Let's divide 84021 by 83
Let's see how many times 83 fits into 84021.

Let's proceed to step 1:
8 divided by 83 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 83

On to step 2:
84 divided by 83 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 83 away from 84, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 83

Moving on to step 3:
83 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 83

Going ahead to step 4:
102 divided by 83 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 101.0
The remainder is 19 after subtracting 83 from 102.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 83

Going ahead to step 5:
When dividing 191 by 83, we get 2 with a remainder of 25.
The next digit of our result is 2. 
Result so far: 1012.0
If we take 166 away from 191, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 6:
When dividing 250 by 83, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 1012.3
If we take 249 away from 250, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
83 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1012.3
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
83 can be fit into 100 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1012.301
If we take 83 away from 100, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
83 goes into 170 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 1012.3012
Subtracting 166 from 170 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
83 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1012.3012
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
83 goes into 400 4 times with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 1012.301204
If we take 332 away from 400, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
The number 83 fits into 680 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 1012.3012048
If we take 664 away from 680, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
83 goes into 160 1 times with a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 1012.30120481
Subtract 83 from 160 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

In conclusion, the division gives 1012.30120481 with a balance of 7.7e-08.
