451397 divided by 68 
The aim is to understand the frequency of 68 in 451397.

Going ahead to step 1:
68 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 68

Moving on to step 2:
The number 68 fits into 45 0 times, leaving a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 68

Advancing to step 3:
68 goes into 451 6 times with a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 408 from 451, we get 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 68

On to step 4:
When dividing 433 by 68, we get 6 with a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 66.0
If we take 408 away from 433, we end up with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 68

Step 5:
68 goes into 259 3 times with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 663.0
Subtract 204 from 259 to get 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 68

Let's proceed to step 6:
557 divided by 68 is 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 6638.0
Subtracting 544 from 557 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
68 goes into 130 1 times with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 6638.1
Subtract 68 from 130 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
620 divided by 68 is 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 6638.19
If we subtract 612 from 620, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
If we divide 80 by 68, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 6638.191
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
68 goes into 120 1 times with a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 6638.1911
If we take 68 away from 120, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 6638.1911, with a leftover of 0.00052.
