We look at the division of 639464 by 83 
We want to figure out the number of times 639464 can be divided by 83.

Moving on to step 1:
The number 83 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 83

Step 2:
63 divided by 83 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 83

On to step 3:
When dividing 639 by 83, we get 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 581 from 639 and we're left with 58.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 83

Let's proceed to step 4:
The number 83 fits into 584 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
The remainder is 3 after subtracting 581 from 584.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 83

Let's proceed to step 5:
The number 83 fits into 36 0 times, leaving a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 770.0
The remainder is 36 after subtracting 0 from 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 83

Moving on to step 6:
When dividing 364 by 83, we get 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7704.0
Subtract 332 from 364 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.

Let's proceed to step 7:
83 goes into 320 3 times with a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 7704.3
If we subtract 249 from 320, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 8:
If we divide 710 by 83, we get 8 and a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 7704.38
Subtract 664 from 710 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
83 goes into 460 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 7704.385
Deduct 415 from 460 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
When dividing 450 by 83, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 7704.3855
Subtract 415 from 450 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 7704.3855 and a remainder of 0.00035.
