Let's divide 663430 by 83
We want to figure out the number of times 663430 can be divided by 83.

Let's proceed to step 1:
When dividing 6 by 83, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 83

On to step 2:
83 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 83

Going ahead to step 3:
83 goes into 663 7 times with a remainder of 82.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 581 from 663 to get 82.
Include the next digit (4) from the dividend after 82, then repeat: 824 / 83

Let's proceed to step 4:
83 goes into 824 9 times with a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Deduct 747 from 824 and we're left with 77.
Fetch the next digit (3) from the dividend, attach it to 77 and continue: 773 / 83

Going ahead to step 5:
773 divided by 83 is 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 799.0
The remainder is 26 after subtracting 747 from 773.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 83

Going ahead to step 6:
83 can be fit into 260 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 7993.0
If we subtract 249 from 260, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 83, we get 1 and a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 7993.1
If we subtract 83 from 110, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 8:
The number 83 fits into 270 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 7993.13
The remainder is 21 after subtracting 249 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
210 divided by 83 is 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 7993.132
If we take 166 away from 210, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
When dividing 440 by 83, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 7993.1325
If we subtract 415 from 440, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
When dividing 250 by 83, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 7993.13253
If we take 249 away from 250, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
10 divided by 83 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7993.13253
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
100 divided by 83 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 7993.1325301
Subtract 83 from 100 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 14:
When dividing 170 by 83, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 7993.13253012
The remainder is 4 after subtracting 166 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 7993.13253012 with a balance of 4e-09.
