Let's divide 7289721 by 189
The aim is to understand the frequency of 189 in 7289721.

Moving on to step 1:
If we divide 7 by 189, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 189

Moving on to step 2:
If we divide 72 by 189, we get 0 and a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 189

Step 3:
When dividing 728 by 189, we get 3 with a remainder of 161.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 567 from 728 to get 161.
Include the next digit (9) from the dividend after 161, then repeat: 1619 / 189

Advancing to step 4:
If we divide 1619 by 189, we get 8 and a remainder of 107.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 1512 from 1619 to get 107.
Fetch the next digit (7) from the dividend, attach it to 107 and continue: 1077 / 189

Advancing to step 5:
The number 189 fits into 1077 5 times, leaving a remainder of 132.
The number 5 becomes the next digit in our result. 
Result so far: 385.0
Subtracting 945 from 1077 leaves us with 132.
Fetch the next digit (2) from the dividend, attach it to 132 and continue: 1322 / 189

Going ahead to step 6:
When dividing 1322 by 189, we get 6 with a remainder of 188.
Write down 6 as next digit of the result. 
Result so far: 3856.0
The remainder is 188 after subtracting 1134 from 1322.
Append the next digit (1) from the dividend to 188 and continue with: 1881 / 189

On to step 7:
If we divide 1881 by 189, we get 9 and a remainder of 180.
Use 9 as the next digit of our solution. 
Result so far: 38569.0
Deduct 1701 from 1881 and we're left with 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 8:
The number 189 fits into 1800 9 times, leaving a remainder of 99.
Use 9 as the next digit of our solution. 
Result so far: 38569.9
Subtracting 1701 from 1800 leaves us 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 9:
990 divided by 189 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 38569.95
If we subtract 945 from 990, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
189 goes into 450 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 38569.952
Deduct 378 from 450 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
The number 189 fits into 720 3 times, leaving a remainder of 153.
Use 3 as the next digit of our solution. 
Result so far: 38569.9523
The remainder is 153 after subtracting 567 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 12:
When dividing 1530 by 189, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 38569.95238
If we subtract 1512 from 1530, we get 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 13:
When dividing 180 by 189, we get 0 with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 38569.95238
Subtracting 0 from 180 leaves us with 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 14:
1800 divided by 189 is 9 with a remainder of 99.
Write down 9 as next digit of the result. 
Result so far: 38569.9523809
The remainder is 99 after subtracting 1701 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 15:
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: 38569.95238095
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.

In conclusion, the division gives 38569.95238095 with a balance of 4.5e-08.
