Let's divide 52378623 by 680
The aim is to understand the frequency of 680 in 52378623.

Advancing to step 1:
If we divide 5 by 680, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 680

Let's proceed to step 2:
680 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 680

Advancing to step 3:
If we divide 523 by 680, we get 0 and a remainder of 523.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 523 to get 523.
Grab the next digit (7) from the dividend, add it to 523, then carry on: 5237 / 680

Going ahead to step 4:
If we divide 5237 by 680, we get 7 and a remainder of 477.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 4760 from 5237 leaves us with 477.
Grab the next digit (8) from the dividend, add it to 477, then carry on: 4778 / 680

Step 5:
680 can be fit into 4778 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 4760 from 4778 leaves us with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 680

Let's proceed to step 6:
If we divide 186 by 680, we get 0 and a remainder of 186.
Record the quotient 0 as the next digit in the result. 
Result so far: 770.0
If we subtract 0 from 186, we get 186.
Append the next digit (2) from the dividend to 186 and continue with: 1862 / 680

Advancing to step 7:
The number 680 fits into 1862 2 times, leaving a remainder of 502.
Use 2 as the next digit of our solution. 
Result so far: 7702.0
The remainder is 502 after subtracting 1360 from 1862.
Grab the next digit (3) from the dividend, add it to 502, then carry on: 5023 / 680

On to step 8:
5023 divided by 680 is 7 with a remainder of 263.
Use 7 as the next digit of our solution. 
Result so far: 77027.0
If we take 4760 away from 5023, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 9:
When dividing 2630 by 680, we get 3 with a remainder of 590.
The next digit of our result is 3. 
Result so far: 77027.3
Subtracting 2040 from 2630 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 10:
680 can be fit into 5900 8 times, resulting in a remainder of 460.
Put 8 as the next digit of the answer. 
Result so far: 77027.38
The remainder is 460 after subtracting 5440 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 11:
If we divide 4600 by 680, we get 6 and a remainder of 520.
The number 6 becomes the next digit in our result. 
Result so far: 77027.386
Subtract 4080 from 4600 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 12:
680 can be fit into 5200 7 times, resulting in a remainder of 440.
Record the quotient 7 as the next digit in the result. 
Result so far: 77027.3867
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.

On to step 13:
680 can be fit into 4400 6 times, resulting in a remainder of 320.
Put 6 as the next digit of the answer. 
Result so far: 77027.38676
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.

Step 14:
3200 divided by 680 is 4 with a remainder of 480.
Put 4 as the next digit of the answer. 
Result so far: 77027.386764
Subtracting 2720 from 3200 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 15:
The number 680 fits into 4800 7 times, leaving a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 77027.3867647
Subtracting 4760 from 4800 leaves us 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.

Going ahead to step 16:
When dividing 400 by 680, we get 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 77027.3867647
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.

After the division, we end up with 77027.3867647 and a remainder of 4e-07.
