We're dividing 521861 by 83 
We want to figure out the number of times 521861 can be divided by 83.

Step 1:
83 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 83

On to step 2:
83 goes into 52 0 times with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 83

Going ahead to step 3:
When dividing 521 by 83, we get 6 with a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 23 after subtracting 498 from 521.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 83

Let's proceed to step 4:
83 can be fit into 238 2 times, resulting in a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Subtracting 166 from 238 leaves us with 72.
Grab the next digit (6) from the dividend, add it to 72, then carry on: 726 / 83

On to step 5:
726 divided by 83 is 8 with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 628.0
Subtract 664 from 726 to get 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 83

On to step 6:
If we divide 621 by 83, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 6287.0
Subtract 581 from 621 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
If we divide 400 by 83, we get 4 and a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 6287.4
Subtract 332 from 400 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
83 goes into 680 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 6287.48
Subtract 664 from 680 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
If we divide 160 by 83, we get 1 and a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 6287.481
If we subtract 83 from 160, we 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.

On to step 10:
83 can be fit into 770 9 times, resulting in a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 6287.4819
If we take 747 away from 770, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 11:
230 divided by 83 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 6287.48192
The remainder is 64 after subtracting 166 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
The number 83 fits into 640 7 times, leaving a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 6287.481927
Subtracting 581 from 640 leaves us with 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 13:
83 goes into 590 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 6287.4819277
The remainder is 9 after subtracting 581 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 6287.4819277 with a balance of 9e-08.
