We look at the division of 78937915 by 195 
The aim is to understand the frequency of 195 in 78937915.

On to step 1:
If we divide 7 by 195, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 195

Let's proceed to step 2:
If we divide 78 by 195, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 195

Let's proceed to step 3:
The number 195 fits into 789 4 times, leaving a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 780 from 789 to get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 195

On to step 4:
195 goes into 93 0 times with a remainder of 93.
The next digit of our result is 0. 
Result so far: 40.0
The remainder is 93 after subtracting 0 from 93.
Fetch the next digit (7) from the dividend, attach it to 93 and continue: 937 / 195

Going ahead to step 5:
195 can be fit into 937 4 times, resulting in a remainder of 157.
Put 4 as the next digit of the answer. 
Result so far: 404.0
If we take 780 away from 937, we end up with 157.
Take the next digit (9) from the dividend and append it to 157, then repeat: 1579 / 195

Going ahead to step 6:
If we divide 1579 by 195, we get 8 and a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 4048.0
Subtract 1560 from 1579 to get 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 195

Advancing to step 7:
When dividing 191 by 195, we get 0 with a remainder of 191.
The next digit of our result is 0. 
Result so far: 40480.0
Deduct 0 from 191 and we're left with 191.
Bring next digit (5) of the dividend behind the 191 and repeat the process: 1915 / 195

Moving on to step 8:
1915 divided by 195 is 9 with a remainder of 160.
Use 9 as the next digit of our solution. 
Result so far: 404809.0
If we subtract 1755 from 1915, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 9:
195 can be fit into 1600 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 404809.8
If we take 1560 away from 1600, we end up 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.

Advancing to step 10:
If we divide 400 by 195, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 404809.82
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
100 divided by 195 is 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 404809.82
If we subtract 0 from 100, we 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.

Advancing to step 12:
195 can be fit into 1000 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 404809.8205
If we subtract 975 from 1000, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
The number 195 fits into 250 1 times, leaving a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 404809.82051
If we subtract 195 from 250, we get 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 14:
If we divide 550 by 195, we get 2 and a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 404809.820512
Deduct 390 from 550 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
When dividing 1600 by 195, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 404809.8205128
Subtract 1560 from 1600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 16:
195 goes into 400 2 times with a remainder of 10.
The next digit of our result is 2. 
Result so far: 404809.82051282
Deduct 390 from 400 and we're left 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.

Our division results in 404809.82051282 with a remaining 1e-08.
