67979493 ÷ 109 
The aim is to understand the frequency of 109 in 67979493.

Moving on to step 1:
The number 109 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 109

Step 2:
If we divide 67 by 109, we get 0 and a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 109

Let's proceed to step 3:
679 divided by 109 is 6 with a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 654 from 679 leaves us with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 109

On to step 4:
The number 109 fits into 257 2 times, leaving a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Deduct 218 from 257 and we're left with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 109

Advancing to step 5:
The number 109 fits into 399 3 times, leaving a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 623.0
Subtract 327 from 399 to get 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 109

Step 6:
724 divided by 109 is 6 with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 6236.0
If we subtract 654 from 724, we get 70.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 109

Let's proceed to step 7:
If we divide 709 by 109, we get 6 and a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 62366.0
The remainder is 55 after subtracting 654 from 709.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 109

Going ahead to step 8:
If we divide 553 by 109, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 623665.0
If we subtract 545 from 553, 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.

On to step 9:
The number 109 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 623665.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
109 can be fit into 800 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 623665.07
Subtract 763 from 800 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
If we divide 370 by 109, we get 3 and a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 623665.073
If we subtract 327 from 370, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 12:
430 divided by 109 is 3 with a remainder of 103.
The number 3 becomes the next digit in our result. 
Result so far: 623665.0733
Deduct 327 from 430 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

After the division, we end up with 623665.0733 and a remainder of 0.00103.
