We look at the division of 89972689 by 436 
The aim is to understand the frequency of 436 in 89972689.

On to step 1:
The number 436 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 436

Let's proceed to step 2:
436 goes into 89 0 times with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Fetch the next digit (9) from the dividend, attach it to 89 and continue: 899 / 436

Moving on to step 3:
436 goes into 899 2 times with a remainder of 27.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 872 from 899 and we're left with 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 436

On to step 4:
The number 436 fits into 277 0 times, leaving a remainder of 277.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 277 to get 277.
Append the next digit (2) from the dividend to 277 and continue with: 2772 / 436

Moving on to step 5:
2772 divided by 436 is 6 with a remainder of 156.
The next digit of our result is 6. 
Result so far: 206.0
If we take 2616 away from 2772, we end up with 156.
Bring next digit (6) of the dividend behind the 156 and repeat the process: 1566 / 436

Step 6:
The number 436 fits into 1566 3 times, leaving a remainder of 258.
Write down 3 as next digit of the result. 
Result so far: 2063.0
Subtract 1308 from 1566 to get 258.
Take the next digit (8) from the dividend and append it to 258, then repeat: 2588 / 436

Moving on to step 7:
When dividing 2588 by 436, we get 5 with a remainder of 408.
Write down 5 as next digit of the result. 
Result so far: 20635.0
Subtract 2180 from 2588 to get 408.
Grab the next digit (9) from the dividend, add it to 408, then carry on: 4089 / 436

Going ahead to step 8:
The number 436 fits into 4089 9 times, leaving a remainder of 165.
Write down 9 as next digit of the result. 
Result so far: 206359.0
If we subtract 3924 from 4089, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 9:
The number 436 fits into 1650 3 times, leaving a remainder of 342.
Put 3 as the next digit of the answer. 
Result so far: 206359.3
If we subtract 1308 from 1650, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 10:
The number 436 fits into 3420 7 times, leaving a remainder of 368.
Record the quotient 7 as the next digit in the result. 
Result so far: 206359.37
Deduct 3052 from 3420 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 11:
When dividing 3680 by 436, we get 8 with a remainder of 192.
Use 8 as the next digit of our solution. 
Result so far: 206359.378
Deduct 3488 from 3680 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 12:
The number 436 fits into 1920 4 times, leaving a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 206359.3784
If we subtract 1744 from 1920, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 13:
If we divide 1760 by 436, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 206359.37844
If we subtract 1744 from 1760, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 206359.37844 with a remaining 1.6e-05.
