69475154 divided by 641 
The aim is to understand the frequency of 641 in 69475154.

Going ahead to step 1:
6 divided by 641 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 641

On to step 2:
When dividing 69 by 641, we get 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Include the next digit (4) from the dividend after 69, then repeat: 694 / 641

Advancing to step 3:
The number 641 fits into 694 1 times, leaving a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 641 away from 694, we end up with 53.
Bring next digit (7) of the dividend behind the 53 and repeat the process: 537 / 641

Step 4:
When dividing 537 by 641, we get 0 with a remainder of 537.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 537 after subtracting 0 from 537.
Grab the next digit (5) from the dividend, add it to 537, then carry on: 5375 / 641

On to step 5:
If we divide 5375 by 641, we get 8 and a remainder of 247.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtract 5128 from 5375 to get 247.
Fetch the next digit (1) from the dividend, attach it to 247 and continue: 2471 / 641

Let's proceed to step 6:
641 can be fit into 2471 3 times, resulting in a remainder of 548.
Write down 3 as next digit of the result. 
Result so far: 1083.0
The remainder is 548 after subtracting 1923 from 2471.
Bring next digit (5) of the dividend behind the 548 and repeat the process: 5485 / 641

Advancing to step 7:
641 can be fit into 5485 8 times, resulting in a remainder of 357.
The number 8 becomes the next digit in our result. 
Result so far: 10838.0
Subtract 5128 from 5485 to get 357.
Append the next digit (4) from the dividend to 357 and continue with: 3574 / 641

Let's proceed to step 8:
If we divide 3574 by 641, we get 5 and a remainder of 369.
Put 5 as the next digit of the answer. 
Result so far: 108385.0
If we take 3205 away from 3574, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 9:
3690 divided by 641 is 5 with a remainder of 485.
The number 5 becomes the next digit in our result. 
Result so far: 108385.5
Deduct 3205 from 3690 and we're left with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Going ahead to step 10:
4850 divided by 641 is 7 with a remainder of 363.
Write down 7 as next digit of the result. 
Result so far: 108385.57
Deduct 4487 from 4850 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Moving on to step 11:
When dividing 3630 by 641, we get 5 with a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 108385.575
Subtract 3205 from 3630 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 12:
641 can be fit into 4250 6 times, resulting in a remainder of 404.
Use 6 as the next digit of our solution. 
Result so far: 108385.5756
Subtracting 3846 from 4250 leaves us 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.

On to step 13:
641 goes into 4040 6 times with a remainder of 194.
The next digit of our result is 6. 
Result so far: 108385.57566
If we take 3846 away from 4040, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Our division results in 108385.57566 with a remaining 0.000194.
