67993430 ÷ 159 
The aim is to understand the frequency of 159 in 67993430.

Let's proceed to step 1:
6 divided by 159 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 159

Moving on to step 2:
If we divide 67 by 159, we get 0 and a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 159

On to step 3:
159 goes into 679 4 times with a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 636 away from 679, we end up with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 159

Moving on to step 4:
159 goes into 439 2 times with a remainder of 121.
The next digit of our result is 2. 
Result so far: 42.0
Subtract 318 from 439 to get 121.
Append the next digit (3) from the dividend to 121 and continue with: 1213 / 159

On to step 5:
159 goes into 1213 7 times with a remainder of 100.
Write down 7 as next digit of the result. 
Result so far: 427.0
If we take 1113 away from 1213, we end up with 100.
Fetch the next digit (4) from the dividend, attach it to 100 and continue: 1004 / 159

On to step 6:
When dividing 1004 by 159, we get 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 4276.0
Deduct 954 from 1004 and we're left with 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 159

Going ahead to step 7:
When dividing 503 by 159, we get 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 42763.0
The remainder is 26 after subtracting 477 from 503.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 159

Let's proceed to step 8:
260 divided by 159 is 1 with a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 427631.0
If we take 159 away from 260, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 9:
When dividing 1010 by 159, we get 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 427631.6
The remainder is 56 after subtracting 954 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
The number 159 fits into 560 3 times, leaving a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 427631.63
The remainder is 83 after subtracting 477 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 11:
The number 159 fits into 830 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 427631.635
The remainder is 35 after subtracting 795 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
350 divided by 159 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 427631.6352
If we take 318 away from 350, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
The number 159 fits into 320 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 427631.63522
Subtract 318 from 320 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 427631.63522, and the remainder is 2e-06.
