We look at the division of 63971 by 83 
We want to divide 63971 by 83.

Advancing to step 1:
83 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 83

Advancing to step 2:
If we divide 63 by 83, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 83

Step 3:
When dividing 639 by 83, we get 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 58 after subtracting 581 from 639.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 83

Advancing to step 4:
587 divided by 83 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 77.0
If we take 581 away from 587, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 83

Step 5:
The number 83 fits into 61 0 times, leaving a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 770.0
The remainder is 61 after subtracting 0 from 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 6:
83 goes into 610 7 times with a remainder of 29.
The next digit of our result is 7. 
Result so far: 770.7
Subtracting 581 from 610 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
83 can be fit into 290 3 times, resulting in a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 770.73
The remainder is 41 after subtracting 249 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 8:
When dividing 410 by 83, we get 4 with a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 770.734
Deduct 332 from 410 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
83 can be fit into 780 9 times, resulting in a remainder of 33.
The next digit of our result is 9. 
Result so far: 770.7349
Subtract 747 from 780 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 10:
330 divided by 83 is 3 with a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 770.73493
If we subtract 249 from 330, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 11:
83 goes into 810 9 times with a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 770.734939
Deduct 747 from 810 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 12:
83 goes into 630 7 times with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 770.7349397
The remainder is 49 after subtracting 581 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 13:
83 goes into 490 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 770.73493975
Deduct 415 from 490 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final result is 770.73493975 with a remainder of 7.5e-08.
