We're dividing 38030843 by 669 
The aim is to understand the frequency of 669 in 38030843.

Step 1:
The number 669 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 669

Going ahead to step 2:
669 goes into 38 0 times with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 669

Advancing to step 3:
The number 669 fits into 380 0 times, leaving a remainder of 380.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 380 after subtracting 0 from 380.
Take the next digit (3) from the dividend and append it to 380, then repeat: 3803 / 669

Moving on to step 4:
If we divide 3803 by 669, we get 5 and a remainder of 458.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 3345 from 3803 leaves us with 458.
Take the next digit (0) from the dividend and append it to 458, then repeat: 4580 / 669

Going ahead to step 5:
When dividing 4580 by 669, we get 6 with a remainder of 566.
Write down 6 as next digit of the result. 
Result so far: 56.0
Deduct 4014 from 4580 and we're left with 566.
Bring next digit (8) of the dividend behind the 566 and repeat the process: 5668 / 669

Going ahead to step 6:
669 can be fit into 5668 8 times, resulting in a remainder of 316.
Write down 8 as next digit of the result. 
Result so far: 568.0
If we subtract 5352 from 5668, we get 316.
Grab the next digit (4) from the dividend, add it to 316, then carry on: 3164 / 669

Advancing to step 7:
When dividing 3164 by 669, we get 4 with a remainder of 488.
Write down 4 as next digit of the result. 
Result so far: 5684.0
If we take 2676 away from 3164, we end up with 488.
Append the next digit (3) from the dividend to 488 and continue with: 4883 / 669

Step 8:
The number 669 fits into 4883 7 times, leaving a remainder of 200.
Use 7 as the next digit of our solution. 
Result so far: 56847.0
Subtract 4683 from 4883 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 9:
669 can be fit into 2000 2 times, resulting in a remainder of 662.
The next digit of our result is 2. 
Result so far: 56847.2
Subtract 1338 from 2000 to get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Moving on to step 10:
If we divide 6620 by 669, we get 9 and a remainder of 599.
The next digit of our result is 9. 
Result so far: 56847.29
If we subtract 6021 from 6620, we get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

On to step 11:
The number 669 fits into 5990 8 times, leaving a remainder of 638.
The number 8 becomes the next digit in our result. 
Result so far: 56847.298
The remainder is 638 after subtracting 5352 from 5990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

On to step 12:
669 can be fit into 6380 9 times, resulting in a remainder of 359.
Use 9 as the next digit of our solution. 
Result so far: 56847.2989
Subtracting 6021 from 6380 leaves us with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Going ahead to step 13:
If we divide 3590 by 669, we get 5 and a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 56847.29895
If we subtract 3345 from 3590, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 14:
When dividing 2450 by 669, we get 3 with a remainder of 443.
Use 3 as the next digit of our solution. 
Result so far: 56847.298953
If we subtract 2007 from 2450, we get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

On to step 15:
669 can be fit into 4430 6 times, resulting in a remainder of 416.
The number 6 becomes the next digit in our result. 
Result so far: 56847.2989536
The remainder is 416 after subtracting 4014 from 4430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 16:
If we divide 4160 by 669, we get 6 and a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 56847.29895366
Subtract 4014 from 4160 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

In conclusion, the division gives 56847.29895366 with a balance of 1.46e-07.
