195151 divided by 42 
The aim is to understand the frequency of 42 in 195151.

Advancing to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 42

On to step 2:
When dividing 19 by 42, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 42

Let's proceed to step 3:
42 can be fit into 195 4 times, resulting in a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 168 from 195 leaves us with 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 42

Going ahead to step 4:
42 goes into 271 6 times with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Subtracting 252 from 271 leaves us with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 42

Going ahead to step 5:
The number 42 fits into 195 4 times, leaving a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 464.0
Subtract 168 from 195 to get 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 42

Going ahead to step 6:
If we divide 271 by 42, we get 6 and a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 4646.0
If we take 252 away from 271, we end up with 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 7:
When dividing 190 by 42, we get 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 4646.4
If we subtract 168 from 190, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
When dividing 220 by 42, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 4646.45
If we take 210 away from 220, 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.

Moving on to step 9:
100 divided by 42 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 4646.452
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
160 divided by 42 is 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 4646.4523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
When dividing 340 by 42, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 4646.45238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
When dividing 40 by 42, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4646.45238
Deduct 0 from 40 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.

Going ahead to step 13:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 4646.4523809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
When dividing 220 by 42, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 4646.45238095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 4646.45238095, with a leftover of 1e-08.
