78, we get 2 and a remainder of 55.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 55 after subtracting 156 from 211.
Fetch the next digit (8) from the dividend, attach it to 55 and continue: 558 / 78

Advancing to step 4:
When dividing 558 by 78, we get 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 546 away from 558, we end up with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 78

Moving on to step 5:
128 divided by 78 is 1 with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 271.0
The remainder is 50 after subtracting 78 from 128.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 78

Moving on to step 6:
The number 78 fits into 506 6 times, leaving a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 2716.0
Deduct 468 from 506 and we're left 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 7:
380 divided by 78 is 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 2716.4
Subtracting 312 from 380 leaves us 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.

Step 8:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 2716.48
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.

On to step 9:
If we divide 560 by 78, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 2716.487
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
78 goes into 140 1 times with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 2716.4871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 11:
78 goes into 620 7 times with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 2716.48717
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.

Advancing to step 12:
When dividing 740 by 78, we get 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 2716.487179
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.

Let's proceed to step 13:
If we divide 380 by 78, we get 4 and a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 2716.4871794
Subtracting 312 from 380 leaves us 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.

Let's proceed to step 14:
When dividing 680 by 78, we get 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 2716.48717948
If we take 624 away from 680, we end up 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.

In conclusion, the division gives 2716.48717948 with a balance of 5.6e-08.
