53450299 ÷ 159 
The aim is to understand the frequency of 159 in 53450299.

Going ahead to step 1:
159 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 159

Moving on to step 2:
The number 159 fits into 53 0 times, leaving a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 159

Advancing to step 3:
534 divided by 159 is 3 with a remainder of 57.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 477 from 534, we get 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 159

Step 4:
If we divide 575 by 159, we get 3 and a remainder of 98.
Put 3 as the next digit of the answer. 
Result so far: 33.0
The remainder is 98 after subtracting 477 from 575.
Append the next digit (0) from the dividend to 98 and continue with: 980 / 159

Step 5:
If we divide 980 by 159, we get 6 and a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 336.0
If we take 954 away from 980, we end up with 26.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 159

Going ahead to step 6:
If we divide 262 by 159, we get 1 and a remainder of 103.
Record the quotient 1 as the next digit in the result. 
Result so far: 3361.0
The remainder is 103 after subtracting 159 from 262.
Take the next digit (9) from the dividend and append it to 103, then repeat: 1039 / 159

Step 7:
The number 159 fits into 1039 6 times, leaving a remainder of 85.
Record the quotient 6 as the next digit in the result. 
Result so far: 33616.0
The remainder is 85 after subtracting 954 from 1039.
Append the next digit (9) from the dividend to 85 and continue with: 859 / 159

Moving on to step 8:
If we divide 859 by 159, we get 5 and a remainder of 64.
The number 5 becomes the next digit in our result. 
Result so far: 336165.0
If we subtract 795 from 859, 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.

Step 9:
When dividing 640 by 159, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 336165.4
Subtract 636 from 640 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 159, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 336165.4
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 159 fits into 400 2 times, leaving a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 336165.402
Deduct 318 from 400 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 12:
820 divided by 159 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 336165.4025
The remainder is 25 after subtracting 795 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
250 divided by 159 is 1 with a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 336165.40251
If we take 159 away from 250, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 14:
If we divide 910 by 159, we get 5 and a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 336165.402515
If we take 795 away from 910, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 15:
159 goes into 1150 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 336165.4025157
Subtract 1113 from 1150 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 16:
370 divided by 159 is 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 336165.40251572
Subtract 318 from 370 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 336165.40251572 and a remainder of 5.2e-08.
