Let's divide 50123543 by 436
The aim is to understand the frequency of 436 in 50123543.

Advancing to step 1:
If we divide 5 by 436, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 436

Going ahead to step 2:
If we divide 50 by 436, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 436

Let's proceed to step 3:
436 can be fit into 501 1 times, resulting in a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 436 from 501 to get 65.
Take the next digit (2) from the dividend and append it to 65, then repeat: 652 / 436

Advancing to step 4:
436 can be fit into 652 1 times, resulting in a remainder of 216.
The next digit of our result is 1. 
Result so far: 11.0
If we take 436 away from 652, we end up with 216.
Take the next digit (3) from the dividend and append it to 216, then repeat: 2163 / 436

Let's proceed to step 5:
436 can be fit into 2163 4 times, resulting in a remainder of 419.
Use 4 as the next digit of our solution. 
Result so far: 114.0
If we take 1744 away from 2163, we end up with 419.
Include the next digit (5) from the dividend after 419, then repeat: 4195 / 436

Moving on to step 6:
When dividing 4195 by 436, we get 9 with a remainder of 271.
Use 9 as the next digit of our solution. 
Result so far: 1149.0
The remainder is 271 after subtracting 3924 from 4195.
Grab the next digit (4) from the dividend, add it to 271, then carry on: 2714 / 436

Step 7:
2714 divided by 436 is 6 with a remainder of 98.
The number 6 becomes the next digit in our result. 
Result so far: 11496.0
Subtract 2616 from 2714 to get 98.
Bring next digit (3) of the dividend behind the 98 and repeat the process: 983 / 436

Going ahead to step 8:
436 goes into 983 2 times with a remainder of 111.
Put 2 as the next digit of the answer. 
Result so far: 114962.0
Subtracting 872 from 983 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 9:
If we divide 1110 by 436, we get 2 and a remainder of 238.
Put 2 as the next digit of the answer. 
Result so far: 114962.2
The remainder is 238 after subtracting 872 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 10:
When dividing 2380 by 436, we get 5 with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 114962.25
Subtract 2180 from 2380 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
When dividing 2000 by 436, we get 4 with a remainder of 256.
The next digit of our result is 4. 
Result so far: 114962.254
If we subtract 1744 from 2000, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 12:
2560 divided by 436 is 5 with a remainder of 380.
The next digit of our result is 5. 
Result so far: 114962.2545
If we subtract 2180 from 2560, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 13:
436 goes into 3800 8 times with a remainder of 312.
Write down 8 as next digit of the result. 
Result so far: 114962.25458
Subtract 3488 from 3800 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 14:
When dividing 3120 by 436, we get 7 with a remainder of 68.
Use 7 as the next digit of our solution. 
Result so far: 114962.254587
Subtract 3052 from 3120 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 15:
If we divide 680 by 436, we get 1 and a remainder of 244.
The number 1 becomes the next digit in our result. 
Result so far: 114962.2545871
Subtracting 436 from 680 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 16:
The number 436 fits into 2440 5 times, leaving a remainder of 260.
Put 5 as the next digit of the answer. 
Result so far: 114962.25458715
The remainder is 260 after subtracting 2180 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Our division results in 114962.25458715 with a remaining 2.6e-07.
