325366 ÷ 87 
The aim is to understand the frequency of 87 in 325366.

Advancing to step 1:
87 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 87

Let's proceed to step 2:
If we divide 32 by 87, we get 0 and a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 32, we end up with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 87

Moving on to step 3:
87 goes into 325 3 times with a remainder of 64.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 261 away from 325, we end up with 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 87

Step 4:
87 goes into 643 7 times with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
The remainder is 34 after subtracting 609 from 643.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 87

Moving on to step 5:
The number 87 fits into 346 3 times, leaving a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 373.0
Subtract 261 from 346 to get 85.
Bring next digit (6) of the dividend behind the 85 and repeat the process: 856 / 87

Let's proceed to step 6:
The number 87 fits into 856 9 times, leaving a remainder of 73.
Record the quotient 9 as the next digit in the result. 
Result so far: 3739.0
If we take 783 away from 856, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 7:
The number 87 fits into 730 8 times, leaving a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 3739.8
If we take 696 away from 730, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
The number 87 fits into 340 3 times, leaving a remainder of 79.
The next digit of our result is 3. 
Result so far: 3739.83
If we subtract 261 from 340, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 9:
When dividing 790 by 87, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 3739.839
The remainder is 7 after subtracting 783 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
87 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 3739.839
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
When dividing 700 by 87, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 3739.83908
Deduct 696 from 700 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
When dividing 40 by 87, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 3739.83908
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
87 can be fit into 400 4 times, resulting in a remainder of 52.
The next digit of our result is 4. 
Result so far: 3739.8390804
If we subtract 348 from 400, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
When dividing 520 by 87, we get 5 with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 3739.83908045
If we subtract 435 from 520, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 3739.83908045 and a remainder of 8.5e-08.
