We look at the division of 58756573 by 666 
We're looking to find how many times 666 goes into 58756573.

Let's proceed to step 1:
666 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 666

Advancing to step 2:
666 can be fit into 58 0 times, resulting in a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Append the next digit (7) from the dividend to 58 and continue with: 587 / 666

On to step 3:
666 can be fit into 587 0 times, resulting in a remainder of 587.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 587 after subtracting 0 from 587.
Include the next digit (5) from the dividend after 587, then repeat: 5875 / 666

Going ahead to step 4:
If we divide 5875 by 666, we get 8 and a remainder of 547.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 5328 from 5875 leaves us with 547.
Append the next digit (6) from the dividend to 547 and continue with: 5476 / 666

Moving on to step 5:
5476 divided by 666 is 8 with a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Subtract 5328 from 5476 to get 148.
Append the next digit (5) from the dividend to 148 and continue with: 1485 / 666

On to step 6:
The number 666 fits into 1485 2 times, leaving a remainder of 153.
Use 2 as the next digit of our solution. 
Result so far: 882.0
Subtracting 1332 from 1485 leaves us with 153.
Grab the next digit (7) from the dividend, add it to 153, then carry on: 1537 / 666

On to step 7:
When dividing 1537 by 666, we get 2 with a remainder of 205.
The number 2 becomes the next digit in our result. 
Result so far: 8822.0
If we take 1332 away from 1537, we end up with 205.
Take the next digit (3) from the dividend and append it to 205, then repeat: 2053 / 666

Advancing to step 8:
666 can be fit into 2053 3 times, resulting in a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 88223.0
If we take 1998 away from 2053, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
550 divided by 666 is 0 with a remainder of 550.
The number 0 becomes the next digit in our result. 
Result so far: 88223.0
If we take 0 away from 550, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 10:
666 goes into 5500 8 times with a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 88223.08
If we take 5328 away from 5500, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 11:
666 can be fit into 1720 2 times, resulting in a remainder of 388.
Record the quotient 2 as the next digit in the result. 
Result so far: 88223.082
Subtracting 1332 from 1720 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 12:
666 goes into 3880 5 times with a remainder of 550.
Use 5 as the next digit of our solution. 
Result so far: 88223.0825
The remainder is 550 after subtracting 3330 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 13:
666 can be fit into 5500 8 times, resulting in a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 88223.08258
If we subtract 5328 from 5500, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 14:
If we divide 1720 by 666, we get 2 and a remainder of 388.
Record the quotient 2 as the next digit in the result. 
Result so far: 88223.082582
The remainder is 388 after subtracting 1332 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 15:
666 can be fit into 3880 5 times, resulting in a remainder of 550.
Put 5 as the next digit of the answer. 
Result so far: 88223.0825825
Deduct 3330 from 3880 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 16:
666 can be fit into 5500 8 times, resulting in a remainder of 172.
Record the quotient 8 as the next digit in the result. 
Result so far: 88223.08258258
Deduct 5328 from 5500 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final outcome is 88223.08258258, with a leftover of 1.72e-07.
