55988303 ÷ 660 
We're looking to find how many times 660 goes into 55988303.

Moving on to step 1:
When dividing 5 by 660, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 660

Advancing to step 2:
When dividing 55 by 660, we get 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 660

Let's proceed to step 3:
660 can be fit into 559 0 times, resulting in a remainder of 559.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 559 after subtracting 0 from 559.
Fetch the next digit (8) from the dividend, attach it to 559 and continue: 5598 / 660

On to step 4:
If we divide 5598 by 660, we get 8 and a remainder of 318.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 318 after subtracting 5280 from 5598.
Bring next digit (8) of the dividend behind the 318 and repeat the process: 3188 / 660

Let's proceed to step 5:
When dividing 3188 by 660, we get 4 with a remainder of 548.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Deduct 2640 from 3188 and we're left with 548.
Bring next digit (3) of the dividend behind the 548 and repeat the process: 5483 / 660

Let's proceed to step 6:
660 goes into 5483 8 times with a remainder of 203.
The number 8 becomes the next digit in our result. 
Result so far: 848.0
If we take 5280 away from 5483, we end up with 203.
Fetch the next digit (0) from the dividend, attach it to 203 and continue: 2030 / 660

Let's proceed to step 7:
2030 divided by 660 is 3 with a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 8483.0
Deduct 1980 from 2030 and we're left with 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 660

Let's proceed to step 8:
The number 660 fits into 503 0 times, leaving a remainder of 503.
Use 0 as the next digit of our solution. 
Result so far: 84830.0
Deduct 0 from 503 and we're left with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

On to step 9:
The number 660 fits into 5030 7 times, leaving a remainder of 410.
The next digit of our result is 7. 
Result so far: 84830.7
If we subtract 4620 from 5030, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 10:
660 can be fit into 4100 6 times, resulting in a remainder of 140.
Use 6 as the next digit of our solution. 
Result so far: 84830.76
Subtract 3960 from 4100 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.

Step 11:
660 goes into 1400 2 times with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 84830.762
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.

Step 12:
If we divide 800 by 660, we get 1 and a remainder of 140.
Write down 1 as next digit of the result. 
Result so far: 84830.7621
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.

On to step 13:
660 can be fit into 1400 2 times, resulting in a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 84830.76212
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.

Going ahead to step 14:
660 can be fit into 800 1 times, resulting in a remainder of 140.
Use 1 as the next digit of our solution. 
Result so far: 84830.762121
If we subtract 660 from 800, 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.

Let's proceed to 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: 84830.7621212
The remainder is 80 after subtracting 1320 from 1400.
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:
When dividing 800 by 660, we get 1 with a remainder of 140.
The number 1 becomes the next digit in our result. 
Result so far: 84830.76212121
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.

After the division, we end up with 84830.76212121 and a remainder of 1.4e-07.
