We look at the division of 163891 by 83 
We want to figure out the number of times 163891 can be divided by 83.

Moving on to step 1:
83 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 83

On to step 2:
If we divide 16 by 83, we get 0 and a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 83

Moving on to step 3:
When dividing 163 by 83, we get 1 with a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 83 from 163 and we're left with 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 83

Moving on to step 4:
808 divided by 83 is 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 747 from 808 and we're left with 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 83

Advancing to step 5:
When dividing 619 by 83, we get 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 197.0
Deduct 581 from 619 and we're left with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 83

Moving on to step 6:
83 goes into 381 4 times with a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 1974.0
Deduct 332 from 381 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
The number 83 fits into 490 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 1974.5
Subtract 415 from 490 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 8:
83 can be fit into 750 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 1974.59
Subtracting 747 from 750 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
If we divide 30 by 83, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1974.59
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
83 can be fit into 300 3 times, resulting in a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 1974.5903
Deduct 249 from 300 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 11:
When dividing 510 by 83, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 1974.59036
Subtracting 498 from 510 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
If we divide 120 by 83, we get 1 and a remainder of 37.
The next digit of our result is 1. 
Result so far: 1974.590361
If we take 83 away from 120, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 13:
The number 83 fits into 370 4 times, leaving a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 1974.5903614
The remainder is 38 after subtracting 332 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
If we divide 380 by 83, we get 4 and a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 1974.59036144
Subtracting 332 from 380 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 1974.59036144 with a balance of 4.8e-08.
