55708099 divided by 660 
Let's see how many times 660 fits into 55708099.

Step 1:
660 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 660

Advancing to step 2:
660 can be fit into 55 0 times, resulting in a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 660

Step 3:
The number 660 fits into 557 0 times, leaving a remainder of 557.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 557, we get 557.
Take the next digit (0) from the dividend and append it to 557, then repeat: 5570 / 660

Step 4:
660 goes into 5570 8 times with a remainder of 290.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 5280 away from 5570, we end up with 290.
Include the next digit (8) from the dividend after 290, then repeat: 2908 / 660

Going ahead to step 5:
If we divide 2908 by 660, we get 4 and a remainder of 268.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Deduct 2640 from 2908 and we're left with 268.
Fetch the next digit (0) from the dividend, attach it to 268 and continue: 2680 / 660

Let's proceed to step 6:
If we divide 2680 by 660, we get 4 and a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 844.0
Subtracting 2640 from 2680 leaves us with 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 660

Advancing to step 7:
The number 660 fits into 409 0 times, leaving a remainder of 409.
The next digit of our result is 0. 
Result so far: 8440.0
The remainder is 409 after subtracting 0 from 409.
Fetch the next digit (9) from the dividend, attach it to 409 and continue: 4099 / 660

Moving on to step 8:
When dividing 4099 by 660, we get 6 with a remainder of 139.
The number 6 becomes the next digit in our result. 
Result so far: 84406.0
The remainder is 139 after subtracting 3960 from 4099.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 9:
1390 divided by 660 is 2 with a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 84406.2
If we subtract 1320 from 1390, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
660 goes into 700 1 times with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 84406.21
If we subtract 660 from 700, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
The number 660 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 84406.21
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 12:
660 goes into 4000 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 84406.2106
Deduct 3960 from 4000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
660 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 84406.2106
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 14:
When dividing 4000 by 660, we get 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 84406.210606
The remainder is 40 after subtracting 3960 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
The number 660 fits into 400 0 times, leaving a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 84406.210606
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 16:
660 can be fit into 4000 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 84406.21060606
If we subtract 3960 from 4000, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 84406.21060606, with a leftover of 4e-08.
