We divide 308110 by 87
The aim is to understand the frequency of 87 in 308110.

Going ahead to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 87

On to step 2:
87 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 87

Step 3:
87 can be fit into 308 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 47 after subtracting 261 from 308.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 87

Going ahead to step 4:
471 divided by 87 is 5 with a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtracting 435 from 471 leaves us with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 87

Moving on to step 5:
361 divided by 87 is 4 with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 354.0
Deduct 348 from 361 and we're left with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 87

On to step 6:
When dividing 130 by 87, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 3541.0
If we take 87 away from 130, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
If we divide 430 by 87, we get 4 and a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 3541.4
Deduct 348 from 430 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 8:
The number 87 fits into 820 9 times, leaving a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 3541.49
Subtract 783 from 820 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
87 goes into 370 4 times with a remainder of 22.
The next digit of our result is 4. 
Result so far: 3541.494
If we subtract 348 from 370, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
The number 87 fits into 220 2 times, leaving a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 3541.4942
The remainder is 46 after subtracting 174 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
When dividing 460 by 87, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 3541.49425
The remainder is 25 after subtracting 435 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
87 goes into 250 2 times with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 3541.494252
Deduct 174 from 250 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 13:
760 divided by 87 is 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 3541.4942528
If we subtract 696 from 760, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
640 divided by 87 is 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 3541.49425287
If we subtract 609 from 640, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

After the division, we end up with 3541.49425287 and a remainder of 3.1e-08.
