We look at the division of 223361 by 68 
The aim is to understand the frequency of 68 in 223361.

Let's proceed to step 1:
If we divide 2 by 68, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 68

Advancing to step 2:
68 can be fit into 22 0 times, resulting in a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 68

Advancing to step 3:
When dividing 223 by 68, we get 3 with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 204 from 223 to get 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 68

On to step 4:
68 can be fit into 193 2 times, resulting in a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 136 from 193, we get 57.
Take the next digit (6) from the dividend and append it to 57, then repeat: 576 / 68

Advancing to step 5:
The number 68 fits into 576 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 328.0
Subtract 544 from 576 to get 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 68

Advancing to step 6:
The number 68 fits into 321 4 times, leaving a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 3284.0
The remainder is 49 after subtracting 272 from 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
68 goes into 490 7 times with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 3284.7
Subtract 476 from 490 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
The number 68 fits into 140 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 3284.72
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
If we divide 40 by 68, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3284.72
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
68 can be fit into 400 5 times, resulting in a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 3284.7205
Subtracting 340 from 400 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.

Moving on to step 11:
When dividing 600 by 68, we get 8 with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 3284.72058
The remainder is 56 after subtracting 544 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
If we divide 560 by 68, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3284.720588
Deduct 544 from 560 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 3284.720588, and the remainder is 1.6e-06.
