We look at the division of 64390849 by 408 
We want to divide 64390849 by 408.

Let's proceed to step 1:
When dividing 6 by 408, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 408

Let's proceed to step 2:
64 divided by 408 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 408

Moving on to step 3:
The number 408 fits into 643 1 times, leaving a remainder of 235.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 408 from 643 to get 235.
Grab the next digit (9) from the dividend, add it to 235, then carry on: 2359 / 408

Moving on to step 4:
2359 divided by 408 is 5 with a remainder of 319.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2040 from 2359 and we're left with 319.
Include the next digit (0) from the dividend after 319, then repeat: 3190 / 408

On to step 5:
The number 408 fits into 3190 7 times, leaving a remainder of 334.
Write down 7 as next digit of the result. 
Result so far: 157.0
The remainder is 334 after subtracting 2856 from 3190.
Grab the next digit (8) from the dividend, add it to 334, then carry on: 3348 / 408

On to step 6:
If we divide 3348 by 408, we get 8 and a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 1578.0
Subtract 3264 from 3348 to get 84.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 408

Advancing to step 7:
844 divided by 408 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 15782.0
Subtract 816 from 844 to get 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 408

On to step 8:
408 can be fit into 289 0 times, resulting in a remainder of 289.
The number 0 becomes the next digit in our result. 
Result so far: 157820.0
If we subtract 0 from 289, we get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 9:
408 goes into 2890 7 times with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 157820.7
If we subtract 2856 from 2890, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
408 goes into 340 0 times with a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 157820.7
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 11:
3400 divided by 408 is 8 with a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 157820.708
Subtract 3264 from 3400 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
When dividing 1360 by 408, we get 3 with a remainder of 136.
Put 3 as the next digit of the answer. 
Result so far: 157820.7083
The remainder is 136 after subtracting 1224 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 13:
If we divide 1360 by 408, we get 3 and a remainder of 136.
Record the quotient 3 as the next digit in the result. 
Result so far: 157820.70833
Subtract 1224 from 1360 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Our division results in 157820.70833 with a remaining 0.000136.
