13715703 divided by 646 
Let's see how many times 646 fits into 13715703.

Going ahead to step 1:
When dividing 1 by 646, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 646

Moving on to step 2:
646 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 646

Step 3:
646 goes into 137 0 times with a remainder of 137.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 137 after subtracting 0 from 137.
Append the next digit (1) from the dividend to 137 and continue with: 1371 / 646

Step 4:
The number 646 fits into 1371 2 times, leaving a remainder of 79.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1292 from 1371 and we're left with 79.
Append the next digit (5) from the dividend to 79 and continue with: 795 / 646

On to step 5:
646 goes into 795 1 times with a remainder of 149.
The next digit of our result is 1. 
Result so far: 21.0
If we take 646 away from 795, we end up with 149.
Fetch the next digit (7) from the dividend, attach it to 149 and continue: 1497 / 646

On to step 6:
1497 divided by 646 is 2 with a remainder of 205.
The number 2 becomes the next digit in our result. 
Result so far: 212.0
Deduct 1292 from 1497 and we're left with 205.
Fetch the next digit (0) from the dividend, attach it to 205 and continue: 2050 / 646

Step 7:
The number 646 fits into 2050 3 times, leaving a remainder of 112.
The number 3 becomes the next digit in our result. 
Result so far: 2123.0
If we subtract 1938 from 2050, we get 112.
Fetch the next digit (3) from the dividend, attach it to 112 and continue: 1123 / 646

On to step 8:
646 goes into 1123 1 times with a remainder of 477.
Record the quotient 1 as the next digit in the result. 
Result so far: 21231.0
Deduct 646 from 1123 and we're left with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Advancing to step 9:
646 can be fit into 4770 7 times, resulting in a remainder of 248.
The next digit of our result is 7. 
Result so far: 21231.7
The remainder is 248 after subtracting 4522 from 4770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 10:
The number 646 fits into 2480 3 times, leaving a remainder of 542.
Record the quotient 3 as the next digit in the result. 
Result so far: 21231.73
If we take 1938 away from 2480, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Let's proceed to step 11:
When dividing 5420 by 646, we get 8 with a remainder of 252.
The number 8 becomes the next digit in our result. 
Result so far: 21231.738
If we take 5168 away from 5420, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 12:
If we divide 2520 by 646, we get 3 and a remainder of 582.
The next digit of our result is 3. 
Result so far: 21231.7383
Deduct 1938 from 2520 and we're left with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Let's proceed to step 13:
When dividing 5820 by 646, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 21231.73839
If we subtract 5814 from 5820, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
The number 646 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 21231.73839
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
600 divided by 646 is 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 21231.73839
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 21231.73839 with a remaining 6e-06.
