We look at the division of 974024 by 87 
The aim is to understand the frequency of 87 in 974024.

Moving on to step 1:
If we divide 9 by 87, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 87

Let's proceed to step 2:
87 goes into 97 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 10 after subtracting 87 from 97.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 87

Going ahead to step 3:
87 can be fit into 104 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 17 after subtracting 87 from 104.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 87

On to step 4:
87 can be fit into 170 1 times, resulting in a remainder of 83.
The next digit of our result is 1. 
Result so far: 111.0
Subtract 87 from 170 to get 83.
Include the next digit (2) from the dividend after 83, then repeat: 832 / 87

Let's proceed to step 5:
832 divided by 87 is 9 with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 1119.0
If we subtract 783 from 832, we get 49.
Fetch the next digit (4) from the dividend, attach it to 49 and continue: 494 / 87

Going ahead to step 6:
When dividing 494 by 87, we get 5 with a remainder of 59.
Put 5 as the next digit of the answer. 
Result so far: 11195.0
The remainder is 59 after subtracting 435 from 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
87 can be fit into 590 6 times, resulting in a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 11195.6
Subtract 522 from 590 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
87 can be fit into 680 7 times, resulting in a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 11195.67
Subtract 609 from 680 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 9:
When dividing 710 by 87, we get 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 11195.678
Deduct 696 from 710 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
140 divided by 87 is 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 11195.6781
Deduct 87 from 140 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
If we divide 530 by 87, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 11195.67816
The remainder is 8 after subtracting 522 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
80 divided by 87 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 11195.67816
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
The number 87 fits into 800 9 times, leaving a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 11195.6781609
The remainder is 17 after subtracting 783 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
When dividing 170 by 87, we get 1 with a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 11195.67816091
Subtract 87 from 170 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The quotient of the division is 11195.67816091, and the remainder is 8.3e-08.
