Let's divide 52390486 by 133
The aim is to understand the frequency of 133 in 52390486.

Step 1:
If we divide 5 by 133, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 133

Let's proceed to step 2:
When dividing 52 by 133, we get 0 with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 133

Step 3:
The number 133 fits into 523 3 times, leaving a remainder of 124.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 399 away from 523, we end up with 124.
Take the next digit (9) from the dividend and append it to 124, then repeat: 1249 / 133

On to step 4:
When dividing 1249 by 133, we get 9 with a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 1197 from 1249 to get 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 133

Step 5:
When dividing 520 by 133, we get 3 with a remainder of 121.
Put 3 as the next digit of the answer. 
Result so far: 393.0
If we take 399 away from 520, we end up with 121.
Take the next digit (4) from the dividend and append it to 121, then repeat: 1214 / 133

Going ahead to step 6:
When dividing 1214 by 133, we get 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 3939.0
If we subtract 1197 from 1214, we get 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 133

Going ahead to step 7:
If we divide 178 by 133, we get 1 and a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 39391.0
Deduct 133 from 178 and we're left with 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 133

On to step 8:
The number 133 fits into 456 3 times, leaving a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 393913.0
The remainder is 57 after subtracting 399 from 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
570 divided by 133 is 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 393913.4
Deduct 532 from 570 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
When dividing 380 by 133, we get 2 with a remainder of 114.
The number 2 becomes the next digit in our result. 
Result so far: 393913.42
Subtracting 266 from 380 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 11:
The number 133 fits into 1140 8 times, leaving a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 393913.428
Subtract 1064 from 1140 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
760 divided by 133 is 5 with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 393913.4285
Deduct 665 from 760 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 13:
When dividing 950 by 133, we get 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 393913.42857
If we subtract 931 from 950, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 14:
If we divide 190 by 133, we get 1 and a remainder of 57.
The next digit of our result is 1. 
Result so far: 393913.428571
The remainder is 57 after subtracting 133 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 15:
When dividing 570 by 133, we get 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 393913.4285714
Deduct 532 from 570 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 16:
133 goes into 380 2 times with a remainder of 114.
Write down 2 as next digit of the result. 
Result so far: 393913.42857142
Subtract 266 from 380 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

In conclusion, the division gives 393913.42857142 with a balance of 1.14e-07.
