We look at the division of 854638 by 83 
We're looking to find how many times 83 goes into 854638.

Step 1:
8 divided by 83 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 83

Advancing to step 2:
83 goes into 85 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 83 from 85, we get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 83

On to step 3:
If we divide 24 by 83, we get 0 and a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 24 and we're left with 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 83

Going ahead to step 4:
When dividing 246 by 83, we get 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 102.0
Deduct 166 from 246 and we're left with 80.
Include the next digit (3) from the dividend after 80, then repeat: 803 / 83

Moving on to step 5:
803 divided by 83 is 9 with a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 1029.0
The remainder is 56 after subtracting 747 from 803.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 83

Step 6:
When dividing 568 by 83, we get 6 with a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 10296.0
Subtract 498 from 568 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
83 goes into 700 8 times with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 10296.8
Deduct 664 from 700 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
If we divide 360 by 83, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 10296.84
If we take 332 away from 360, we end up 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.

On to step 9:
83 goes into 280 3 times with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 10296.843
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.

Going ahead to step 10:
The number 83 fits into 310 3 times, leaving a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 10296.8433
If we take 249 away from 310, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final result is 10296.8433 with a remainder of 0.00061.
