We're dividing 16477261 by 646 
Let's see how many times 646 fits into 16477261.

Let's proceed to step 1:
The number 646 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 646

Let's proceed to step 2:
When dividing 16 by 646, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 646

On to step 3:
646 can be fit into 164 0 times, resulting in a remainder of 164.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 164, we end up with 164.
Take the next digit (7) from the dividend and append it to 164, then repeat: 1647 / 646

Advancing to step 4:
The number 646 fits into 1647 2 times, leaving a remainder of 355.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1292 away from 1647, we end up with 355.
Append the next digit (7) from the dividend to 355 and continue with: 3557 / 646

Step 5:
When dividing 3557 by 646, we get 5 with a remainder of 327.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 3230 from 3557 leaves us with 327.
Fetch the next digit (2) from the dividend, attach it to 327 and continue: 3272 / 646

Let's proceed to step 6:
646 can be fit into 3272 5 times, resulting in a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 255.0
Subtracting 3230 from 3272 leaves us with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 646

On to step 7:
426 divided by 646 is 0 with a remainder of 426.
Put 0 as the next digit of the answer. 
Result so far: 2550.0
If we take 0 away from 426, we end up with 426.
Grab the next digit (1) from the dividend, add it to 426, then carry on: 4261 / 646

On to step 8:
If we divide 4261 by 646, we get 6 and a remainder of 385.
Record the quotient 6 as the next digit in the result. 
Result so far: 25506.0
Subtract 3876 from 4261 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 9:
When dividing 3850 by 646, we get 5 with a remainder of 620.
The number 5 becomes the next digit in our result. 
Result so far: 25506.5
If we subtract 3230 from 3850, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 10:
The number 646 fits into 6200 9 times, leaving a remainder of 386.
Use 9 as the next digit of our solution. 
Result so far: 25506.59
Deduct 5814 from 6200 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 11:
When dividing 3860 by 646, we get 5 with a remainder of 630.
The next digit of our result is 5. 
Result so far: 25506.595
The remainder is 630 after subtracting 3230 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 12:
If we divide 6300 by 646, we get 9 and a remainder of 486.
Write down 9 as next digit of the result. 
Result so far: 25506.5959
Deduct 5814 from 6300 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 13:
646 can be fit into 4860 7 times, resulting in a remainder of 338.
Put 7 as the next digit of the answer. 
Result so far: 25506.59597
Deduct 4522 from 4860 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 14:
646 can be fit into 3380 5 times, resulting in a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 25506.595975
Subtract 3230 from 3380 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 15:
646 can be fit into 1500 2 times, resulting in a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 25506.5959752
The remainder is 208 after subtracting 1292 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 16:
If we divide 2080 by 646, we get 3 and a remainder of 142.
Record the quotient 3 as the next digit in the result. 
Result so far: 25506.59597523
The remainder is 142 after subtracting 1938 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Our division results in 25506.59597523 with a remaining 1.42e-07.
