7533091 ÷ 159 
The aim is to understand the frequency of 159 in 7533091.

Moving on to step 1:
If we divide 7 by 159, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 159

Let's proceed to step 2:
If we divide 75 by 159, we get 0 and a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 159

Let's proceed to step 3:
159 can be fit into 753 4 times, resulting in a remainder of 117.
The next digit of our result is 4. 
Result so far: 4.0
If we take 636 away from 753, we end up with 117.
Include the next digit (3) from the dividend after 117, then repeat: 1173 / 159

Going ahead to step 4:
1173 divided by 159 is 7 with a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtracting 1113 from 1173 leaves us with 60.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 159

Moving on to step 5:
When dividing 600 by 159, we get 3 with a remainder of 123.
Write down 3 as next digit of the result. 
Result so far: 473.0
The remainder is 123 after subtracting 477 from 600.
Fetch the next digit (9) from the dividend, attach it to 123 and continue: 1239 / 159

Let's proceed to step 6:
The number 159 fits into 1239 7 times, leaving a remainder of 126.
Put 7 as the next digit of the answer. 
Result so far: 4737.0
Deduct 1113 from 1239 and we're left with 126.
Grab the next digit (1) from the dividend, add it to 126, then carry on: 1261 / 159

Step 7:
159 goes into 1261 7 times with a remainder of 148.
Put 7 as the next digit of the answer. 
Result so far: 47377.0
The remainder is 148 after subtracting 1113 from 1261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 8:
If we divide 1480 by 159, we get 9 and a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 47377.9
Subtract 1431 from 1480 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
490 divided by 159 is 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 47377.93
Deduct 477 from 490 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
159 can be fit into 130 0 times, resulting in a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 47377.93
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 11:
1300 divided by 159 is 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 47377.9308
Subtract 1272 from 1300 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
The number 159 fits into 280 1 times, leaving a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 47377.93081
Subtract 159 from 280 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 13:
1210 divided by 159 is 7 with a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 47377.930817
Deduct 1113 from 1210 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 14:
If we divide 970 by 159, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 47377.9308176
Subtract 954 from 970 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 15:
159 can be fit into 160 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 47377.93081761
If we subtract 159 from 160, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 47377.93081761 with a remaining 1e-09.
