We're dividing 71638343 by 436 
The aim is to understand the frequency of 436 in 71638343.

Let's proceed to step 1:
436 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 436

Advancing to step 2:
436 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 436

Step 3:
The number 436 fits into 716 1 times, leaving a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 436 from 716 and we're left with 280.
Include the next digit (3) from the dividend after 280, then repeat: 2803 / 436

Step 4:
The number 436 fits into 2803 6 times, leaving a remainder of 187.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 2616 away from 2803, we end up with 187.
Take the next digit (8) from the dividend and append it to 187, then repeat: 1878 / 436

On to step 5:
The number 436 fits into 1878 4 times, leaving a remainder of 134.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
Subtracting 1744 from 1878 leaves us with 134.
Append the next digit (3) from the dividend to 134 and continue with: 1343 / 436

Step 6:
436 can be fit into 1343 3 times, resulting in a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 1643.0
The remainder is 35 after subtracting 1308 from 1343.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 436

Let's proceed to step 7:
The number 436 fits into 354 0 times, leaving a remainder of 354.
Put 0 as the next digit of the answer. 
Result so far: 16430.0
Subtracting 0 from 354 leaves us with 354.
Append the next digit (3) from the dividend to 354 and continue with: 3543 / 436

Advancing to step 8:
The number 436 fits into 3543 8 times, leaving a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 164308.0
Subtracting 3488 from 3543 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 9:
The number 436 fits into 550 1 times, leaving a remainder of 114.
The number 1 becomes the next digit in our result. 
Result so far: 164308.1
Subtracting 436 from 550 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 10:
1140 divided by 436 is 2 with a remainder of 268.
Write down 2 as next digit of the result. 
Result so far: 164308.12
If we subtract 872 from 1140, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 11:
436 goes into 2680 6 times with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 164308.126
Subtracting 2616 from 2680 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
If we divide 640 by 436, we get 1 and a remainder of 204.
Record the quotient 1 as the next digit in the result. 
Result so far: 164308.1261
If we take 436 away from 640, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 13:
The number 436 fits into 2040 4 times, leaving a remainder of 296.
The next digit of our result is 4. 
Result so far: 164308.12614
Subtracting 1744 from 2040 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 14:
If we divide 2960 by 436, we get 6 and a remainder of 344.
Use 6 as the next digit of our solution. 
Result so far: 164308.126146
The remainder is 344 after subtracting 2616 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 15:
The number 436 fits into 3440 7 times, leaving a remainder of 388.
The next digit of our result is 7. 
Result so far: 164308.1261467
The remainder is 388 after subtracting 3052 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 16:
436 can be fit into 3880 8 times, resulting in a remainder of 392.
Write down 8 as next digit of the result. 
Result so far: 164308.12614678
If we subtract 3488 from 3880, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

In conclusion, the division gives 164308.12614678 with a balance of 3.92e-07.
