We divide 87671300 by 685
The aim is to understand the frequency of 685 in 87671300.

Step 1:
If we divide 8 by 685, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 685

Step 2:
When dividing 87 by 685, we get 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Append the next digit (6) from the dividend to 87 and continue with: 876 / 685

Going ahead to step 3:
When dividing 876 by 685, we get 1 with a remainder of 191.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 685 from 876, we get 191.
Append the next digit (7) from the dividend to 191 and continue with: 1917 / 685

Advancing to step 4:
The number 685 fits into 1917 2 times, leaving a remainder of 547.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 547 after subtracting 1370 from 1917.
Grab the next digit (1) from the dividend, add it to 547, then carry on: 5471 / 685

Moving on to step 5:
If we divide 5471 by 685, we get 7 and a remainder of 676.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Deduct 4795 from 5471 and we're left with 676.
Append the next digit (3) from the dividend to 676 and continue with: 6763 / 685

On to step 6:
If we divide 6763 by 685, we get 9 and a remainder of 598.
The next digit of our result is 9. 
Result so far: 1279.0
The remainder is 598 after subtracting 6165 from 6763.
Append the next digit (0) from the dividend to 598 and continue with: 5980 / 685

Step 7:
If we divide 5980 by 685, we get 8 and a remainder of 500.
Record the quotient 8 as the next digit in the result. 
Result so far: 12798.0
Subtract 5480 from 5980 to get 500.
Fetch the next digit (0) from the dividend, attach it to 500 and continue: 5000 / 685

On to step 8:
685 can be fit into 5000 7 times, resulting in a remainder of 205.
Write down 7 as next digit of the result. 
Result so far: 127987.0
The remainder is 205 after subtracting 4795 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 9:
685 goes into 2050 2 times with a remainder of 680.
Record the quotient 2 as the next digit in the result. 
Result so far: 127987.2
Subtract 1370 from 2050 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 10:
6800 divided by 685 is 9 with a remainder of 635.
Use 9 as the next digit of our solution. 
Result so far: 127987.29
The remainder is 635 after subtracting 6165 from 6800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Moving on to step 11:
6350 divided by 685 is 9 with a remainder of 185.
The next digit of our result is 9. 
Result so far: 127987.299
If we subtract 6165 from 6350, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

In conclusion, the division gives 127987.299 with a balance of 0.0185.
