Let's divide 20686984 by 71
We want to divide 20686984 by 71.

On to step 1:
2 divided by 71 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 71

Advancing to step 2:
71 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 71

On to step 3:
206 divided by 71 is 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 142 from 206, we get 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 71

Advancing to step 4:
The number 71 fits into 648 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 639 from 648 leaves us with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 71

Advancing to step 5:
When dividing 96 by 71, we get 1 with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 291.0
If we take 71 away from 96, we end up with 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 71

Advancing to step 6:
71 can be fit into 259 3 times, resulting in a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 2913.0
Deduct 213 from 259 and we're left with 46.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 71

Moving on to step 7:
468 divided by 71 is 6 with a remainder of 42.
The next digit of our result is 6. 
Result so far: 29136.0
Subtract 426 from 468 to get 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 71

Step 8:
424 divided by 71 is 5 with a remainder of 69.
Put 5 as the next digit of the answer. 
Result so far: 291365.0
Deduct 355 from 424 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
When dividing 690 by 71, we get 9 with a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 291365.9
If we subtract 639 from 690, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 10:
If we divide 510 by 71, we get 7 and a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 291365.97
If we take 497 away from 510, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
The number 71 fits into 130 1 times, leaving a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 291365.971
If we subtract 71 from 130, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 12:
If we divide 590 by 71, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 291365.9718
Deduct 568 from 590 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
220 divided by 71 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 291365.97183
Subtracting 213 from 220 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
The number 71 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 291365.97183
Deduct 0 from 70 and we're left 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.

On to step 15:
When dividing 700 by 71, we get 9 with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 291365.9718309
Deduct 639 from 700 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 16:
When dividing 610 by 71, we get 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 291365.97183098
Subtracting 568 from 610 leaves us 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.

The final result is 291365.97183098 with a remainder of 4.2e-08.
