Let's divide 72639338 by 680
The aim is to understand the frequency of 680 in 72639338.

Let's proceed to step 1:
When dividing 7 by 680, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 680

On to step 2:
680 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Take the next digit (6) from the dividend and append it to 72, then repeat: 726 / 680

Step 3:
680 can be fit into 726 1 times, resulting in a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 680 away from 726, we end up with 46.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 680

Moving on to step 4:
The number 680 fits into 463 0 times, leaving a remainder of 463.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 463 leaves us with 463.
Bring next digit (9) of the dividend behind the 463 and repeat the process: 4639 / 680

Moving on to step 5:
If we divide 4639 by 680, we get 6 and a remainder of 559.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
If we take 4080 away from 4639, we end up with 559.
Grab the next digit (3) from the dividend, add it to 559, then carry on: 5593 / 680

On to step 6:
If we divide 5593 by 680, we get 8 and a remainder of 153.
Record the quotient 8 as the next digit in the result. 
Result so far: 1068.0
If we take 5440 away from 5593, we end up with 153.
Append the next digit (3) from the dividend to 153 and continue with: 1533 / 680

Advancing to step 7:
1533 divided by 680 is 2 with a remainder of 173.
Write down 2 as next digit of the result. 
Result so far: 10682.0
If we take 1360 away from 1533, we end up with 173.
Append the next digit (8) from the dividend to 173 and continue with: 1738 / 680

Going ahead to step 8:
When dividing 1738 by 680, we get 2 with a remainder of 378.
The next digit of our result is 2. 
Result so far: 106822.0
The remainder is 378 after subtracting 1360 from 1738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 9:
680 can be fit into 3780 5 times, resulting in a remainder of 380.
Write down 5 as next digit of the result. 
Result so far: 106822.5
Subtract 3400 from 3780 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 10:
680 can be fit into 3800 5 times, resulting in a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 106822.55
The remainder is 400 after subtracting 3400 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 106822.55, and the remainder is 0.4.
