33127743 divided by 641 
The aim is to understand the frequency of 641 in 33127743.

On to step 1:
When dividing 3 by 641, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 641

Step 2:
641 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 641

Let's proceed to step 3:
641 can be fit into 331 0 times, resulting in a remainder of 331.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 331 to get 331.
Bring next digit (2) of the dividend behind the 331 and repeat the process: 3312 / 641

On to step 4:
641 goes into 3312 5 times with a remainder of 107.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 3205 away from 3312, we end up with 107.
Fetch the next digit (7) from the dividend, attach it to 107 and continue: 1077 / 641

Advancing to step 5:
641 goes into 1077 1 times with a remainder of 436.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 641 from 1077, we get 436.
Include the next digit (7) from the dividend after 436, then repeat: 4367 / 641

Going ahead to step 6:
When dividing 4367 by 641, we get 6 with a remainder of 521.
The next digit of our result is 6. 
Result so far: 516.0
Subtract 3846 from 4367 to get 521.
Append the next digit (4) from the dividend to 521 and continue with: 5214 / 641

On to step 7:
641 goes into 5214 8 times with a remainder of 86.
Use 8 as the next digit of our solution. 
Result so far: 5168.0
Subtract 5128 from 5214 to get 86.
Take the next digit (3) from the dividend and append it to 86, then repeat: 863 / 641

On to step 8:
641 goes into 863 1 times with a remainder of 222.
The next digit of our result is 1. 
Result so far: 51681.0
Subtract 641 from 863 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 9:
If we divide 2220 by 641, we get 3 and a remainder of 297.
Use 3 as the next digit of our solution. 
Result so far: 51681.3
If we subtract 1923 from 2220, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 10:
641 goes into 2970 4 times with a remainder of 406.
The next digit of our result is 4. 
Result so far: 51681.34
If we subtract 2564 from 2970, we get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 11:
641 can be fit into 4060 6 times, resulting in a remainder of 214.
Use 6 as the next digit of our solution. 
Result so far: 51681.346
If we take 3846 away from 4060, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 12:
641 can be fit into 2140 3 times, resulting in a remainder of 217.
The number 3 becomes the next digit in our result. 
Result so far: 51681.3463
If we subtract 1923 from 2140, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Going ahead to step 13:
When dividing 2170 by 641, we get 3 with a remainder of 247.
Put 3 as the next digit of the answer. 
Result so far: 51681.34633
If we subtract 1923 from 2170, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

The final result is 51681.34633 with a remainder of 0.000247.
