We divide 40269825 by 609
The aim is to understand the frequency of 609 in 40269825.

Step 1:
When dividing 4 by 609, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 609

Going ahead to step 2:
The number 609 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 609

Step 3:
402 divided by 609 is 0 with a remainder of 402.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 402, we end up with 402.
Take the next digit (6) from the dividend and append it to 402, then repeat: 4026 / 609

Moving on to step 4:
609 goes into 4026 6 times with a remainder of 372.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 3654 away from 4026, we end up with 372.
Bring next digit (9) of the dividend behind the 372 and repeat the process: 3729 / 609

Moving on to step 5:
3729 divided by 609 is 6 with a remainder of 75.
Use 6 as the next digit of our solution. 
Result so far: 66.0
The remainder is 75 after subtracting 3654 from 3729.
Append the next digit (8) from the dividend to 75 and continue with: 758 / 609

Going ahead to step 6:
609 goes into 758 1 times with a remainder of 149.
Write down 1 as next digit of the result. 
Result so far: 661.0
Deduct 609 from 758 and we're left with 149.
Append the next digit (2) from the dividend to 149 and continue with: 1492 / 609

Step 7:
609 goes into 1492 2 times with a remainder of 274.
Record the quotient 2 as the next digit in the result. 
Result so far: 6612.0
If we take 1218 away from 1492, we end up with 274.
Bring next digit (5) of the dividend behind the 274 and repeat the process: 2745 / 609

Advancing to step 8:
609 can be fit into 2745 4 times, resulting in a remainder of 309.
The number 4 becomes the next digit in our result. 
Result so far: 66124.0
Deduct 2436 from 2745 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Advancing to step 9:
When dividing 3090 by 609, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 66124.5
If we take 3045 away from 3090, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
If we divide 450 by 609, we get 0 and a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 66124.5
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 11:
609 goes into 4500 7 times with a remainder of 237.
Record the quotient 7 as the next digit in the result. 
Result so far: 66124.507
If we take 4263 away from 4500, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 12:
If we divide 2370 by 609, we get 3 and a remainder of 543.
Put 3 as the next digit of the answer. 
Result so far: 66124.5073
If we take 1827 away from 2370, we end up with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Moving on to step 13:
The number 609 fits into 5430 8 times, leaving a remainder of 558.
The next digit of our result is 8. 
Result so far: 66124.50738
If we take 4872 away from 5430, we end up with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Going ahead to step 14:
The number 609 fits into 5580 9 times, leaving a remainder of 99.
Use 9 as the next digit of our solution. 
Result so far: 66124.507389
The remainder is 99 after subtracting 5481 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 15:
The number 609 fits into 990 1 times, leaving a remainder of 381.
Use 1 as the next digit of our solution. 
Result so far: 66124.5073891
If we subtract 609 from 990, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Moving on to step 16:
3810 divided by 609 is 6 with a remainder of 156.
The number 6 becomes the next digit in our result. 
Result so far: 66124.50738916
Subtract 3654 from 3810 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

After the division, we end up with 66124.50738916 and a remainder of 1.56e-07.
