646260 ÷ 68 
The aim is to understand the frequency of 68 in 646260.

On to step 1:
68 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 68

Moving on to step 2:
64 divided by 68 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 68

Going ahead to step 3:
The number 68 fits into 646 9 times, leaving a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 612 away from 646, we end up with 34.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 68

On to step 4:
68 goes into 342 5 times with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtracting 340 from 342 leaves us with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 68

Moving on to step 5:
26 divided by 68 is 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 950.0
If we subtract 0 from 26, we get 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 68

Step 6:
68 can be fit into 260 3 times, resulting in a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 9503.0
Subtract 204 from 260 to 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.

Let's proceed to step 7:
68 can be fit into 560 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 9503.8
If we subtract 544 from 560, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
160 divided by 68 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 9503.82
Subtract 136 from 160 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
240 divided by 68 is 3 with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 9503.823
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
If we divide 360 by 68, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 9503.8235
Subtracting 340 from 360 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
68 goes into 200 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 9503.82352
Subtracting 136 from 200 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
When dividing 640 by 68, we get 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 9503.823529
Subtract 612 from 640 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
68 can be fit into 280 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 9503.8235294
The remainder is 8 after subtracting 272 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
80 divided by 68 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 9503.82352941
Deduct 68 from 80 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 9503.82352941, and the remainder is 1.2e-08.
