We're dividing 50743027 by 640 
The aim is to understand the frequency of 640 in 50743027.

Moving on to step 1:
5 divided by 640 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 640

Advancing to step 2:
50 divided by 640 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Include the next digit (7) from the dividend after 50, then repeat: 507 / 640

Step 3:
If we divide 507 by 640, we get 0 and a remainder of 507.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 507, we get 507.
Take the next digit (4) from the dividend and append it to 507, then repeat: 5074 / 640

Advancing to step 4:
5074 divided by 640 is 7 with a remainder of 594.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 4480 from 5074, we get 594.
Fetch the next digit (3) from the dividend, attach it to 594 and continue: 5943 / 640

Advancing to step 5:
5943 divided by 640 is 9 with a remainder of 183.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
If we take 5760 away from 5943, we end up with 183.
Append the next digit (0) from the dividend to 183 and continue with: 1830 / 640

Going ahead to step 6:
When dividing 1830 by 640, we get 2 with a remainder of 550.
Put 2 as the next digit of the answer. 
Result so far: 792.0
Subtract 1280 from 1830 to get 550.
Bring next digit (2) of the dividend behind the 550 and repeat the process: 5502 / 640

Moving on to step 7:
640 can be fit into 5502 8 times, resulting in a remainder of 382.
The next digit of our result is 8. 
Result so far: 7928.0
If we take 5120 away from 5502, we end up with 382.
Bring next digit (7) of the dividend behind the 382 and repeat the process: 3827 / 640

Going ahead to step 8:
The number 640 fits into 3827 5 times, leaving a remainder of 627.
Put 5 as the next digit of the answer. 
Result so far: 79285.0
If we subtract 3200 from 3827, we get 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Step 9:
6270 divided by 640 is 9 with a remainder of 510.
Use 9 as the next digit of our solution. 
Result so far: 79285.9
If we subtract 5760 from 6270, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 10:
640 goes into 5100 7 times with a remainder of 620.
The next digit of our result is 7. 
Result so far: 79285.97
Subtracting 4480 from 5100 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 11:
When dividing 6200 by 640, we get 9 with a remainder of 440.
Write down 9 as next digit of the result. 
Result so far: 79285.979
If we take 5760 away from 6200, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 12:
The number 640 fits into 4400 6 times, leaving a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 79285.9796
Subtract 3840 from 4400 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
640 can be fit into 5600 8 times, resulting in a remainder of 480.
The next digit of our result is 8. 
Result so far: 79285.97968
If we subtract 5120 from 5600, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 14:
When dividing 4800 by 640, we get 7 with a remainder of 320.
The next digit of our result is 7. 
Result so far: 79285.979687
Subtract 4480 from 4800 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
When dividing 3200 by 640, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 79285.9796875
The remainder is 0 after subtracting 3200 from 3200.
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:
If we divide 0 by 640, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 79285.9796875
If we take 0 away from 0, we end up 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.

After the division, we end up with 79285.9796875 and a remainder of 0.0.
