36572500 ÷ 87 
The aim is to understand the frequency of 87 in 36572500.

Step 1:
If we divide 3 by 87, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 87

Let's proceed to step 2:
87 can be fit into 36 0 times, resulting in a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Bring next digit (5) of the dividend behind the 36 and repeat the process: 365 / 87

Step 3:
365 divided by 87 is 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 17 after subtracting 348 from 365.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 87

Advancing to step 4:
87 can be fit into 177 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 42.0
If we subtract 174 from 177, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 87

Advancing to step 5:
When dividing 32 by 87, we get 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 420.0
The remainder is 32 after subtracting 0 from 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 87

Advancing to step 6:
325 divided by 87 is 3 with a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 4203.0
If we take 261 away from 325, we end up with 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 87

Going ahead to step 7:
When dividing 640 by 87, we get 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 42037.0
If we take 609 away from 640, we end up with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 87

Let's proceed to step 8:
87 goes into 310 3 times with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 420373.0
Deduct 261 from 310 and we're left 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.

Let's proceed to step 9:
490 divided by 87 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 420373.5
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.

On to step 10:
When dividing 550 by 87, we get 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 420373.56
Deduct 522 from 550 and we're left 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.

Let's proceed to step 11:
87 can be fit into 280 3 times, resulting in a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 420373.563
If we take 261 away from 280, we end up 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.

On to step 12:
87 can be fit into 190 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 420373.5632
The remainder is 16 after subtracting 174 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
If we divide 160 by 87, we get 1 and a remainder of 73.
The next digit of our result is 1. 
Result so far: 420373.56321
If we subtract 87 from 160, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 14:
87 can be fit into 730 8 times, resulting in a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 420373.563218
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.

Going ahead to step 15:
87 goes into 340 3 times with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 420373.5632183
The remainder is 79 after subtracting 261 from 340.
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 16:
The number 87 fits into 790 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 420373.56321839
Subtracting 783 from 790 leaves us with 7.
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 result is 420373.56321839 with a remainder of 7e-09.
