We divide 65860460 by 646
The aim is to understand the frequency of 646 in 65860460.

Let's proceed to step 1:
When dividing 6 by 646, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 646

Let's proceed to step 2:
646 can be fit into 65 0 times, resulting in a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Take the next digit (8) from the dividend and append it to 65, then repeat: 658 / 646

Let's proceed to step 3:
646 goes into 658 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 646 from 658 leaves us with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 646

Let's proceed to step 4:
126 divided by 646 is 0 with a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 126, we end up with 126.
Grab the next digit (0) from the dividend, add it to 126, then carry on: 1260 / 646

Advancing to step 5:
If we divide 1260 by 646, we get 1 and a remainder of 614.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
If we subtract 646 from 1260, we get 614.
Append the next digit (4) from the dividend to 614 and continue with: 6144 / 646

On to step 6:
646 can be fit into 6144 9 times, resulting in a remainder of 330.
The next digit of our result is 9. 
Result so far: 1019.0
The remainder is 330 after subtracting 5814 from 6144.
Take the next digit (6) from the dividend and append it to 330, then repeat: 3306 / 646

On to step 7:
646 goes into 3306 5 times with a remainder of 76.
The number 5 becomes the next digit in our result. 
Result so far: 10195.0
Deduct 3230 from 3306 and we're left with 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 646

Going ahead to step 8:
760 divided by 646 is 1 with a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 101951.0
If we take 646 away from 760, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 9:
The number 646 fits into 1140 1 times, leaving a remainder of 494.
The number 1 becomes the next digit in our result. 
Result so far: 101951.1
If we take 646 away from 1140, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

On to step 10:
When dividing 4940 by 646, we get 7 with a remainder of 418.
Put 7 as the next digit of the answer. 
Result so far: 101951.17
If we subtract 4522 from 4940, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 11:
If we divide 4180 by 646, we get 6 and a remainder of 304.
The number 6 becomes the next digit in our result. 
Result so far: 101951.176
If we take 3876 away from 4180, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 12:
646 goes into 3040 4 times with a remainder of 456.
The next digit of our result is 4. 
Result so far: 101951.1764
If we subtract 2584 from 3040, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 13:
4560 divided by 646 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 101951.17647
The remainder is 38 after subtracting 4522 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
646 goes into 380 0 times with a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 101951.17647
If we subtract 0 from 380, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 15:
646 goes into 3800 5 times with a remainder of 570.
The next digit of our result is 5. 
Result so far: 101951.1764705
Subtracting 3230 from 3800 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 16:
The number 646 fits into 5700 8 times, leaving a remainder of 532.
Use 8 as the next digit of our solution. 
Result so far: 101951.17647058
If we take 5168 away from 5700, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Our division results in 101951.17647058 with a remaining 5.32e-07.
