Let's divide 19851 by 71
Our goal is to divide 19851 by 71.

Going ahead to step 1:
1 divided by 71 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 71

Step 2:
71 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 71

Let's proceed to step 3:
When dividing 198 by 71, we get 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 142 from 198 and we're left with 56.
Fetch the next digit (5) from the dividend, attach it to 56 and continue: 565 / 71

Step 4:
The number 71 fits into 565 7 times, leaving a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtract 497 from 565 to get 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 71

Advancing to step 5:
When dividing 681 by 71, we get 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 279.0
Deduct 639 from 681 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 6:
71 goes into 420 5 times with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 279.5
Subtracting 355 from 420 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 7:
When dividing 650 by 71, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 279.59
The remainder is 11 after subtracting 639 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
71 goes into 110 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 279.591
Subtract 71 from 110 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
71 can be fit into 390 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 279.5915
Subtracting 355 from 390 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
If we divide 350 by 71, we get 4 and a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 279.59154
Deduct 284 from 350 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 11:
If we divide 660 by 71, we get 9 and a remainder of 21.
The next digit of our result is 9. 
Result so far: 279.591549
If we take 639 away from 660, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 12:
210 divided by 71 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 279.5915492
If we subtract 142 from 210, 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.

Advancing to step 13:
71 goes into 680 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 279.59154929
The remainder is 41 after subtracting 639 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

In conclusion, the division gives 279.59154929 with a balance of 4.1e-08.
