80503814 divided by 680 
The aim is to understand the frequency of 680 in 80503814.

Let's proceed to step 1:
680 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.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 680

Advancing to step 2:
680 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (5) of the dividend behind the 80 and repeat the process: 805 / 680

On to step 3:
805 divided by 680 is 1 with a remainder of 125.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 125 after subtracting 680 from 805.
Include the next digit (0) from the dividend after 125, then repeat: 1250 / 680

Let's proceed to step 4:
When dividing 1250 by 680, we get 1 with a remainder of 570.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 680 from 1250, we get 570.
Grab the next digit (3) from the dividend, add it to 570, then carry on: 5703 / 680

Step 5:
5703 divided by 680 is 8 with a remainder of 263.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Deduct 5440 from 5703 and we're left with 263.
Fetch the next digit (8) from the dividend, attach it to 263 and continue: 2638 / 680

Step 6:
680 goes into 2638 3 times with a remainder of 598.
Write down 3 as next digit of the result. 
Result so far: 1183.0
If we take 2040 away from 2638, we end up with 598.
Include the next digit (1) from the dividend after 598, then repeat: 5981 / 680

Moving on to step 7:
5981 divided by 680 is 8 with a remainder of 541.
Record the quotient 8 as the next digit in the result. 
Result so far: 11838.0
Subtract 5440 from 5981 to get 541.
Append the next digit (4) from the dividend to 541 and continue with: 5414 / 680

Step 8:
When dividing 5414 by 680, we get 7 with a remainder of 654.
Record the quotient 7 as the next digit in the result. 
Result so far: 118387.0
Deduct 4760 from 5414 and we're left with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Let's proceed to step 9:
If we divide 6540 by 680, we get 9 and a remainder of 420.
Write down 9 as next digit of the result. 
Result so far: 118387.9
If we subtract 6120 from 6540, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 10:
The number 680 fits into 4200 6 times, leaving a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 118387.96
If we subtract 4080 from 4200, we 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.

On to step 11:
When dividing 1200 by 680, we get 1 with a remainder of 520.
The next digit of our result is 1. 
Result so far: 118387.961
If we take 680 away from 1200, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 12:
When dividing 5200 by 680, we get 7 with a remainder of 440.
The next digit of our result is 7. 
Result so far: 118387.9617
Deduct 4760 from 5200 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 13:
If we divide 4400 by 680, we get 6 and a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 118387.96176
The remainder is 320 after subtracting 4080 from 4400.
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 14:
The number 680 fits into 3200 4 times, leaving a remainder of 480.
Put 4 as the next digit of the answer. 
Result so far: 118387.961764
Deduct 2720 from 3200 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.

Step 15:
680 can be fit into 4800 7 times, resulting in a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 118387.9617647
Subtract 4760 from 4800 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
400 divided by 680 is 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 118387.9617647
Subtracting 0 from 400 leaves us 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.

The final outcome is 118387.9617647, with a leftover of 4e-07.
