We're dividing 26307633 by 640 
The aim is to understand the frequency of 640 in 26307633.

Going ahead to step 1:
640 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 640

Going ahead to step 2:
26 divided by 640 is 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 640

Moving on to step 3:
The number 640 fits into 263 0 times, leaving a remainder of 263.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 263 and we're left with 263.
Include the next digit (0) from the dividend after 263, then repeat: 2630 / 640

Going ahead to step 4:
When dividing 2630 by 640, we get 4 with a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 2560 from 2630 and we're left with 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 640

Let's proceed to step 5:
The number 640 fits into 707 1 times, leaving a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Deduct 640 from 707 and we're left with 67.
Fetch the next digit (6) from the dividend, attach it to 67 and continue: 676 / 640

On to step 6:
676 divided by 640 is 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 411.0
The remainder is 36 after subtracting 640 from 676.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 640

Going ahead to step 7:
363 divided by 640 is 0 with a remainder of 363.
Record the quotient 0 as the next digit in the result. 
Result so far: 4110.0
Subtracting 0 from 363 leaves us with 363.
Bring next digit (3) of the dividend behind the 363 and repeat the process: 3633 / 640

On to step 8:
If we divide 3633 by 640, we get 5 and a remainder of 433.
Write down 5 as next digit of the result. 
Result so far: 41105.0
If we take 3200 away from 3633, we end up with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Going ahead to step 9:
640 goes into 4330 6 times with a remainder of 490.
Use 6 as the next digit of our solution. 
Result so far: 41105.6
If we subtract 3840 from 4330, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 10:
The number 640 fits into 4900 7 times, leaving a remainder of 420.
Put 7 as the next digit of the answer. 
Result so far: 41105.67
Deduct 4480 from 4900 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 11:
When dividing 4200 by 640, we get 6 with a remainder of 360.
The number 6 becomes the next digit in our result. 
Result so far: 41105.676
The remainder is 360 after subtracting 3840 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 12:
3600 divided by 640 is 5 with a remainder of 400.
Put 5 as the next digit of the answer. 
Result so far: 41105.6765
The remainder is 400 after subtracting 3200 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
4000 divided by 640 is 6 with a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 41105.67656
If we subtract 3840 from 4000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
When dividing 1600 by 640, we get 2 with a remainder of 320.
Use 2 as the next digit of our solution. 
Result so far: 41105.676562
The remainder is 320 after subtracting 1280 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 15:
When dividing 3200 by 640, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 41105.6765625
Deduct 3200 from 3200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 16:
When dividing 0 by 640, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41105.6765625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 41105.6765625 with a remainder of 0.0.
