Let's divide 620116 by 640
The aim is to understand the frequency of 640 in 620116.

Going ahead to step 1:
The number 640 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 640

Moving on to step 2:
If we divide 62 by 640, we get 0 and a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 640

On to step 3:
620 divided by 640 is 0 with a remainder of 620.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 620 after subtracting 0 from 620.
Include the next digit (1) from the dividend after 620, then repeat: 6201 / 640

Moving on to step 4:
If we divide 6201 by 640, we get 9 and a remainder of 441.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 5760 from 6201, we get 441.
Fetch the next digit (1) from the dividend, attach it to 441 and continue: 4411 / 640

Moving on to step 5:
The number 640 fits into 4411 6 times, leaving a remainder of 571.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we subtract 3840 from 4411, we get 571.
Bring next digit (6) of the dividend behind the 571 and repeat the process: 5716 / 640

Step 6:
When dividing 5716 by 640, we get 8 with a remainder of 596.
The number 8 becomes the next digit in our result. 
Result so far: 968.0
If we take 5120 away from 5716, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Moving on to step 7:
5960 divided by 640 is 9 with a remainder of 200.
Write down 9 as next digit of the result. 
Result so far: 968.9
If we subtract 5760 from 5960, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 8:
640 goes into 2000 3 times with a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 968.93
If we take 1920 away from 2000, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
640 goes into 800 1 times with a remainder of 160.
Write down 1 as next digit of the result. 
Result so far: 968.931
The remainder is 160 after subtracting 640 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
If we divide 1600 by 640, we get 2 and a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 968.9312
Deduct 1280 from 1600 and we're left 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.

Step 11:
If we divide 3200 by 640, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 968.93125
Subtracting 3200 from 3200 leaves us 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.

Let's proceed to step 12:
0 divided by 640 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 968.93125
Subtracting 0 from 0 leaves us 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 13:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 968.93125
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 968.93125, and the remainder is 0.0.
