We're dividing 65607609 by 438 
We want to divide 65607609 by 438.

Let's proceed to step 1:
The number 438 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 438

Step 2:
When dividing 65 by 438, we get 0 with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Take the next digit (6) from the dividend and append it to 65, then repeat: 656 / 438

Going ahead to step 3:
The number 438 fits into 656 1 times, leaving a remainder of 218.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 438 from 656 leaves us with 218.
Grab the next digit (0) from the dividend, add it to 218, then carry on: 2180 / 438

On to step 4:
438 goes into 2180 4 times with a remainder of 428.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 1752 from 2180 to get 428.
Include the next digit (7) from the dividend after 428, then repeat: 4287 / 438

On to step 5:
4287 divided by 438 is 9 with a remainder of 345.
Write down 9 as next digit of the result. 
Result so far: 149.0
Deduct 3942 from 4287 and we're left with 345.
Include the next digit (6) from the dividend after 345, then repeat: 3456 / 438

Step 6:
438 goes into 3456 7 times with a remainder of 390.
Use 7 as the next digit of our solution. 
Result so far: 1497.0
If we subtract 3066 from 3456, we get 390.
Append the next digit (0) from the dividend to 390 and continue with: 3900 / 438

Let's proceed to step 7:
When dividing 3900 by 438, we get 8 with a remainder of 396.
The number 8 becomes the next digit in our result. 
Result so far: 14978.0
Subtract 3504 from 3900 to get 396.
Fetch the next digit (9) from the dividend, attach it to 396 and continue: 3969 / 438

Going ahead to step 8:
When dividing 3969 by 438, we get 9 with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 149789.0
The remainder is 27 after subtracting 3942 from 3969.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
When dividing 270 by 438, we get 0 with a remainder of 270.
The next digit of our result is 0. 
Result so far: 149789.0
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
438 can be fit into 2700 6 times, resulting in a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 149789.06
Subtracting 2628 from 2700 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
If we divide 720 by 438, we get 1 and a remainder of 282.
Put 1 as the next digit of the answer. 
Result so far: 149789.061
The remainder is 282 after subtracting 438 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 12:
When dividing 2820 by 438, we get 6 with a remainder of 192.
Write down 6 as next digit of the result. 
Result so far: 149789.0616
If we subtract 2628 from 2820, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 13:
1920 divided by 438 is 4 with a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 149789.06164
Subtract 1752 from 1920 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 14:
1680 divided by 438 is 3 with a remainder of 366.
Put 3 as the next digit of the answer. 
Result so far: 149789.061643
Subtracting 1314 from 1680 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 15:
The number 438 fits into 3660 8 times, leaving a remainder of 156.
Use 8 as the next digit of our solution. 
Result so far: 149789.0616438
If we subtract 3504 from 3660, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 16:
438 can be fit into 1560 3 times, resulting in a remainder of 246.
Use 3 as the next digit of our solution. 
Result so far: 149789.06164383
Subtracting 1314 from 1560 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

The final outcome is 149789.06164383, with a leftover of 2.46e-07.
