We're dividing 852090 by 83 
Let's see how many times 83 fits into 852090.

Going ahead to step 1:
When dividing 8 by 83, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 83

Advancing to step 2:
83 goes into 85 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 83 from 85 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 83

On to step 3:
If we divide 22 by 83, we get 0 and a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 22 leaves us with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 83

Advancing to step 4:
If we divide 220 by 83, we get 2 and a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 54 after subtracting 166 from 220.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 83

On to step 5:
83 goes into 549 6 times with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 1026.0
Deduct 498 from 549 and we're left with 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 83

Going ahead to step 6:
83 can be fit into 510 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 10266.0
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 7:
When dividing 120 by 83, we get 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 10266.1
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.

Step 8:
370 divided by 83 is 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 10266.14
If we take 332 away from 370, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
380 divided by 83 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 10266.144
Subtract 332 from 380 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 10266.144, with a leftover of 0.0048.
