We divide 27150406 by 646
Our goal is to divide 27150406 by 646.

Moving on to step 1:
2 divided by 646 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 646

Step 2:
27 divided by 646 is 0 with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 646

Step 3:
The number 646 fits into 271 0 times, leaving a remainder of 271.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 271 leaves us with 271.
Append the next digit (5) from the dividend to 271 and continue with: 2715 / 646

Advancing to step 4:
646 goes into 2715 4 times with a remainder of 131.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 131 after subtracting 2584 from 2715.
Bring next digit (0) of the dividend behind the 131 and repeat the process: 1310 / 646

Going ahead to step 5:
If we divide 1310 by 646, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
The remainder is 18 after subtracting 1292 from 1310.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 646

Step 6:
If we divide 184 by 646, we get 0 and a remainder of 184.
Put 0 as the next digit of the answer. 
Result so far: 420.0
Deduct 0 from 184 and we're left with 184.
Include the next digit (0) from the dividend after 184, then repeat: 1840 / 646

Going ahead to step 7:
If we divide 1840 by 646, we get 2 and a remainder of 548.
The next digit of our result is 2. 
Result so far: 4202.0
Deduct 1292 from 1840 and we're left with 548.
Bring next digit (6) of the dividend behind the 548 and repeat the process: 5486 / 646

Step 8:
When dividing 5486 by 646, we get 8 with a remainder of 318.
Put 8 as the next digit of the answer. 
Result so far: 42028.0
If we take 5168 away from 5486, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 9:
3180 divided by 646 is 4 with a remainder of 596.
Put 4 as the next digit of the answer. 
Result so far: 42028.4
Subtracting 2584 from 3180 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 10:
646 goes into 5960 9 times with a remainder of 146.
Record the quotient 9 as the next digit in the result. 
Result so far: 42028.49
Deduct 5814 from 5960 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 11:
646 goes into 1460 2 times with a remainder of 168.
Put 2 as the next digit of the answer. 
Result so far: 42028.492
Deduct 1292 from 1460 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
The number 646 fits into 1680 2 times, leaving a remainder of 388.
Use 2 as the next digit of our solution. 
Result so far: 42028.4922
If we subtract 1292 from 1680, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The final outcome is 42028.4922, with a leftover of 0.00388.
