30619 ÷ 68 
The aim is to understand the frequency of 68 in 30619.

Let's proceed to step 1:
3 divided by 68 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 68

Advancing to step 2:
The number 68 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 68

On to step 3:
306 divided by 68 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 272 from 306 and we're left with 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 68

Moving on to step 4:
68 goes into 341 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Deduct 340 from 341 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 68

On to step 5:
68 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 450.0
The remainder is 19 after subtracting 0 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 6:
When dividing 190 by 68, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 450.2
Deduct 136 from 190 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
When dividing 540 by 68, we get 7 with a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 450.27
Deduct 476 from 540 and we're left 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.

Going ahead to step 8:
640 divided by 68 is 9 with a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 450.279
If we subtract 612 from 640, we 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.

On to step 9:
280 divided by 68 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 450.2794
If we take 272 away from 280, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 68 fits into 80 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 450.27941
Subtract 68 from 80 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
120 divided by 68 is 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 450.279411
Deduct 68 from 120 and we're left 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.

Our division results in 450.279411 with a remaining 5.2e-06.
