294071 divided by 87 
The aim is to understand the frequency of 87 in 294071.

Advancing to step 1:
The number 87 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 87

Let's proceed to step 2:
When dividing 29 by 87, we get 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 87

Moving on to step 3:
87 goes into 294 3 times with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 261 from 294 to get 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 87

Moving on to step 4:
330 divided by 87 is 3 with a remainder of 69.
The next digit of our result is 3. 
Result so far: 33.0
Subtract 261 from 330 to get 69.
Append the next digit (7) from the dividend to 69 and continue with: 697 / 87

Step 5:
When dividing 697 by 87, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 338.0
Subtract 696 from 697 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 87

Let's proceed to step 6:
The number 87 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 3380.0
If we take 0 away from 11, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
The number 87 fits into 110 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 3380.1
Subtract 87 from 110 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
230 divided by 87 is 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 3380.12
Deduct 174 from 230 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
The number 87 fits into 560 6 times, leaving a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 3380.126
Subtract 522 from 560 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
If we divide 380 by 87, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 3380.1264
If we subtract 348 from 380, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
87 goes into 320 3 times with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 3380.12643
Deduct 261 from 320 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 12:
87 can be fit into 590 6 times, resulting in a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 3380.126436
If we take 522 away from 590, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 13:
The number 87 fits into 680 7 times, leaving a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 3380.1264367
Subtracting 609 from 680 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 14:
87 can be fit into 710 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 3380.12643678
Deduct 696 from 710 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 3380.12643678, with a leftover of 1.4e-08.
