85015853 ÷ 666 
We want to figure out the number of times 85015853 can be divided by 666.

On to step 1:
When dividing 8 by 666, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 666

Let's proceed to step 2:
When dividing 85 by 666, we get 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Bring next digit (0) of the dividend behind the 85 and repeat the process: 850 / 666

On to step 3:
850 divided by 666 is 1 with a remainder of 184.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 666 from 850 and we're left with 184.
Grab the next digit (1) from the dividend, add it to 184, then carry on: 1841 / 666

Let's proceed to step 4:
666 goes into 1841 2 times with a remainder of 509.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1332 from 1841 and we're left with 509.
Bring next digit (5) of the dividend behind the 509 and repeat the process: 5095 / 666

Going ahead to step 5:
666 can be fit into 5095 7 times, resulting in a remainder of 433.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Subtracting 4662 from 5095 leaves us with 433.
Bring next digit (8) of the dividend behind the 433 and repeat the process: 4338 / 666

Going ahead to step 6:
If we divide 4338 by 666, we get 6 and a remainder of 342.
Put 6 as the next digit of the answer. 
Result so far: 1276.0
If we take 3996 away from 4338, we end up with 342.
Grab the next digit (5) from the dividend, add it to 342, then carry on: 3425 / 666

Let's proceed to step 7:
If we divide 3425 by 666, we get 5 and a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 12765.0
Subtract 3330 from 3425 to get 95.
Grab the next digit (3) from the dividend, add it to 95, then carry on: 953 / 666

Advancing to step 8:
953 divided by 666 is 1 with a remainder of 287.
Put 1 as the next digit of the answer. 
Result so far: 127651.0
If we subtract 666 from 953, we get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Step 9:
666 can be fit into 2870 4 times, resulting in a remainder of 206.
The number 4 becomes the next digit in our result. 
Result so far: 127651.4
The remainder is 206 after subtracting 2664 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 10:
2060 divided by 666 is 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 127651.43
Subtract 1998 from 2060 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
The number 666 fits into 620 0 times, leaving a remainder of 620.
The number 0 becomes the next digit in our result. 
Result so far: 127651.43
If we subtract 0 from 620, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 12:
666 can be fit into 6200 9 times, resulting in a remainder of 206.
Use 9 as the next digit of our solution. 
Result so far: 127651.4309
Deduct 5994 from 6200 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 13:
2060 divided by 666 is 3 with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 127651.43093
If we subtract 1998 from 2060, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 14:
666 goes into 620 0 times with a remainder of 620.
Use 0 as the next digit of our solution. 
Result so far: 127651.43093
Deduct 0 from 620 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 15:
6200 divided by 666 is 9 with a remainder of 206.
Put 9 as the next digit of the answer. 
Result so far: 127651.4309309
The remainder is 206 after subtracting 5994 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 16:
666 goes into 2060 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 127651.43093093
If we subtract 1998 from 2060, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 127651.43093093, and the remainder is 6.2e-08.
