Let's divide 56291133 by 428
The aim is to understand the frequency of 428 in 56291133.

Going ahead to step 1:
5 divided by 428 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 428

Advancing to step 2:
The number 428 fits into 56 0 times, leaving a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Grab the next digit (2) from the dividend, add it to 56, then carry on: 562 / 428

On to step 3:
428 goes into 562 1 times with a remainder of 134.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 428 from 562 to get 134.
Grab the next digit (9) from the dividend, add it to 134, then carry on: 1349 / 428

Let's proceed to step 4:
428 goes into 1349 3 times with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1284 from 1349 to get 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 428

Step 5:
When dividing 651 by 428, we get 1 with a remainder of 223.
The next digit of our result is 1. 
Result so far: 131.0
The remainder is 223 after subtracting 428 from 651.
Take the next digit (1) from the dividend and append it to 223, then repeat: 2231 / 428

Going ahead to step 6:
2231 divided by 428 is 5 with a remainder of 91.
Record the quotient 5 as the next digit in the result. 
Result so far: 1315.0
If we subtract 2140 from 2231, we get 91.
Bring next digit (3) of the dividend behind the 91 and repeat the process: 913 / 428

Step 7:
If we divide 913 by 428, we get 2 and a remainder of 57.
Write down 2 as next digit of the result. 
Result so far: 13152.0
Subtracting 856 from 913 leaves us with 57.
Bring next digit (3) of the dividend behind the 57 and repeat the process: 573 / 428

Step 8:
428 can be fit into 573 1 times, resulting in a remainder of 145.
The next digit of our result is 1. 
Result so far: 131521.0
If we subtract 428 from 573, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 9:
The number 428 fits into 1450 3 times, leaving a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 131521.3
Deduct 1284 from 1450 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 10:
428 goes into 1660 3 times with a remainder of 376.
The number 3 becomes the next digit in our result. 
Result so far: 131521.33
Subtract 1284 from 1660 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final outcome is 131521.33, with a leftover of 0.376.
