We're dividing 210986 by 78 
Our goal is to divide 210986 by 78.

On to step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
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

Going ahead to step 2:
If we divide 21 by 78, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 78

Advancing to step 3:
78 can be fit into 210 2 times, resulting in a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 156 from 210 and we're left with 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 78

On to step 4:
When dividing 549 by 78, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtracting 546 from 549 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 78

Advancing to step 5:
The number 78 fits into 38 0 times, leaving a remainder of 38.
The next digit of our result is 0. 
Result so far: 270.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 78

Let's proceed to step 6:
386 divided by 78 is 4 with a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 2704.0
Deduct 312 from 386 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 7:
The number 78 fits into 740 9 times, leaving a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 2704.9
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
When dividing 380 by 78, we get 4 with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 2704.94
Deduct 312 from 380 and we're left 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.

Going ahead to step 9:
If we divide 680 by 78, we get 8 and a remainder of 56.
The next digit of our result is 8. 
Result so far: 2704.948
Subtract 624 from 680 to 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.

Going ahead to step 10:
If we divide 560 by 78, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 2704.9487
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
78 goes into 140 1 times with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 2704.94871
Deduct 78 from 140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 12:
78 can be fit into 620 7 times, resulting in a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 2704.948717
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 13:
740 divided by 78 is 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 2704.9487179
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
78 can be fit into 380 4 times, resulting in a remainder of 68.
The next digit of our result is 4. 
Result so far: 2704.94871794
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 2704.94871794 and a remainder of 6.8e-08.
