We divide 10510410 by 646
We want to divide 10510410 by 646.

Going ahead to step 1:
646 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 646

Moving on to step 2:
If we divide 10 by 646, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 646

Moving on to step 3:
If we divide 105 by 646, we get 0 and a remainder of 105.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 105, we end up with 105.
Fetch the next digit (1) from the dividend, attach it to 105 and continue: 1051 / 646

Advancing to step 4:
If we divide 1051 by 646, we get 1 and a remainder of 405.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 646 away from 1051, we end up with 405.
Fetch the next digit (0) from the dividend, attach it to 405 and continue: 4050 / 646

On to step 5:
646 goes into 4050 6 times with a remainder of 174.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 174 after subtracting 3876 from 4050.
Take the next digit (4) from the dividend and append it to 174, then repeat: 1744 / 646

Moving on to step 6:
646 goes into 1744 2 times with a remainder of 452.
The number 2 becomes the next digit in our result. 
Result so far: 162.0
The remainder is 452 after subtracting 1292 from 1744.
Grab the next digit (1) from the dividend, add it to 452, then carry on: 4521 / 646

Going ahead to step 7:
The number 646 fits into 4521 6 times, leaving a remainder of 645.
The number 6 becomes the next digit in our result. 
Result so far: 1626.0
If we take 3876 away from 4521, we end up with 645.
Bring next digit (0) of the dividend behind the 645 and repeat the process: 6450 / 646

On to step 8:
6450 divided by 646 is 9 with a remainder of 636.
Use 9 as the next digit of our solution. 
Result so far: 16269.0
The remainder is 636 after subtracting 5814 from 6450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 9:
If we divide 6360 by 646, we get 9 and a remainder of 546.
Write down 9 as next digit of the result. 
Result so far: 16269.9
Subtracting 5814 from 6360 leaves us with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Moving on to step 10:
The number 646 fits into 5460 8 times, leaving a remainder of 292.
The next digit of our result is 8. 
Result so far: 16269.98
Deduct 5168 from 5460 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 11:
646 goes into 2920 4 times with a remainder of 336.
The next digit of our result is 4. 
Result so far: 16269.984
The remainder is 336 after subtracting 2584 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 12:
646 can be fit into 3360 5 times, resulting in a remainder of 130.
The next digit of our result is 5. 
Result so far: 16269.9845
Subtract 3230 from 3360 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 13:
When dividing 1300 by 646, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 16269.98452
Deduct 1292 from 1300 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
When dividing 80 by 646, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 16269.98452
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
800 divided by 646 is 1 with a remainder of 154.
Write down 1 as next digit of the result. 
Result so far: 16269.9845201
If we take 646 away from 800, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 16:
If we divide 1540 by 646, we get 2 and a remainder of 248.
Record the quotient 2 as the next digit in the result. 
Result so far: 16269.98452012
The remainder is 248 after subtracting 1292 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

After the division, we end up with 16269.98452012 and a remainder of 2.48e-07.
