Let's divide 72499580 by 687
The aim is to understand the frequency of 687 in 72499580.

Let's proceed to step 1:
If we divide 7 by 687, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 687

Let's proceed to step 2:
When dividing 72 by 687, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 687

Moving on to step 3:
When dividing 724 by 687, we get 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 687 from 724 and we're left with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 687

Advancing to step 4:
If we divide 379 by 687, we get 0 and a remainder of 379.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 379 leaves us with 379.
Bring next digit (9) of the dividend behind the 379 and repeat the process: 3799 / 687

Step 5:
3799 divided by 687 is 5 with a remainder of 364.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtracting 3435 from 3799 leaves us with 364.
Grab the next digit (5) from the dividend, add it to 364, then carry on: 3645 / 687

Advancing to step 6:
687 goes into 3645 5 times with a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 1055.0
Subtract 3435 from 3645 to get 210.
Include the next digit (8) from the dividend after 210, then repeat: 2108 / 687

Let's proceed to step 7:
When dividing 2108 by 687, we get 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 10553.0
The remainder is 47 after subtracting 2061 from 2108.
Take the next digit (0) from the dividend and append it to 47, then repeat: 470 / 687

Let's proceed to step 8:
If we divide 470 by 687, we get 0 and a remainder of 470.
The next digit of our result is 0. 
Result so far: 105530.0
If we subtract 0 from 470, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 9:
If we divide 4700 by 687, we get 6 and a remainder of 578.
The number 6 becomes the next digit in our result. 
Result so far: 105530.6
If we subtract 4122 from 4700, we get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Let's proceed to step 10:
The number 687 fits into 5780 8 times, leaving a remainder of 284.
The number 8 becomes the next digit in our result. 
Result so far: 105530.68
Deduct 5496 from 5780 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 11:
The number 687 fits into 2840 4 times, leaving a remainder of 92.
Put 4 as the next digit of the answer. 
Result so far: 105530.684
Deduct 2748 from 2840 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 12:
920 divided by 687 is 1 with a remainder of 233.
Write down 1 as next digit of the result. 
Result so far: 105530.6841
If we take 687 away from 920, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 13:
When dividing 2330 by 687, we get 3 with a remainder of 269.
Write down 3 as next digit of the result. 
Result so far: 105530.68413
The remainder is 269 after subtracting 2061 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Let's proceed to step 14:
2690 divided by 687 is 3 with a remainder of 629.
The number 3 becomes the next digit in our result. 
Result so far: 105530.684133
If we take 2061 away from 2690, we end up with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Our division results in 105530.684133 with a remaining 6.29e-05.
