10933990 divided by 159 
The aim is to understand the frequency of 159 in 10933990.

Moving on to step 1:
159 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 159

On to step 2:
10 divided by 159 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 159

Let's proceed to step 3:
If we divide 109 by 159, we get 0 and a remainder of 109.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 109, we get 109.
Fetch the next digit (3) from the dividend, attach it to 109 and continue: 1093 / 159

Advancing to step 4:
159 goes into 1093 6 times with a remainder of 139.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 139 after subtracting 954 from 1093.
Bring next digit (3) of the dividend behind the 139 and repeat the process: 1393 / 159

Step 5:
1393 divided by 159 is 8 with a remainder of 121.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Deduct 1272 from 1393 and we're left with 121.
Grab the next digit (9) from the dividend, add it to 121, then carry on: 1219 / 159

Moving on to step 6:
When dividing 1219 by 159, we get 7 with a remainder of 106.
Record the quotient 7 as the next digit in the result. 
Result so far: 687.0
If we take 1113 away from 1219, we end up with 106.
Append the next digit (9) from the dividend to 106 and continue with: 1069 / 159

Step 7:
159 goes into 1069 6 times with a remainder of 115.
Use 6 as the next digit of our solution. 
Result so far: 6876.0
If we take 954 away from 1069, we end up with 115.
Include the next digit (0) from the dividend after 115, then repeat: 1150 / 159

Advancing to step 8:
159 can be fit into 1150 7 times, resulting in a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 68767.0
If we take 1113 away from 1150, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
159 goes into 370 2 times with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 68767.2
The remainder is 52 after subtracting 318 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
When dividing 520 by 159, we get 3 with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 68767.23
Deduct 477 from 520 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 11:
159 goes into 430 2 times with a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 68767.232
Subtract 318 from 430 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 12:
The number 159 fits into 1120 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 68767.2327
Subtract 1113 from 1120 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
If we divide 70 by 159, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 68767.2327
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
700 divided by 159 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 68767.232704
If we subtract 636 from 700, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 15:
When dividing 640 by 159, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 68767.2327044
The remainder is 4 after subtracting 636 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 68767.2327044, with a leftover of 4e-08.
