73676814 ÷ 640 
The aim is to understand the frequency of 640 in 73676814.

Moving on to step 1:
640 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 640

On to step 2:
If we divide 73 by 640, we get 0 and a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 640

Moving on to step 3:
If we divide 736 by 640, we get 1 and a remainder of 96.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 640 from 736 leaves us with 96.
Fetch the next digit (7) from the dividend, attach it to 96 and continue: 967 / 640

Moving on to step 4:
640 goes into 967 1 times with a remainder of 327.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 640 from 967, we get 327.
Include the next digit (6) from the dividend after 327, then repeat: 3276 / 640

Let's proceed to step 5:
640 goes into 3276 5 times with a remainder of 76.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtracting 3200 from 3276 leaves us with 76.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 640

On to step 6:
768 divided by 640 is 1 with a remainder of 128.
The next digit of our result is 1. 
Result so far: 1151.0
If we subtract 640 from 768, we get 128.
Grab the next digit (1) from the dividend, add it to 128, then carry on: 1281 / 640

On to step 7:
The number 640 fits into 1281 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 11512.0
Deduct 1280 from 1281 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 640

Step 8:
640 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 115120.0
The remainder is 14 after subtracting 0 from 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
140 divided by 640 is 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 115120.0
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
When dividing 1400 by 640, we get 2 with a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 115120.02
Subtract 1280 from 1400 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
640 can be fit into 1200 1 times, resulting in a remainder of 560.
Use 1 as the next digit of our solution. 
Result so far: 115120.021
Subtract 640 from 1200 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 12:
If we divide 5600 by 640, we get 8 and a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 115120.0218
Subtracting 5120 from 5600 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 13:
640 can be fit into 4800 7 times, resulting in a remainder of 320.
Use 7 as the next digit of our solution. 
Result so far: 115120.02187
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.

Let's proceed to step 14:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 115120.021875
Deduct 3200 from 3200 and we're left 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.

Going ahead to step 15:
When dividing 0 by 640, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 115120.021875
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.

Step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 115120.021875
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.

Our division results in 115120.021875 with a remaining 0.0.
