We divide 68107127 by 646
The aim is to understand the frequency of 646 in 68107127.

On to step 1:
When dividing 6 by 646, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 646

Moving on to step 2:
646 goes into 68 0 times with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 646

Step 3:
The number 646 fits into 681 1 times, leaving a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 646 away from 681, we end up with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 646

Going ahead to step 4:
646 can be fit into 350 0 times, resulting in a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 350 leaves us with 350.
Grab the next digit (7) from the dividend, add it to 350, then carry on: 3507 / 646

Step 5:
646 can be fit into 3507 5 times, resulting in a remainder of 277.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
If we take 3230 away from 3507, we end up with 277.
Take the next digit (1) from the dividend and append it to 277, then repeat: 2771 / 646

Advancing to step 6:
646 can be fit into 2771 4 times, resulting in a remainder of 187.
The next digit of our result is 4. 
Result so far: 1054.0
Subtracting 2584 from 2771 leaves us with 187.
Include the next digit (2) from the dividend after 187, then repeat: 1872 / 646

Going ahead to step 7:
646 can be fit into 1872 2 times, resulting in a remainder of 580.
The number 2 becomes the next digit in our result. 
Result so far: 10542.0
Subtract 1292 from 1872 to get 580.
Take the next digit (7) from the dividend and append it to 580, then repeat: 5807 / 646

Going ahead to step 8:
If we divide 5807 by 646, we get 8 and a remainder of 639.
Use 8 as the next digit of our solution. 
Result so far: 105428.0
If we subtract 5168 from 5807, we get 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Going ahead to step 9:
The number 646 fits into 6390 9 times, leaving a remainder of 576.
Use 9 as the next digit of our solution. 
Result so far: 105428.9
If we subtract 5814 from 6390, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 10:
The number 646 fits into 5760 8 times, leaving a remainder of 592.
Put 8 as the next digit of the answer. 
Result so far: 105428.98
Subtracting 5168 from 5760 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 11:
The number 646 fits into 5920 9 times, leaving a remainder of 106.
Write down 9 as next digit of the result. 
Result so far: 105428.989
The remainder is 106 after subtracting 5814 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 12:
1060 divided by 646 is 1 with a remainder of 414.
Write down 1 as next digit of the result. 
Result so far: 105428.9891
Subtract 646 from 1060 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 13:
When dividing 4140 by 646, we get 6 with a remainder of 264.
Use 6 as the next digit of our solution. 
Result so far: 105428.98916
If we subtract 3876 from 4140, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 14:
When dividing 2640 by 646, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 105428.989164
If we subtract 2584 from 2640, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 15:
646 goes into 560 0 times with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 105428.989164
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 16:
5600 divided by 646 is 8 with a remainder of 432.
The number 8 becomes the next digit in our result. 
Result so far: 105428.98916408
The remainder is 432 after subtracting 5168 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

The final result is 105428.98916408 with a remainder of 4.32e-07.
