64089226 divided by 905 
The aim is to understand the frequency of 905 in 64089226.

Let's proceed to step 1:
If we divide 6 by 905, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 905

Going ahead to step 2:
905 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 905

Advancing to step 3:
When dividing 640 by 905, we get 0 with a remainder of 640.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 640 after subtracting 0 from 640.
Grab the next digit (8) from the dividend, add it to 640, then carry on: 6408 / 905

Advancing to step 4:
6408 divided by 905 is 7 with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 6335 away from 6408, we end up with 73.
Append the next digit (9) from the dividend to 73 and continue with: 739 / 905

Step 5:
The number 905 fits into 739 0 times, leaving a remainder of 739.
Write down 0 as next digit of the result. 
Result so far: 70.0
Subtract 0 from 739 to get 739.
Take the next digit (2) from the dividend and append it to 739, then repeat: 7392 / 905

Step 6:
The number 905 fits into 7392 8 times, leaving a remainder of 152.
The number 8 becomes the next digit in our result. 
Result so far: 708.0
Deduct 7240 from 7392 and we're left with 152.
Include the next digit (2) from the dividend after 152, then repeat: 1522 / 905

Let's proceed to step 7:
905 goes into 1522 1 times with a remainder of 617.
The next digit of our result is 1. 
Result so far: 7081.0
If we subtract 905 from 1522, we get 617.
Fetch the next digit (6) from the dividend, attach it to 617 and continue: 6176 / 905

Going ahead to step 8:
When dividing 6176 by 905, we get 6 with a remainder of 746.
Record the quotient 6 as the next digit in the result. 
Result so far: 70816.0
If we take 5430 away from 6176, we end up with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

On to step 9:
If we divide 7460 by 905, we get 8 and a remainder of 220.
Use 8 as the next digit of our solution. 
Result so far: 70816.8
Subtract 7240 from 7460 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
905 can be fit into 2200 2 times, resulting in a remainder of 390.
Write down 2 as next digit of the result. 
Result so far: 70816.82
Subtracting 1810 from 2200 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 11:
The number 905 fits into 3900 4 times, leaving a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 70816.824
Deduct 3620 from 3900 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 12:
When dividing 2800 by 905, we get 3 with a remainder of 85.
Put 3 as the next digit of the answer. 
Result so far: 70816.8243
If we take 2715 away from 2800, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 13:
905 can be fit into 850 0 times, resulting in a remainder of 850.
The number 0 becomes the next digit in our result. 
Result so far: 70816.8243
Deduct 0 from 850 and we're left with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Moving on to step 14:
8500 divided by 905 is 9 with a remainder of 355.
The number 9 becomes the next digit in our result. 
Result so far: 70816.824309
Subtracting 8145 from 8500 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 15:
905 can be fit into 3550 3 times, resulting in a remainder of 835.
The next digit of our result is 3. 
Result so far: 70816.8243093
If we take 2715 away from 3550, we end up with 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Moving on to step 16:
The number 905 fits into 8350 9 times, leaving a remainder of 205.
The next digit of our result is 9. 
Result so far: 70816.82430939
If we subtract 8145 from 8350, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The final result is 70816.82430939 with a remainder of 2.05e-07.
