We're dividing 72597914 by 641 
The aim is to understand the frequency of 641 in 72597914.

On to step 1:
When dividing 7 by 641, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 641

Going ahead to step 2:
If we divide 72 by 641, we get 0 and a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Include the next digit (5) from the dividend after 72, then repeat: 725 / 641

Let's proceed to step 3:
If we divide 725 by 641, we get 1 and a remainder of 84.
The next digit of our result is 1. 
Result so far: 1.0
If we take 641 away from 725, we end up with 84.
Grab the next digit (9) from the dividend, add it to 84, then carry on: 849 / 641

Moving on to step 4:
When dividing 849 by 641, we get 1 with a remainder of 208.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 641 away from 849, we end up with 208.
Append the next digit (7) from the dividend to 208 and continue with: 2087 / 641

Going ahead to step 5:
When dividing 2087 by 641, we get 3 with a remainder of 164.
The next digit of our result is 3. 
Result so far: 113.0
If we subtract 1923 from 2087, we get 164.
Fetch the next digit (9) from the dividend, attach it to 164 and continue: 1649 / 641

Advancing to step 6:
If we divide 1649 by 641, we get 2 and a remainder of 367.
Write down 2 as next digit of the result. 
Result so far: 1132.0
Deduct 1282 from 1649 and we're left with 367.
Bring next digit (1) of the dividend behind the 367 and repeat the process: 3671 / 641

Step 7:
3671 divided by 641 is 5 with a remainder of 466.
Put 5 as the next digit of the answer. 
Result so far: 11325.0
Subtracting 3205 from 3671 leaves us with 466.
Fetch the next digit (4) from the dividend, attach it to 466 and continue: 4664 / 641

On to step 8:
641 can be fit into 4664 7 times, resulting in a remainder of 177.
The number 7 becomes the next digit in our result. 
Result so far: 113257.0
Deduct 4487 from 4664 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 9:
641 goes into 1770 2 times with a remainder of 488.
Use 2 as the next digit of our solution. 
Result so far: 113257.2
If we take 1282 away from 1770, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 10:
The number 641 fits into 4880 7 times, leaving a remainder of 393.
The next digit of our result is 7. 
Result so far: 113257.27
Deduct 4487 from 4880 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Advancing to step 11:
3930 divided by 641 is 6 with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 113257.276
Subtract 3846 from 3930 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 12:
When dividing 840 by 641, we get 1 with a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 113257.2761
If we take 641 away from 840, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 13:
1990 divided by 641 is 3 with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 113257.27613
Deduct 1923 from 1990 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 14:
The number 641 fits into 670 1 times, leaving a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 113257.276131
If we subtract 641 from 670, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 15:
If we divide 290 by 641, we get 0 and a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 113257.276131
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 16:
641 goes into 2900 4 times with a remainder of 336.
Record the quotient 4 as the next digit in the result. 
Result so far: 113257.27613104
If we subtract 2564 from 2900, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

After the division, we end up with 113257.27613104 and a remainder of 3.36e-07.
