259309 ÷ 87 
The aim is to understand the frequency of 87 in 259309.

Moving on to step 1:
87 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 87

Advancing to step 2:
The number 87 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 87

On to step 3:
87 goes into 259 2 times with a remainder of 85.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 85 after subtracting 174 from 259.
Grab the next digit (3) from the dividend, add it to 85, then carry on: 853 / 87

Let's proceed to step 4:
87 can be fit into 853 9 times, resulting in a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 783 from 853 leaves us with 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 87

Advancing to step 5:
The number 87 fits into 700 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 298.0
If we subtract 696 from 700, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 87

On to step 6:
49 divided by 87 is 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 2980.0
Subtracting 0 from 49 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
87 goes into 490 5 times with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 2980.5
Deduct 435 from 490 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
87 can be fit into 550 6 times, resulting in a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 2980.56
If we take 522 away from 550, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
87 can be fit into 280 3 times, resulting in a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 2980.563
Subtracting 261 from 280 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
The number 87 fits into 190 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2980.5632
If we take 174 away from 190, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
87 can be fit into 160 1 times, resulting in a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 2980.56321
If we take 87 away from 160, 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.

Let's proceed to step 12:
730 divided by 87 is 8 with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 2980.563218
Subtract 696 from 730 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
87 can be fit into 340 3 times, resulting in a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 2980.5632183
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 14:
87 goes into 790 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 2980.56321839
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.

The final outcome is 2980.56321839, with a leftover of 7e-09.
