We're dividing 53756688 by 666 
We want to figure out the number of times 53756688 can be divided by 666.

Going ahead to step 1:
5 divided by 666 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 666

Advancing to step 2:
When dividing 53 by 666, we get 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 666

Step 3:
666 goes into 537 0 times with a remainder of 537.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 537 and we're left with 537.
Fetch the next digit (5) from the dividend, attach it to 537 and continue: 5375 / 666

Moving on to step 4:
666 can be fit into 5375 8 times, resulting in a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 5328 from 5375 to get 47.
Append the next digit (6) from the dividend to 47 and continue with: 476 / 666

Advancing to step 5:
The number 666 fits into 476 0 times, leaving a remainder of 476.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we subtract 0 from 476, we get 476.
Grab the next digit (6) from the dividend, add it to 476, then carry on: 4766 / 666

On to step 6:
4766 divided by 666 is 7 with a remainder of 104.
Write down 7 as next digit of the result. 
Result so far: 807.0
Subtract 4662 from 4766 to get 104.
Take the next digit (8) from the dividend and append it to 104, then repeat: 1048 / 666

Let's proceed to step 7:
If we divide 1048 by 666, we get 1 and a remainder of 382.
The number 1 becomes the next digit in our result. 
Result so far: 8071.0
The remainder is 382 after subtracting 666 from 1048.
Append the next digit (8) from the dividend to 382 and continue with: 3828 / 666

Let's proceed to step 8:
666 can be fit into 3828 5 times, resulting in a remainder of 498.
Use 5 as the next digit of our solution. 
Result so far: 80715.0
If we take 3330 away from 3828, we end up with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 9:
The number 666 fits into 4980 7 times, leaving a remainder of 318.
Record the quotient 7 as the next digit in the result. 
Result so far: 80715.7
Subtract 4662 from 4980 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 10:
The number 666 fits into 3180 4 times, leaving a remainder of 516.
The number 4 becomes the next digit in our result. 
Result so far: 80715.74
Deduct 2664 from 3180 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 11:
The number 666 fits into 5160 7 times, leaving a remainder of 498.
The next digit of our result is 7. 
Result so far: 80715.747
Subtracting 4662 from 5160 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Step 12:
When dividing 4980 by 666, we get 7 with a remainder of 318.
The next digit of our result is 7. 
Result so far: 80715.7477
Deduct 4662 from 4980 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

In conclusion, the division gives 80715.7477 with a balance of 0.00318.
