We look at the division of 621343 by 83 
We want to figure out the number of times 621343 can be divided by 83.

Step 1:
The number 83 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 83

Let's proceed to step 2:
62 divided by 83 is 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 83

Step 3:
If we divide 621 by 83, we get 7 and a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 581 away from 621, we end up with 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 83

On to step 4:
83 can be fit into 403 4 times, resulting in a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Subtract 332 from 403 to get 71.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 83

Moving on to step 5:
714 divided by 83 is 8 with a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 748.0
Subtract 664 from 714 to get 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 83

On to step 6:
503 divided by 83 is 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 7486.0
Subtracting 498 from 503 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
83 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 7486.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
When dividing 500 by 83, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 7486.06
Subtracting 498 from 500 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
When dividing 20 by 83, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7486.06
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
83 can be fit into 200 2 times, resulting in a remainder of 34.
The next digit of our result is 2. 
Result so far: 7486.0602
Deduct 166 from 200 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
340 divided by 83 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 7486.06024
If we take 332 away from 340, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
83 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 7486.06024
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
800 divided by 83 is 9 with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 7486.0602409
Deduct 747 from 800 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 14:
If we divide 530 by 83, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 7486.06024096
Subtract 498 from 530 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 7486.06024096, and the remainder is 3.2e-08.
