70302537 ÷ 660 
Let's see how many times 660 fits into 70302537.

Advancing to step 1:
660 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 660

Going ahead to step 2:
When dividing 70 by 660, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 660

Moving on to step 3:
703 divided by 660 is 1 with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 660 from 703 leaves us with 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 660

Going ahead to step 4:
When dividing 430 by 660, we get 0 with a remainder of 430.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 430 leaves us with 430.
Take the next digit (2) from the dividend and append it to 430, then repeat: 4302 / 660

Going ahead to step 5:
4302 divided by 660 is 6 with a remainder of 342.
Write down 6 as next digit of the result. 
Result so far: 106.0
Deduct 3960 from 4302 and we're left with 342.
Bring next digit (5) of the dividend behind the 342 and repeat the process: 3425 / 660

On to step 6:
When dividing 3425 by 660, we get 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 1065.0
The remainder is 125 after subtracting 3300 from 3425.
Append the next digit (3) from the dividend to 125 and continue with: 1253 / 660

On to step 7:
When dividing 1253 by 660, we get 1 with a remainder of 593.
Record the quotient 1 as the next digit in the result. 
Result so far: 10651.0
Subtracting 660 from 1253 leaves us with 593.
Fetch the next digit (7) from the dividend, attach it to 593 and continue: 5937 / 660

Let's proceed to step 8:
When dividing 5937 by 660, we get 8 with a remainder of 657.
The number 8 becomes the next digit in our result. 
Result so far: 106518.0
The remainder is 657 after subtracting 5280 from 5937.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Going ahead to step 9:
6570 divided by 660 is 9 with a remainder of 630.
Put 9 as the next digit of the answer. 
Result so far: 106518.9
If we subtract 5940 from 6570, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 10:
If we divide 6300 by 660, we get 9 and a remainder of 360.
Write down 9 as next digit of the result. 
Result so far: 106518.99
Subtract 5940 from 6300 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

In conclusion, the division gives 106518.99 with a balance of 0.36.
