We divide 30707993 by 660
Let's see how many times 660 fits into 30707993.

On to step 1:
3 divided by 660 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 660

Advancing to step 2:
660 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 660

Step 3:
The number 660 fits into 307 0 times, leaving a remainder of 307.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 307 leaves us with 307.
Fetch the next digit (0) from the dividend, attach it to 307 and continue: 3070 / 660

Step 4:
660 can be fit into 3070 4 times, resulting in a remainder of 430.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 430 after subtracting 2640 from 3070.
Grab the next digit (7) from the dividend, add it to 430, then carry on: 4307 / 660

Step 5:
660 can be fit into 4307 6 times, resulting in a remainder of 347.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtracting 3960 from 4307 leaves us with 347.
Grab the next digit (9) from the dividend, add it to 347, then carry on: 3479 / 660

Moving on to step 6:
When dividing 3479 by 660, we get 5 with a remainder of 179.
Record the quotient 5 as the next digit in the result. 
Result so far: 465.0
If we take 3300 away from 3479, we end up with 179.
Take the next digit (9) from the dividend and append it to 179, then repeat: 1799 / 660

Advancing to step 7:
660 goes into 1799 2 times with a remainder of 479.
The number 2 becomes the next digit in our result. 
Result so far: 4652.0
Deduct 1320 from 1799 and we're left with 479.
Grab the next digit (3) from the dividend, add it to 479, then carry on: 4793 / 660

Let's proceed to step 8:
660 goes into 4793 7 times with a remainder of 173.
Record the quotient 7 as the next digit in the result. 
Result so far: 46527.0
If we subtract 4620 from 4793, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 9:
660 can be fit into 1730 2 times, resulting in a remainder of 410.
Put 2 as the next digit of the answer. 
Result so far: 46527.2
The remainder is 410 after subtracting 1320 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 10:
4100 divided by 660 is 6 with a remainder of 140.
The next digit of our result is 6. 
Result so far: 46527.26
The remainder is 140 after subtracting 3960 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
660 goes into 1400 2 times with a remainder of 80.
The next digit of our result is 2. 
Result so far: 46527.262
If we subtract 1320 from 1400, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
If we divide 800 by 660, we get 1 and a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 46527.2621
If we take 660 away from 800, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
When dividing 1400 by 660, we get 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 46527.26212
If we take 1320 away from 1400, we end up 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 14:
660 goes into 800 1 times with a remainder of 140.
Write down 1 as next digit of the result. 
Result so far: 46527.262121
Subtract 660 from 800 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 15:
When dividing 1400 by 660, we get 2 with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 46527.2621212
Deduct 1320 from 1400 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.

Moving on to step 16:
The number 660 fits into 800 1 times, leaving a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 46527.26212121
The remainder is 140 after subtracting 660 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 46527.26212121 with a remainder of 1.4e-07.
