We look at the division of 83793719 by 640 
The aim is to understand the frequency of 640 in 83793719.

Moving on to step 1:
640 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 640

Step 2:
When dividing 83 by 640, we get 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Include the next digit (7) from the dividend after 83, then repeat: 837 / 640

Moving on to step 3:
640 goes into 837 1 times with a remainder of 197.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 640 away from 837, we end up with 197.
Bring next digit (9) of the dividend behind the 197 and repeat the process: 1979 / 640

Going ahead to step 4:
The number 640 fits into 1979 3 times, leaving a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 59 after subtracting 1920 from 1979.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 640

Let's proceed to step 5:
593 divided by 640 is 0 with a remainder of 593.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Deduct 0 from 593 and we're left with 593.
Grab the next digit (7) from the dividend, add it to 593, then carry on: 5937 / 640

Step 6:
640 goes into 5937 9 times with a remainder of 177.
The number 9 becomes the next digit in our result. 
Result so far: 1309.0
If we take 5760 away from 5937, we end up with 177.
Append the next digit (1) from the dividend to 177 and continue with: 1771 / 640

Step 7:
If we divide 1771 by 640, we get 2 and a remainder of 491.
The next digit of our result is 2. 
Result so far: 13092.0
If we subtract 1280 from 1771, we get 491.
Bring next digit (9) of the dividend behind the 491 and repeat the process: 4919 / 640

Advancing to step 8:
640 goes into 4919 7 times with a remainder of 439.
Put 7 as the next digit of the answer. 
Result so far: 130927.0
If we subtract 4480 from 4919, we get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Going ahead to step 9:
If we divide 4390 by 640, we get 6 and a remainder of 550.
Write down 6 as next digit of the result. 
Result so far: 130927.6
If we take 3840 away from 4390, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 10:
When dividing 5500 by 640, we get 8 with a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 130927.68
Deduct 5120 from 5500 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 11:
640 can be fit into 3800 5 times, resulting in a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 130927.685
The remainder is 600 after subtracting 3200 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
The number 640 fits into 6000 9 times, leaving a remainder of 240.
Write down 9 as next digit of the result. 
Result so far: 130927.6859
If we take 5760 away from 6000, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
640 goes into 2400 3 times with a remainder of 480.
The next digit of our result is 3. 
Result so far: 130927.68593
Subtracting 1920 from 2400 leaves us 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.

Step 14:
The number 640 fits into 4800 7 times, leaving a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 130927.685937
Subtracting 4480 from 4800 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 15:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 130927.6859375
Subtract 3200 from 3200 to 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.

Going ahead to step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 130927.6859375
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 130927.6859375 with a remainder of 0.0.
