We look at the division of 75181572 by 189 
The aim is to understand the frequency of 189 in 75181572.

Moving on to step 1:
189 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 189

Advancing to step 2:
189 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Take the next digit (1) from the dividend and append it to 75, then repeat: 751 / 189

Moving on to step 3:
If we divide 751 by 189, we get 3 and a remainder of 184.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 567 from 751, we get 184.
Include the next digit (8) from the dividend after 184, then repeat: 1848 / 189

Moving on to step 4:
The number 189 fits into 1848 9 times, leaving a remainder of 147.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 1701 from 1848, we get 147.
Append the next digit (1) from the dividend to 147 and continue with: 1471 / 189

Moving on to step 5:
189 can be fit into 1471 7 times, resulting in a remainder of 148.
Put 7 as the next digit of the answer. 
Result so far: 397.0
If we take 1323 away from 1471, we end up with 148.
Bring next digit (5) of the dividend behind the 148 and repeat the process: 1485 / 189

Let's proceed to step 6:
The number 189 fits into 1485 7 times, leaving a remainder of 162.
The number 7 becomes the next digit in our result. 
Result so far: 3977.0
If we take 1323 away from 1485, we end up with 162.
Include the next digit (7) from the dividend after 162, then repeat: 1627 / 189

Advancing to step 7:
If we divide 1627 by 189, we get 8 and a remainder of 115.
The next digit of our result is 8. 
Result so far: 39778.0
Deduct 1512 from 1627 and we're left with 115.
Fetch the next digit (2) from the dividend, attach it to 115 and continue: 1152 / 189

On to step 8:
189 can be fit into 1152 6 times, resulting in a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 397786.0
If we take 1134 away from 1152, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
189 can be fit into 180 0 times, resulting in a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 397786.0
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
When dividing 1800 by 189, we get 9 with a remainder of 99.
The next digit of our result is 9. 
Result so far: 397786.09
If we take 1701 away from 1800, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 11:
189 can be fit into 990 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 397786.095
If we take 945 away from 990, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 12:
The number 189 fits into 450 2 times, leaving a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 397786.0952
Subtract 378 from 450 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
720 divided by 189 is 3 with a remainder of 153.
Put 3 as the next digit of the answer. 
Result so far: 397786.09523
Subtracting 567 from 720 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 14:
The number 189 fits into 1530 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 397786.095238
The remainder is 18 after subtracting 1512 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 15:
If we divide 180 by 189, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 397786.095238
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 16:
189 goes into 1800 9 times with a remainder of 99.
Record the quotient 9 as the next digit in the result. 
Result so far: 397786.09523809
Subtract 1701 from 1800 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

The quotient of the division is 397786.09523809, and the remainder is 9.9e-08.
