7321856 ÷ 660 
We want to figure out the number of times 7321856 can be divided by 660.

On to step 1:
7 divided by 660 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 660

Advancing to step 2:
660 can be fit into 73 0 times, resulting in a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Take the next digit (2) from the dividend and append it to 73, then repeat: 732 / 660

Going ahead to step 3:
The number 660 fits into 732 1 times, leaving a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 660 from 732 and we're left with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 660

Step 4:
660 goes into 721 1 times with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 660 from 721, we get 61.
Grab the next digit (8) from the dividend, add it to 61, then carry on: 618 / 660

Moving on to step 5:
When dividing 618 by 660, we get 0 with a remainder of 618.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Subtract 0 from 618 to get 618.
Append the next digit (5) from the dividend to 618 and continue with: 6185 / 660

Let's proceed to step 6:
If we divide 6185 by 660, we get 9 and a remainder of 245.
Use 9 as the next digit of our solution. 
Result so far: 1109.0
If we take 5940 away from 6185, we end up with 245.
Append the next digit (6) from the dividend to 245 and continue with: 2456 / 660

On to step 7:
When dividing 2456 by 660, we get 3 with a remainder of 476.
Put 3 as the next digit of the answer. 
Result so far: 11093.0
Subtracting 1980 from 2456 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 8:
4760 divided by 660 is 7 with a remainder of 140.
Put 7 as the next digit of the answer. 
Result so far: 11093.7
If we subtract 4620 from 4760, we 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.

Moving on to step 9:
The number 660 fits into 1400 2 times, leaving a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 11093.72
Subtracting 1320 from 1400 leaves us 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.

Let's proceed to step 10:
If we divide 800 by 660, we get 1 and a remainder of 140.
The number 1 becomes the next digit in our result. 
Result so far: 11093.721
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.

Going ahead to step 11:
If we divide 1400 by 660, we get 2 and a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 11093.7212
Subtracting 1320 from 1400 leaves us 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.

On to step 12:
660 can be fit into 800 1 times, resulting in a remainder of 140.
The next digit of our result is 1. 
Result so far: 11093.72121
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.

Moving on to step 13:
1400 divided by 660 is 2 with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 11093.721212
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.

Let's proceed to step 14:
800 divided by 660 is 1 with a remainder of 140.
The next digit of our result is 1. 
Result so far: 11093.7212121
Deduct 660 from 800 and we're left 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.

Step 15:
660 goes into 1400 2 times with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 11093.72121212
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.

Our division results in 11093.72121212 with a remaining 8e-08.
