We look at the division of 76124921 by 195 
The aim is to understand the frequency of 195 in 76124921.

Step 1:
195 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 195

On to step 2:
The number 195 fits into 76 0 times, leaving a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 195

Advancing to step 3:
When dividing 761 by 195, we get 3 with a remainder of 176.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 585 from 761 and we're left with 176.
Take the next digit (2) from the dividend and append it to 176, then repeat: 1762 / 195

Let's proceed to step 4:
195 can be fit into 1762 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 1755 from 1762 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 195

Let's proceed to step 5:
If we divide 74 by 195, we get 0 and a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 390.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (9) of the dividend behind the 74 and repeat the process: 749 / 195

Moving on to step 6:
749 divided by 195 is 3 with a remainder of 164.
Write down 3 as next digit of the result. 
Result so far: 3903.0
If we subtract 585 from 749, we get 164.
Fetch the next digit (2) from the dividend, attach it to 164 and continue: 1642 / 195

Going ahead to step 7:
195 can be fit into 1642 8 times, resulting in a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 39038.0
Subtract 1560 from 1642 to get 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 195

Step 8:
195 goes into 821 4 times with a remainder of 41.
Use 4 as the next digit of our solution. 
Result so far: 390384.0
Deduct 780 from 821 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
If we divide 410 by 195, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 390384.2
Deduct 390 from 410 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
When dividing 200 by 195, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 390384.21
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
195 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 390384.21
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
If we divide 500 by 195, we get 2 and a remainder of 110.
Write down 2 as next digit of the result. 
Result so far: 390384.2102
If we subtract 390 from 500, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 13:
195 can be fit into 1100 5 times, resulting in a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 390384.21025
Subtracting 975 from 1100 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 14:
If we divide 1250 by 195, we get 6 and a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 390384.210256
Subtracting 1170 from 1250 leaves us 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.

Step 15:
195 goes into 800 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 390384.2102564
Deduct 780 from 800 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 16:
When dividing 200 by 195, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 390384.21025641
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 390384.21025641, and the remainder is 5e-09.
