We're dividing 87359051 by 802 
The aim is to understand the frequency of 802 in 87359051.

Step 1:
The number 802 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 802

Going ahead to step 2:
802 goes into 87 0 times with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Include the next digit (3) from the dividend after 87, then repeat: 873 / 802

Let's proceed to step 3:
873 divided by 802 is 1 with a remainder of 71.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 802 from 873, we get 71.
Fetch the next digit (5) from the dividend, attach it to 71 and continue: 715 / 802

Going ahead to step 4:
When dividing 715 by 802, we get 0 with a remainder of 715.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 715 to get 715.
Include the next digit (9) from the dividend after 715, then repeat: 7159 / 802

Let's proceed to step 5:
802 goes into 7159 8 times with a remainder of 743.
The next digit of our result is 8. 
Result so far: 108.0
Subtracting 6416 from 7159 leaves us with 743.
Include the next digit (0) from the dividend after 743, then repeat: 7430 / 802

Let's proceed to step 6:
If we divide 7430 by 802, we get 9 and a remainder of 212.
Put 9 as the next digit of the answer. 
Result so far: 1089.0
The remainder is 212 after subtracting 7218 from 7430.
Fetch the next digit (5) from the dividend, attach it to 212 and continue: 2125 / 802

Step 7:
When dividing 2125 by 802, we get 2 with a remainder of 521.
The next digit of our result is 2. 
Result so far: 10892.0
Subtract 1604 from 2125 to get 521.
Bring next digit (1) of the dividend behind the 521 and repeat the process: 5211 / 802

Let's proceed to step 8:
If we divide 5211 by 802, we get 6 and a remainder of 399.
The number 6 becomes the next digit in our result. 
Result so far: 108926.0
If we take 4812 away from 5211, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Step 9:
802 can be fit into 3990 4 times, resulting in a remainder of 782.
The next digit of our result is 4. 
Result so far: 108926.4
If we take 3208 away from 3990, we end up with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Moving on to step 10:
802 goes into 7820 9 times with a remainder of 602.
Record the quotient 9 as the next digit in the result. 
Result so far: 108926.49
The remainder is 602 after subtracting 7218 from 7820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Step 11:
The number 802 fits into 6020 7 times, leaving a remainder of 406.
The number 7 becomes the next digit in our result. 
Result so far: 108926.497
Deduct 5614 from 6020 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 12:
When dividing 4060 by 802, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 108926.4975
The remainder is 50 after subtracting 4010 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
500 divided by 802 is 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 108926.4975
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 14:
The number 802 fits into 5000 6 times, leaving a remainder of 188.
The next digit of our result is 6. 
Result so far: 108926.497506
Deduct 4812 from 5000 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 15:
1880 divided by 802 is 2 with a remainder of 276.
Use 2 as the next digit of our solution. 
Result so far: 108926.4975062
Deduct 1604 from 1880 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 16:
When dividing 2760 by 802, we get 3 with a remainder of 354.
The number 3 becomes the next digit in our result. 
Result so far: 108926.49750623
Deduct 2406 from 2760 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

After the division, we end up with 108926.49750623 and a remainder of 3.54e-07.
