We divide 39727259 by 646
The aim is to understand the frequency of 646 in 39727259.

Advancing to step 1:
646 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 646

Going ahead to step 2:
646 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 646

On to step 3:
646 goes into 397 0 times with a remainder of 397.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 397 and we're left with 397.
Grab the next digit (2) from the dividend, add it to 397, then carry on: 3972 / 646

Going ahead to step 4:
When dividing 3972 by 646, we get 6 with a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 3876 from 3972 leaves us with 96.
Bring next digit (7) of the dividend behind the 96 and repeat the process: 967 / 646

Step 5:
967 divided by 646 is 1 with a remainder of 321.
Write down 1 as next digit of the result. 
Result so far: 61.0
Deduct 646 from 967 and we're left with 321.
Grab the next digit (2) from the dividend, add it to 321, then carry on: 3212 / 646

Going ahead to step 6:
646 goes into 3212 4 times with a remainder of 628.
The number 4 becomes the next digit in our result. 
Result so far: 614.0
Deduct 2584 from 3212 and we're left with 628.
Include the next digit (5) from the dividend after 628, then repeat: 6285 / 646

Moving on to step 7:
646 can be fit into 6285 9 times, resulting in a remainder of 471.
Put 9 as the next digit of the answer. 
Result so far: 6149.0
If we take 5814 away from 6285, we end up with 471.
Append the next digit (9) from the dividend to 471 and continue with: 4719 / 646

Moving on to step 8:
4719 divided by 646 is 7 with a remainder of 197.
Put 7 as the next digit of the answer. 
Result so far: 61497.0
If we subtract 4522 from 4719, we get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 9:
1970 divided by 646 is 3 with a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 61497.3
Subtracting 1938 from 1970 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
The number 646 fits into 320 0 times, leaving a remainder of 320.
The next digit of our result is 0. 
Result so far: 61497.3
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 11:
The number 646 fits into 3200 4 times, leaving a remainder of 616.
Record the quotient 4 as the next digit in the result. 
Result so far: 61497.304
Subtracting 2584 from 3200 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 12:
When dividing 6160 by 646, we get 9 with a remainder of 346.
The next digit of our result is 9. 
Result so far: 61497.3049
Subtract 5814 from 6160 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 13:
If we divide 3460 by 646, we get 5 and a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 61497.30495
The remainder is 230 after subtracting 3230 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 14:
The number 646 fits into 2300 3 times, leaving a remainder of 362.
The next digit of our result is 3. 
Result so far: 61497.304953
Subtracting 1938 from 2300 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 15:
3620 divided by 646 is 5 with a remainder of 390.
Use 5 as the next digit of our solution. 
Result so far: 61497.3049535
Subtracting 3230 from 3620 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 16:
646 can be fit into 3900 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 61497.30495356
Subtracting 3876 from 3900 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 61497.30495356 with a remaining 2.4e-08.
