We look at the division of 77421007 by 195 
The aim is to understand the frequency of 195 in 77421007.

Going ahead to step 1:
7 divided by 195 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 195

Step 2:
195 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 195

On to step 3:
The number 195 fits into 774 3 times, leaving a remainder of 189.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 585 from 774 to get 189.
Bring next digit (2) of the dividend behind the 189 and repeat the process: 1892 / 195

Step 4:
195 goes into 1892 9 times with a remainder of 137.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 1755 away from 1892, we end up with 137.
Append the next digit (1) from the dividend to 137 and continue with: 1371 / 195

Let's proceed to step 5:
The number 195 fits into 1371 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 397.0
Subtracting 1365 from 1371 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 195

Moving on to step 6:
If we divide 60 by 195, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 3970.0
If we subtract 0 from 60, we get 60.
Append the next digit (0) from the dividend to 60 and continue with: 600 / 195

Step 7:
The number 195 fits into 600 3 times, leaving a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 39703.0
If we subtract 585 from 600, we get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 195

Let's proceed to step 8:
195 can be fit into 157 0 times, resulting in a remainder of 157.
The number 0 becomes the next digit in our result. 
Result so far: 397030.0
If we take 0 away from 157, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 9:
1570 divided by 195 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 397030.8
If we subtract 1560 from 1570, 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.

Let's proceed to step 10:
When dividing 100 by 195, we get 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 397030.8
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
195 can be fit into 1000 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 397030.805
The remainder is 25 after subtracting 975 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
When dividing 250 by 195, we get 1 with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 397030.8051
Subtract 195 from 250 to 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.

Moving on to step 13:
195 can be fit into 550 2 times, resulting in a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 397030.80512
Subtract 390 from 550 to 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.

Step 14:
195 goes into 1600 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 397030.805128
If we subtract 1560 from 1600, we 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 15:
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: 397030.8051282
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.

Advancing to step 16:
195 goes into 100 0 times with a remainder of 100.
The next digit of our result is 0. 
Result so far: 397030.8051282
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 397030.8051282, and the remainder is 1e-07.
