43865225 divided by 680 
The aim is to understand the frequency of 680 in 43865225.

Step 1:
The number 680 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 680

Step 2:
The number 680 fits into 43 0 times, leaving a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 680

Step 3:
680 can be fit into 438 0 times, resulting in a remainder of 438.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 438 and we're left with 438.
Append the next digit (6) from the dividend to 438 and continue with: 4386 / 680

Let's proceed to step 4:
680 can be fit into 4386 6 times, resulting in a remainder of 306.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 4080 from 4386 to get 306.
Fetch the next digit (5) from the dividend, attach it to 306 and continue: 3065 / 680

Advancing to step 5:
680 can be fit into 3065 4 times, resulting in a remainder of 345.
The next digit of our result is 4. 
Result so far: 64.0
The remainder is 345 after subtracting 2720 from 3065.
Take the next digit (2) from the dividend and append it to 345, then repeat: 3452 / 680

Going ahead to step 6:
If we divide 3452 by 680, we get 5 and a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 645.0
If we take 3400 away from 3452, we end up with 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 680

On to step 7:
680 can be fit into 522 0 times, resulting in a remainder of 522.
The next digit of our result is 0. 
Result so far: 6450.0
The remainder is 522 after subtracting 0 from 522.
Grab the next digit (5) from the dividend, add it to 522, then carry on: 5225 / 680

On to step 8:
680 goes into 5225 7 times with a remainder of 465.
Record the quotient 7 as the next digit in the result. 
Result so far: 64507.0
If we take 4760 away from 5225, we end up with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 9:
680 goes into 4650 6 times with a remainder of 570.
The number 6 becomes the next digit in our result. 
Result so far: 64507.6
If we subtract 4080 from 4650, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 10:
5700 divided by 680 is 8 with a remainder of 260.
Write down 8 as next digit of the result. 
Result so far: 64507.68
If we take 5440 away from 5700, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 11:
When dividing 2600 by 680, we get 3 with a remainder of 560.
Write down 3 as next digit of the result. 
Result so far: 64507.683
Subtract 2040 from 2600 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.

Let's proceed to step 12:
680 can be fit into 5600 8 times, resulting in a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 64507.6838
Deduct 5440 from 5600 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.

Going ahead to step 13:
680 can be fit into 1600 2 times, resulting in a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 64507.68382
The remainder is 240 after subtracting 1360 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
When dividing 2400 by 680, we get 3 with a remainder of 360.
Use 3 as the next digit of our solution. 
Result so far: 64507.683823
Subtract 2040 from 2400 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 15:
If we divide 3600 by 680, we get 5 and a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 64507.6838235
The remainder is 200 after subtracting 3400 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 16:
The number 680 fits into 2000 2 times, leaving a remainder of 640.
The number 2 becomes the next digit in our result. 
Result so far: 64507.68382352
Subtracting 1360 from 2000 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final outcome is 64507.68382352, with a leftover of 6.4e-07.
