53922222 ÷ 640 
The aim is to understand the frequency of 640 in 53922222.

Step 1:
5 divided by 640 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 640

On to step 2:
The number 640 fits into 53 0 times, leaving a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 640

Moving on to step 3:
640 goes into 539 0 times with a remainder of 539.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 539 to get 539.
Fetch the next digit (2) from the dividend, attach it to 539 and continue: 5392 / 640

Let's proceed to step 4:
640 goes into 5392 8 times with a remainder of 272.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 5120 from 5392, we get 272.
Append the next digit (2) from the dividend to 272 and continue with: 2722 / 640

Going ahead to step 5:
2722 divided by 640 is 4 with a remainder of 162.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 162 after subtracting 2560 from 2722.
Grab the next digit (2) from the dividend, add it to 162, then carry on: 1622 / 640

Moving on to step 6:
1622 divided by 640 is 2 with a remainder of 342.
Put 2 as the next digit of the answer. 
Result so far: 842.0
If we subtract 1280 from 1622, we get 342.
Grab the next digit (2) from the dividend, add it to 342, then carry on: 3422 / 640

Moving on to step 7:
640 goes into 3422 5 times with a remainder of 222.
Put 5 as the next digit of the answer. 
Result so far: 8425.0
The remainder is 222 after subtracting 3200 from 3422.
Include the next digit (2) from the dividend after 222, then repeat: 2222 / 640

Moving on to step 8:
640 can be fit into 2222 3 times, resulting in a remainder of 302.
Put 3 as the next digit of the answer. 
Result so far: 84253.0
Subtract 1920 from 2222 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 9:
640 can be fit into 3020 4 times, resulting in a remainder of 460.
Use 4 as the next digit of our solution. 
Result so far: 84253.4
If we take 2560 away from 3020, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 10:
4600 divided by 640 is 7 with a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 84253.47
Deduct 4480 from 4600 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 11:
1200 divided by 640 is 1 with a remainder of 560.
Record the quotient 1 as the next digit in the result. 
Result so far: 84253.471
If we subtract 640 from 1200, we 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.

On to step 12:
640 goes into 5600 8 times with a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 84253.4718
Deduct 5120 from 5600 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 13:
If we divide 4800 by 640, we get 7 and a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 84253.47187
The remainder is 320 after subtracting 4480 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 14:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 84253.471875
If we subtract 3200 from 3200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 15:
If we divide 0 by 640, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 84253.471875
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.

Step 16:
When dividing 0 by 640, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 84253.471875
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 84253.471875 and a remainder of 0.0.
