We divide 664138 by 5
We want to divide 664138 by 5.

Step 1:
The number 5 fits into 6 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 5 from 6, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 5

Step 2:
16 divided by 5 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 15 from 16 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 5

On to step 3:
5 can be fit into 14 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Deduct 10 from 14 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 5

Step 4:
If we divide 41 by 5, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 1328.0
The remainder is 1 after subtracting 40 from 41.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 5

Going ahead to step 5:
13 divided by 5 is 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 13282.0
The remainder is 3 after subtracting 10 from 13.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 5

Advancing to step 6:
5 can be fit into 38 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 132827.0
If we take 35 away from 38, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 5, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 132827.6
Subtracting 30 from 30 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 132827.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 5 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 132827.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 132827.6 with a remainder of 0.0.
