Let's divide 64317580 by 438
We're looking to find how many times 438 goes into 64317580.

Going ahead to step 1:
438 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 438

On to step 2:
When dividing 64 by 438, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 438

On to step 3:
If we divide 643 by 438, we get 1 and a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 205 after subtracting 438 from 643.
Fetch the next digit (1) from the dividend, attach it to 205 and continue: 2051 / 438

Going ahead to step 4:
2051 divided by 438 is 4 with a remainder of 299.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 1752 from 2051, we get 299.
Fetch the next digit (7) from the dividend, attach it to 299 and continue: 2997 / 438

Advancing to step 5:
438 goes into 2997 6 times with a remainder of 369.
Use 6 as the next digit of our solution. 
Result so far: 146.0
Subtract 2628 from 2997 to get 369.
Take the next digit (5) from the dividend and append it to 369, then repeat: 3695 / 438

Let's proceed to step 6:
438 can be fit into 3695 8 times, resulting in a remainder of 191.
Put 8 as the next digit of the answer. 
Result so far: 1468.0
The remainder is 191 after subtracting 3504 from 3695.
Append the next digit (8) from the dividend to 191 and continue with: 1918 / 438

Step 7:
If we divide 1918 by 438, we get 4 and a remainder of 166.
Write down 4 as next digit of the result. 
Result so far: 14684.0
Subtracting 1752 from 1918 leaves us with 166.
Append the next digit (0) from the dividend to 166 and continue with: 1660 / 438

Let's proceed to step 8:
438 goes into 1660 3 times with a remainder of 346.
Write down 3 as next digit of the result. 
Result so far: 146843.0
Subtracting 1314 from 1660 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 9:
If we divide 3460 by 438, we get 7 and a remainder of 394.
Use 7 as the next digit of our solution. 
Result so far: 146843.7
Subtracting 3066 from 3460 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 10:
The number 438 fits into 3940 8 times, leaving a remainder of 436.
Use 8 as the next digit of our solution. 
Result so far: 146843.78
If we subtract 3504 from 3940, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 11:
438 goes into 4360 9 times with a remainder of 418.
The number 9 becomes the next digit in our result. 
Result so far: 146843.789
The remainder is 418 after subtracting 3942 from 4360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 12:
4180 divided by 438 is 9 with a remainder of 238.
Write down 9 as next digit of the result. 
Result so far: 146843.7899
If we take 3942 away from 4180, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The quotient of the division is 146843.7899, and the remainder is 0.00238.
