85472323 ÷ 660 
We're looking to find how many times 660 goes into 85472323.

On to step 1:
When dividing 8 by 660, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 660

Advancing to step 2:
If we divide 85 by 660, we get 0 and a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Bring next digit (4) of the dividend behind the 85 and repeat the process: 854 / 660

Step 3:
The number 660 fits into 854 1 times, leaving a remainder of 194.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 660 from 854, we get 194.
Fetch the next digit (7) from the dividend, attach it to 194 and continue: 1947 / 660

Let's proceed to step 4:
If we divide 1947 by 660, we get 2 and a remainder of 627.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1320 from 1947 and we're left with 627.
Include the next digit (2) from the dividend after 627, then repeat: 6272 / 660

On to step 5:
6272 divided by 660 is 9 with a remainder of 332.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
If we subtract 5940 from 6272, we get 332.
Fetch the next digit (3) from the dividend, attach it to 332 and continue: 3323 / 660

Moving on to step 6:
660 goes into 3323 5 times with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 1295.0
Subtract 3300 from 3323 to get 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 660

Advancing to step 7:
The number 660 fits into 232 0 times, leaving a remainder of 232.
Record the quotient 0 as the next digit in the result. 
Result so far: 12950.0
The remainder is 232 after subtracting 0 from 232.
Append the next digit (3) from the dividend to 232 and continue with: 2323 / 660

Let's proceed to step 8:
The number 660 fits into 2323 3 times, leaving a remainder of 343.
The next digit of our result is 3. 
Result so far: 129503.0
Deduct 1980 from 2323 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 9:
If we divide 3430 by 660, we get 5 and a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 129503.5
If we subtract 3300 from 3430, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
When dividing 1300 by 660, we get 1 with a remainder of 640.
Use 1 as the next digit of our solution. 
Result so far: 129503.51
Subtract 660 from 1300 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 11:
If we divide 6400 by 660, we get 9 and a remainder of 460.
The next digit of our result is 9. 
Result so far: 129503.519
If we take 5940 away from 6400, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 12:
4600 divided by 660 is 6 with a remainder of 640.
Write down 6 as next digit of the result. 
Result so far: 129503.5196
If we take 3960 away from 4600, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 13:
If we divide 6400 by 660, we get 9 and a remainder of 460.
Put 9 as the next digit of the answer. 
Result so far: 129503.51969
Subtracting 5940 from 6400 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 14:
When dividing 4600 by 660, we get 6 with a remainder of 640.
Put 6 as the next digit of the answer. 
Result so far: 129503.519696
Deduct 3960 from 4600 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 15:
6400 divided by 660 is 9 with a remainder of 460.
Record the quotient 9 as the next digit in the result. 
Result so far: 129503.5196969
Subtract 5940 from 6400 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 16:
If we divide 4600 by 660, we get 6 and a remainder of 640.
Record the quotient 6 as the next digit in the result. 
Result so far: 129503.51969696
Subtracting 3960 from 4600 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

After the division, we end up with 129503.51969696 and a remainder of 6.4e-07.
