We look at the division of 70666 by 83 
We're looking to find how many times 83 goes into 70666.

Step 1:
When dividing 7 by 83, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 83

Going ahead to step 2:
83 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Fetch the next digit (6) from the dividend, attach it to 70 and continue: 706 / 83

Let's proceed to step 3:
706 divided by 83 is 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 664 from 706, we get 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 83

Going ahead to step 4:
83 can be fit into 426 5 times, resulting in a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtract 415 from 426 to get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 83

Moving on to step 5:
83 can be fit into 116 1 times, resulting in a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 851.0
Deduct 83 from 116 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 6:
If we divide 330 by 83, we get 3 and a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 851.3
If we subtract 249 from 330, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 7:
83 goes into 810 9 times with a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 851.39
Deduct 747 from 810 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 8:
83 can be fit into 630 7 times, resulting in a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 851.397
Subtracting 581 from 630 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
83 can be fit into 490 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 851.3975
Subtract 415 from 490 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
If we divide 750 by 83, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 851.39759
The remainder is 3 after subtracting 747 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
The number 83 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 851.39759
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
300 divided by 83 is 3 with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 851.3975903
Deduct 249 from 300 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 13:
83 can be fit into 510 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 851.39759036
Subtracting 498 from 510 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 851.39759036 with a balance of 1.2e-08.
