We look at the division of 67190251 by 105 
The aim is to understand the frequency of 105 in 67190251.

Going ahead to step 1:
105 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 105

Going ahead to step 2:
The number 105 fits into 67 0 times, leaving a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Include the next digit (1) from the dividend after 67, then repeat: 671 / 105

Going ahead to step 3:
When dividing 671 by 105, we get 6 with a remainder of 41.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 630 from 671 and we're left with 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 105

Moving on to step 4:
The number 105 fits into 419 3 times, leaving a remainder of 104.
Write down 3 as next digit of the result. 
Result so far: 63.0
If we subtract 315 from 419, we get 104.
Include the next digit (0) from the dividend after 104, then repeat: 1040 / 105

On to step 5:
If we divide 1040 by 105, we get 9 and a remainder of 95.
The next digit of our result is 9. 
Result so far: 639.0
Deduct 945 from 1040 and we're left with 95.
Append the next digit (2) from the dividend to 95 and continue with: 952 / 105

Advancing to step 6:
105 goes into 952 9 times with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 6399.0
If we subtract 945 from 952, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 105

On to step 7:
105 can be fit into 75 0 times, resulting in a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 63990.0
Subtract 0 from 75 to get 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 105

Going ahead to step 8:
When dividing 751 by 105, we get 7 with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 639907.0
If we take 735 away from 751, we end up 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.

On to step 9:
If we divide 160 by 105, we get 1 and a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 639907.1
If we take 105 away from 160, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
The number 105 fits into 550 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 639907.15
Subtracting 525 from 550 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
If we divide 250 by 105, we get 2 and a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 639907.152
Deduct 210 from 250 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
105 can be fit into 400 3 times, resulting in a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 639907.1523
If we subtract 315 from 400, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 13:
The number 105 fits into 850 8 times, leaving a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 639907.15238
If we take 840 away from 850, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
100 divided by 105 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 639907.15238
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 15:
When dividing 1000 by 105, we get 9 with a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 639907.1523809
Deduct 945 from 1000 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 16:
If we divide 550 by 105, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 639907.15238095
Deduct 525 from 550 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 639907.15238095 and a remainder of 2.5e-08.
