89880496 divided by 687 
The aim is to understand the frequency of 687 in 89880496.

Let's proceed to step 1:
The number 687 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 687

Let's proceed to step 2:
If we divide 89 by 687, we get 0 and a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Bring next digit (8) of the dividend behind the 89 and repeat the process: 898 / 687

On to step 3:
687 goes into 898 1 times with a remainder of 211.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 687 from 898, we get 211.
Append the next digit (8) from the dividend to 211 and continue with: 2118 / 687

Let's proceed to step 4:
687 goes into 2118 3 times with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 2061 away from 2118, we end up with 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 687

Moving on to step 5:
570 divided by 687 is 0 with a remainder of 570.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Subtract 0 from 570 to get 570.
Include the next digit (4) from the dividend after 570, then repeat: 5704 / 687

Let's proceed to step 6:
When dividing 5704 by 687, we get 8 with a remainder of 208.
Record the quotient 8 as the next digit in the result. 
Result so far: 1308.0
Subtract 5496 from 5704 to get 208.
Fetch the next digit (9) from the dividend, attach it to 208 and continue: 2089 / 687

On to step 7:
687 goes into 2089 3 times with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 13083.0
If we subtract 2061 from 2089, we get 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 687

Let's proceed to step 8:
687 goes into 286 0 times with a remainder of 286.
The next digit of our result is 0. 
Result so far: 130830.0
Subtract 0 from 286 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 9:
If we divide 2860 by 687, we get 4 and a remainder of 112.
The number 4 becomes the next digit in our result. 
Result so far: 130830.4
The remainder is 112 after subtracting 2748 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 10:
The number 687 fits into 1120 1 times, leaving a remainder of 433.
The number 1 becomes the next digit in our result. 
Result so far: 130830.41
Subtract 687 from 1120 to get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Step 11:
4330 divided by 687 is 6 with a remainder of 208.
The next digit of our result is 6. 
Result so far: 130830.416
Deduct 4122 from 4330 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 12:
When dividing 2080 by 687, we get 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 130830.4163
If we subtract 2061 from 2080, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
When dividing 190 by 687, we get 0 with a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 130830.4163
Subtract 0 from 190 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 14:
The number 687 fits into 1900 2 times, leaving a remainder of 526.
Use 2 as the next digit of our solution. 
Result so far: 130830.416302
If we subtract 1374 from 1900, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Let's proceed to step 15:
687 goes into 5260 7 times with a remainder of 451.
Use 7 as the next digit of our solution. 
Result so far: 130830.4163027
If we subtract 4809 from 5260, we get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Advancing to step 16:
4510 divided by 687 is 6 with a remainder of 388.
Use 6 as the next digit of our solution. 
Result so far: 130830.41630276
Subtract 4122 from 4510 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

After the division, we end up with 130830.41630276 and a remainder of 3.88e-07.
