80487562 ÷ 664 
We want to figure out the number of times 80487562 can be divided by 664.

Going ahead to step 1:
If we divide 8 by 664, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 664

Advancing to step 2:
80 divided by 664 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 664

On to step 3:
664 can be fit into 804 1 times, resulting in a remainder of 140.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 664 from 804 and we're left with 140.
Take the next digit (8) from the dividend and append it to 140, then repeat: 1408 / 664

Going ahead to step 4:
If we divide 1408 by 664, we get 2 and a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1328 from 1408, we get 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 664

On to step 5:
If we divide 807 by 664, we get 1 and a remainder of 143.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtract 664 from 807 to get 143.
Fetch the next digit (5) from the dividend, attach it to 143 and continue: 1435 / 664

Moving on to step 6:
664 goes into 1435 2 times with a remainder of 107.
The next digit of our result is 2. 
Result so far: 1212.0
Subtracting 1328 from 1435 leaves us with 107.
Fetch the next digit (6) from the dividend, attach it to 107 and continue: 1076 / 664

Advancing to step 7:
664 can be fit into 1076 1 times, resulting in a remainder of 412.
Write down 1 as next digit of the result. 
Result so far: 12121.0
If we take 664 away from 1076, we end up with 412.
Fetch the next digit (2) from the dividend, attach it to 412 and continue: 4122 / 664

Moving on to step 8:
664 goes into 4122 6 times with a remainder of 138.
Record the quotient 6 as the next digit in the result. 
Result so far: 121216.0
The remainder is 138 after subtracting 3984 from 4122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 9:
1380 divided by 664 is 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 121216.2
If we take 1328 away from 1380, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
When dividing 520 by 664, we get 0 with a remainder of 520.
The next digit of our result is 0. 
Result so far: 121216.2
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 11:
When dividing 5200 by 664, we get 7 with a remainder of 552.
Put 7 as the next digit of the answer. 
Result so far: 121216.207
The remainder is 552 after subtracting 4648 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 12:
If we divide 5520 by 664, we get 8 and a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 121216.2078
If we take 5312 away from 5520, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 13:
If we divide 2080 by 664, we get 3 and a remainder of 88.
Write down 3 as next digit of the result. 
Result so far: 121216.20783
Subtract 1992 from 2080 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 14:
880 divided by 664 is 1 with a remainder of 216.
The next digit of our result is 1. 
Result so far: 121216.207831
Deduct 664 from 880 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 15:
When dividing 2160 by 664, we get 3 with a remainder of 168.
Write down 3 as next digit of the result. 
Result so far: 121216.2078313
Subtracting 1992 from 2160 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 16:
664 goes into 1680 2 times with a remainder of 352.
Put 2 as the next digit of the answer. 
Result so far: 121216.20783132
The remainder is 352 after subtracting 1328 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The quotient of the division is 121216.20783132, and the remainder is 3.52e-07.
