225343 divided by 87 
The aim is to understand the frequency of 87 in 225343.

Step 1:
87 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 87

Moving on to step 2:
22 divided by 87 is 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 87

Advancing to step 3:
If we divide 225 by 87, we get 2 and a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 174 from 225 to get 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 87

Let's proceed to step 4:
87 can be fit into 513 5 times, resulting in a remainder of 78.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 435 from 513, we get 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 87

Step 5:
784 divided by 87 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 259.0
Subtracting 783 from 784 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 87

Moving on to step 6:
When dividing 13 by 87, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 2590.0
Subtracting 0 from 13 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
130 divided by 87 is 1 with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 2590.1
Deduct 87 from 130 and we're left 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.

Going ahead to step 8:
If we divide 430 by 87, we get 4 and a remainder of 82.
Write down 4 as next digit of the result. 
Result so far: 2590.14
Subtracting 348 from 430 leaves us 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.

Let's proceed to step 9:
87 goes into 820 9 times with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 2590.149
If we take 783 away from 820, we end up with 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 10:
370 divided by 87 is 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 2590.1494
Deduct 348 from 370 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
When dividing 220 by 87, we get 2 with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 2590.14942
Subtracting 174 from 220 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
460 divided by 87 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 2590.149425
Deduct 435 from 460 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 13:
250 divided by 87 is 2 with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 2590.1494252
If we subtract 174 from 250, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
When dividing 760 by 87, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 2590.14942528
Deduct 696 from 760 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 2590.14942528, and the remainder is 6.4e-08.
