39788345 divided by 640 
The aim is to understand the frequency of 640 in 39788345.

Advancing to step 1:
640 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 640

Advancing to step 2:
When dividing 39 by 640, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 640

Moving on to step 3:
The number 640 fits into 397 0 times, leaving a remainder of 397.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 397, we get 397.
Grab the next digit (8) from the dividend, add it to 397, then carry on: 3978 / 640

Let's proceed to step 4:
640 goes into 3978 6 times with a remainder of 138.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 3840 from 3978 and we're left with 138.
Bring next digit (8) of the dividend behind the 138 and repeat the process: 1388 / 640

Going ahead to step 5:
The number 640 fits into 1388 2 times, leaving a remainder of 108.
Put 2 as the next digit of the answer. 
Result so far: 62.0
The remainder is 108 after subtracting 1280 from 1388.
Include the next digit (3) from the dividend after 108, then repeat: 1083 / 640

Moving on to step 6:
If we divide 1083 by 640, we get 1 and a remainder of 443.
The number 1 becomes the next digit in our result. 
Result so far: 621.0
Deduct 640 from 1083 and we're left with 443.
Include the next digit (4) from the dividend after 443, then repeat: 4434 / 640

Step 7:
When dividing 4434 by 640, we get 6 with a remainder of 594.
Write down 6 as next digit of the result. 
Result so far: 6216.0
If we take 3840 away from 4434, we end up with 594.
Take the next digit (5) from the dividend and append it to 594, then repeat: 5945 / 640

Going ahead to step 8:
If we divide 5945 by 640, we get 9 and a remainder of 185.
The next digit of our result is 9. 
Result so far: 62169.0
If we take 5760 away from 5945, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 9:
The number 640 fits into 1850 2 times, leaving a remainder of 570.
Write down 2 as next digit of the result. 
Result so far: 62169.2
If we take 1280 away from 1850, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 10:
640 can be fit into 5700 8 times, resulting in a remainder of 580.
Put 8 as the next digit of the answer. 
Result so far: 62169.28
If we subtract 5120 from 5700, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 11:
When dividing 5800 by 640, we get 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 62169.289
Deduct 5760 from 5800 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
400 divided by 640 is 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 62169.289
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 13:
When dividing 4000 by 640, we get 6 with a remainder of 160.
The next digit of our result is 6. 
Result so far: 62169.28906
Deduct 3840 from 4000 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
The number 640 fits into 1600 2 times, leaving a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 62169.289062
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.

On to step 15:
When dividing 3200 by 640, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 62169.2890625
If we take 3200 away from 3200, 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.

Advancing to step 16:
If we divide 0 by 640, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 62169.2890625
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.

After the division, we end up with 62169.2890625 and a remainder of 0.0.
