We look at the division of 258521 by 83 
Our goal is to divide 258521 by 83.

Going ahead to step 1:
When dividing 2 by 83, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 83

Advancing to step 2:
83 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 83

Moving on to step 3:
When dividing 258 by 83, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 249 from 258 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 83

Advancing to step 4:
The number 83 fits into 95 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 83 from 95 leaves us with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 83

Let's proceed to step 5:
If we divide 122 by 83, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 311.0
Subtracting 83 from 122 leaves us with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 83

Step 6:
83 can be fit into 391 4 times, resulting in a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 3114.0
Subtract 332 from 391 to 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.

Advancing to step 7:
If we divide 590 by 83, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 3114.7
If we take 581 away from 590, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
If we divide 90 by 83, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 3114.71
Deduct 83 from 90 and we're left 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.

Let's proceed to step 9:
The number 83 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 3114.71
If we take 0 away from 70, we end up 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.

Advancing to step 10:
83 goes into 700 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 3114.7108
Subtract 664 from 700 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
If we divide 360 by 83, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 3114.71084
Subtracting 332 from 360 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
83 goes into 280 3 times with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 3114.710843
If we subtract 249 from 280, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
The number 83 fits into 310 3 times, leaving a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 3114.7108433
The remainder is 61 after subtracting 249 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 3114.7108433 with a remaining 6.1e-07.
