38016899 ÷ 641 
The aim is to understand the frequency of 641 in 38016899.

Going ahead to step 1:
3 divided by 641 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 641

Let's proceed to step 2:
If we divide 38 by 641, we get 0 and a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 641

Moving on to step 3:
If we divide 380 by 641, we get 0 and a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 380 after subtracting 0 from 380.
Grab the next digit (1) from the dividend, add it to 380, then carry on: 3801 / 641

Step 4:
3801 divided by 641 is 5 with a remainder of 596.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 3205 from 3801 to get 596.
Bring next digit (6) of the dividend behind the 596 and repeat the process: 5966 / 641

Moving on to step 5:
When dividing 5966 by 641, we get 9 with a remainder of 197.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Deduct 5769 from 5966 and we're left with 197.
Include the next digit (8) from the dividend after 197, then repeat: 1978 / 641

Moving on to step 6:
641 goes into 1978 3 times with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 593.0
If we take 1923 away from 1978, we end up with 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 641

Step 7:
641 can be fit into 559 0 times, resulting in a remainder of 559.
Use 0 as the next digit of our solution. 
Result so far: 5930.0
If we subtract 0 from 559, we get 559.
Bring next digit (9) of the dividend behind the 559 and repeat the process: 5599 / 641

Moving on to step 8:
5599 divided by 641 is 8 with a remainder of 471.
Put 8 as the next digit of the answer. 
Result so far: 59308.0
If we take 5128 away from 5599, we end up with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Let's proceed to step 9:
641 goes into 4710 7 times with a remainder of 223.
The number 7 becomes the next digit in our result. 
Result so far: 59308.7
If we take 4487 away from 4710, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Let's proceed to step 10:
641 can be fit into 2230 3 times, resulting in a remainder of 307.
Use 3 as the next digit of our solution. 
Result so far: 59308.73
If we take 1923 away from 2230, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Moving on to step 11:
When dividing 3070 by 641, we get 4 with a remainder of 506.
The number 4 becomes the next digit in our result. 
Result so far: 59308.734
Deduct 2564 from 3070 and we're left with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Step 12:
If we divide 5060 by 641, we get 7 and a remainder of 573.
Write down 7 as next digit of the result. 
Result so far: 59308.7347
Subtract 4487 from 5060 to get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Advancing to step 13:
641 can be fit into 5730 8 times, resulting in a remainder of 602.
Put 8 as the next digit of the answer. 
Result so far: 59308.73478
If we subtract 5128 from 5730, we get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Moving on to step 14:
The number 641 fits into 6020 9 times, leaving a remainder of 251.
Put 9 as the next digit of the answer. 
Result so far: 59308.734789
Deduct 5769 from 6020 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 15:
If we divide 2510 by 641, we get 3 and a remainder of 587.
Use 3 as the next digit of our solution. 
Result so far: 59308.7347893
If we subtract 1923 from 2510, we get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Let's proceed to step 16:
641 can be fit into 5870 9 times, resulting in a remainder of 101.
Put 9 as the next digit of the answer. 
Result so far: 59308.73478939
Subtracting 5769 from 5870 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

In conclusion, the division gives 59308.73478939 with a balance of 1.01e-07.
