We look at the division of 43630263 by 569 
The aim is to understand the frequency of 569 in 43630263.

Step 1:
The number 569 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 569

On to step 2:
The number 569 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 569

Moving on to step 3:
569 goes into 436 0 times with a remainder of 436.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 436, we end up with 436.
Include the next digit (3) from the dividend after 436, then repeat: 4363 / 569

Moving on to step 4:
569 can be fit into 4363 7 times, resulting in a remainder of 380.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 3983 from 4363, we get 380.
Bring next digit (0) of the dividend behind the 380 and repeat the process: 3800 / 569

Going ahead to step 5:
If we divide 3800 by 569, we get 6 and a remainder of 386.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we subtract 3414 from 3800, we get 386.
Grab the next digit (2) from the dividend, add it to 386, then carry on: 3862 / 569

Step 6:
When dividing 3862 by 569, we get 6 with a remainder of 448.
The number 6 becomes the next digit in our result. 
Result so far: 766.0
If we subtract 3414 from 3862, we get 448.
Include the next digit (6) from the dividend after 448, then repeat: 4486 / 569

Moving on to step 7:
If we divide 4486 by 569, we get 7 and a remainder of 503.
Write down 7 as next digit of the result. 
Result so far: 7667.0
Deduct 3983 from 4486 and we're left with 503.
Bring next digit (3) of the dividend behind the 503 and repeat the process: 5033 / 569

Let's proceed to step 8:
If we divide 5033 by 569, we get 8 and a remainder of 481.
The next digit of our result is 8. 
Result so far: 76678.0
Subtract 4552 from 5033 to get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Moving on to step 9:
569 goes into 4810 8 times with a remainder of 258.
Write down 8 as next digit of the result. 
Result so far: 76678.8
If we take 4552 away from 4810, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 10:
When dividing 2580 by 569, we get 4 with a remainder of 304.
Write down 4 as next digit of the result. 
Result so far: 76678.84
If we subtract 2276 from 2580, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 11:
569 goes into 3040 5 times with a remainder of 195.
The next digit of our result is 5. 
Result so far: 76678.845
Subtracting 2845 from 3040 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 12:
The number 569 fits into 1950 3 times, leaving a remainder of 243.
Put 3 as the next digit of the answer. 
Result so far: 76678.8453
Subtract 1707 from 1950 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 13:
569 goes into 2430 4 times with a remainder of 154.
The number 4 becomes the next digit in our result. 
Result so far: 76678.84534
Subtract 2276 from 2430 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 14:
569 can be fit into 1540 2 times, resulting in a remainder of 402.
The number 2 becomes the next digit in our result. 
Result so far: 76678.845342
If we subtract 1138 from 1540, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 15:
When dividing 4020 by 569, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 76678.8453427
If we take 3983 away from 4020, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 16:
370 divided by 569 is 0 with a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 76678.8453427
The remainder is 370 after subtracting 0 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

After the division, we end up with 76678.8453427 and a remainder of 3.7e-07.
