159021 divided by 83 
Our goal is to divide 159021 by 83.

Let's proceed to step 1:
If we divide 1 by 83, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 83

Let's proceed to step 2:
The number 83 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 83

On to step 3:
The number 83 fits into 159 1 times, leaving a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 83 from 159 and we're left with 76.
Bring next digit (0) of the dividend behind the 76 and repeat the process: 760 / 83

Advancing to step 4:
When dividing 760 by 83, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 747 from 760 to get 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 83

Moving on to step 5:
83 can be fit into 132 1 times, resulting in a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 191.0
If we subtract 83 from 132, we get 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 83

Advancing to step 6:
When dividing 491 by 83, we get 5 with a remainder of 76.
The number 5 becomes the next digit in our result. 
Result so far: 1915.0
Subtracting 415 from 491 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 7:
When dividing 760 by 83, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 1915.9
The remainder is 13 after subtracting 747 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
83 goes into 130 1 times with a remainder of 47.
The next digit of our result is 1. 
Result so far: 1915.91
Deduct 83 from 130 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
470 divided by 83 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 1915.915
Subtracting 415 from 470 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
83 can be fit into 550 6 times, resulting in a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 1915.9156
Subtract 498 from 550 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
If we divide 520 by 83, we get 6 and a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 1915.91566
If we take 498 away from 520, we end up 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.

Our division results in 1915.91566 with a remaining 2.2e-05.
