We divide 6616578 by 664
We want to figure out the number of times 6616578 can be divided by 664.

Moving on to step 1:
664 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 664

Moving on to step 2:
66 divided by 664 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 664

Advancing to step 3:
664 can be fit into 661 0 times, resulting in a remainder of 661.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 661, we end up with 661.
Fetch the next digit (6) from the dividend, attach it to 661 and continue: 6616 / 664

Step 4:
If we divide 6616 by 664, we get 9 and a remainder of 640.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 5976 from 6616 to get 640.
Fetch the next digit (5) from the dividend, attach it to 640 and continue: 6405 / 664

Let's proceed to step 5:
664 can be fit into 6405 9 times, resulting in a remainder of 429.
Put 9 as the next digit of the answer. 
Result so far: 99.0
The remainder is 429 after subtracting 5976 from 6405.
Fetch the next digit (7) from the dividend, attach it to 429 and continue: 4297 / 664

Moving on to step 6:
4297 divided by 664 is 6 with a remainder of 313.
Put 6 as the next digit of the answer. 
Result so far: 996.0
Deduct 3984 from 4297 and we're left with 313.
Append the next digit (8) from the dividend to 313 and continue with: 3138 / 664

Let's proceed to step 7:
3138 divided by 664 is 4 with a remainder of 482.
The number 4 becomes the next digit in our result. 
Result so far: 9964.0
If we take 2656 away from 3138, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 8:
If we divide 4820 by 664, we get 7 and a remainder of 172.
The number 7 becomes the next digit in our result. 
Result so far: 9964.7
If we take 4648 away from 4820, 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.

Advancing to step 9:
If we divide 1720 by 664, we get 2 and a remainder of 392.
Use 2 as the next digit of our solution. 
Result so far: 9964.72
Subtracting 1328 from 1720 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 10:
If we divide 3920 by 664, we get 5 and a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 9964.725
Deduct 3320 from 3920 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 11:
If we divide 6000 by 664, we get 9 and a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 9964.7259
Subtracting 5976 from 6000 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
240 divided by 664 is 0 with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 9964.7259
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
When dividing 2400 by 664, we get 3 with a remainder of 408.
The number 3 becomes the next digit in our result. 
Result so far: 9964.725903
If we take 1992 away from 2400, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 14:
664 goes into 4080 6 times with a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 9964.7259036
The remainder is 96 after subtracting 3984 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 15:
960 divided by 664 is 1 with a remainder of 296.
Write down 1 as next digit of the result. 
Result so far: 9964.72590361
Deduct 664 from 960 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final outcome is 9964.72590361, with a leftover of 2.96e-07.
