We look at the division of 63424384 by 436 
The aim is to understand the frequency of 436 in 63424384.

Advancing to step 1:
The number 436 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 436

Advancing to step 2:
The number 436 fits into 63 0 times, leaving a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Append the next digit (4) from the dividend to 63 and continue with: 634 / 436

Advancing to step 3:
If we divide 634 by 436, we get 1 and a remainder of 198.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 436 away from 634, we end up with 198.
Fetch the next digit (2) from the dividend, attach it to 198 and continue: 1982 / 436

Let's proceed to step 4:
436 can be fit into 1982 4 times, resulting in a remainder of 238.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 1744 from 1982, we get 238.
Fetch the next digit (4) from the dividend, attach it to 238 and continue: 2384 / 436

Moving on to step 5:
When dividing 2384 by 436, we get 5 with a remainder of 204.
The next digit of our result is 5. 
Result so far: 145.0
Deduct 2180 from 2384 and we're left with 204.
Include the next digit (3) from the dividend after 204, then repeat: 2043 / 436

On to step 6:
If we divide 2043 by 436, we get 4 and a remainder of 299.
The number 4 becomes the next digit in our result. 
Result so far: 1454.0
The remainder is 299 after subtracting 1744 from 2043.
Append the next digit (8) from the dividend to 299 and continue with: 2998 / 436

Moving on to step 7:
The number 436 fits into 2998 6 times, leaving a remainder of 382.
Put 6 as the next digit of the answer. 
Result so far: 14546.0
Subtract 2616 from 2998 to get 382.
Fetch the next digit (4) from the dividend, attach it to 382 and continue: 3824 / 436

Going ahead to step 8:
3824 divided by 436 is 8 with a remainder of 336.
The number 8 becomes the next digit in our result. 
Result so far: 145468.0
Subtract 3488 from 3824 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 9:
436 can be fit into 3360 7 times, resulting in a remainder of 308.
Put 7 as the next digit of the answer. 
Result so far: 145468.7
Deduct 3052 from 3360 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 10:
436 goes into 3080 7 times with a remainder of 28.
The next digit of our result is 7. 
Result so far: 145468.77
Subtracting 3052 from 3080 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 145468.77, and the remainder is 0.028.
