We look at the division of 621896 by 83 
Let's see how many times 83 fits into 621896.

Step 1:
83 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 83

Moving on to step 2:
83 goes into 62 0 times with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 83

On to step 3:
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: 7.0
The remainder is 40 after subtracting 581 from 621.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 83

Step 4:
The number 83 fits into 408 4 times, leaving a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtract 332 from 408 to get 76.
Fetch the next digit (9) from the dividend, attach it to 76 and continue: 769 / 83

Let's proceed to step 5:
83 goes into 769 9 times with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 749.0
The remainder is 22 after subtracting 747 from 769.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 83

Going ahead to step 6:
83 can be fit into 226 2 times, resulting in a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 7492.0
The remainder is 60 after subtracting 166 from 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
The number 83 fits into 600 7 times, leaving a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 7492.7
The remainder is 19 after subtracting 581 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
The number 83 fits into 190 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 7492.72
Subtract 166 from 190 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
83 goes into 240 2 times with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 7492.722
Subtract 166 from 240 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 7492.722 with a remaining 0.0074.
