We're dividing 23571797 by 669 
The aim is to understand the frequency of 669 in 23571797.

Let's proceed to step 1:
The number 669 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 669

Moving on to step 2:
If we divide 23 by 669, we get 0 and a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 669

Moving on to step 3:
If we divide 235 by 669, we get 0 and a remainder of 235.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 235 leaves us with 235.
Append the next digit (7) from the dividend to 235 and continue with: 2357 / 669

Let's proceed to step 4:
669 goes into 2357 3 times with a remainder of 350.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2007 from 2357 to get 350.
Fetch the next digit (1) from the dividend, attach it to 350 and continue: 3501 / 669

Going ahead to step 5:
3501 divided by 669 is 5 with a remainder of 156.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we take 3345 away from 3501, we end up with 156.
Grab the next digit (7) from the dividend, add it to 156, then carry on: 1567 / 669

On to step 6:
The number 669 fits into 1567 2 times, leaving a remainder of 229.
Put 2 as the next digit of the answer. 
Result so far: 352.0
If we subtract 1338 from 1567, we get 229.
Include the next digit (9) from the dividend after 229, then repeat: 2299 / 669

Let's proceed to step 7:
669 goes into 2299 3 times with a remainder of 292.
Put 3 as the next digit of the answer. 
Result so far: 3523.0
Deduct 2007 from 2299 and we're left with 292.
Fetch the next digit (7) from the dividend, attach it to 292 and continue: 2927 / 669

Moving on to step 8:
If we divide 2927 by 669, we get 4 and a remainder of 251.
Write down 4 as next digit of the result. 
Result so far: 35234.0
The remainder is 251 after subtracting 2676 from 2927.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 9:
If we divide 2510 by 669, we get 3 and a remainder of 503.
Use 3 as the next digit of our solution. 
Result so far: 35234.3
Subtracting 2007 from 2510 leaves us with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

On to step 10:
669 goes into 5030 7 times with a remainder of 347.
Put 7 as the next digit of the answer. 
Result so far: 35234.37
The remainder is 347 after subtracting 4683 from 5030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Let's proceed to step 11:
669 goes into 3470 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 35234.375
Subtract 3345 from 3470 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 12:
1250 divided by 669 is 1 with a remainder of 581.
Write down 1 as next digit of the result. 
Result so far: 35234.3751
The remainder is 581 after subtracting 669 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

On to step 13:
669 can be fit into 5810 8 times, resulting in a remainder of 458.
Write down 8 as next digit of the result. 
Result so far: 35234.37518
Subtract 5352 from 5810 to get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 14:
If we divide 4580 by 669, we get 6 and a remainder of 566.
Write down 6 as next digit of the result. 
Result so far: 35234.375186
Subtracting 4014 from 4580 leaves us with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Going ahead to step 15:
The number 669 fits into 5660 8 times, leaving a remainder of 308.
Record the quotient 8 as the next digit in the result. 
Result so far: 35234.3751868
If we subtract 5352 from 5660, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 16:
669 can be fit into 3080 4 times, resulting in a remainder of 404.
Use 4 as the next digit of our solution. 
Result so far: 35234.37518684
Deduct 2676 from 3080 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

The quotient of the division is 35234.37518684, and the remainder is 4.04e-07.
