926919 ÷ 87 
The aim is to understand the frequency of 87 in 926919.

Step 1:
When dividing 9 by 87, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 87

Moving on to step 2:
87 can be fit into 92 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 87 from 92 and we're left with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 87

Moving on to step 3:
56 divided by 87 is 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 56 leaves us with 56.
Grab the next digit (9) from the dividend, add it to 56, then carry on: 569 / 87

Let's proceed to step 4:
87 goes into 569 6 times with a remainder of 47.
The next digit of our result is 6. 
Result so far: 106.0
Subtract 522 from 569 to get 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 87

Moving on to step 5:
87 goes into 471 5 times with a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 1065.0
The remainder is 36 after subtracting 435 from 471.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 87

Step 6:
When dividing 369 by 87, we get 4 with a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 10654.0
If we subtract 348 from 369, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
The number 87 fits into 210 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 10654.2
The remainder is 36 after subtracting 174 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
87 goes into 360 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 10654.24
If we take 348 away from 360, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
When dividing 120 by 87, we get 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 10654.241
Subtract 87 from 120 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 10:
The number 87 fits into 330 3 times, leaving a remainder of 69.
The next digit of our result is 3. 
Result so far: 10654.2413
Deduct 261 from 330 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 11:
690 divided by 87 is 7 with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 10654.24137
Subtracting 609 from 690 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 12:
87 goes into 810 9 times with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 10654.241379
Deduct 783 from 810 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
270 divided by 87 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 10654.2413793
Deduct 261 from 270 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
90 divided by 87 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 10654.24137931
Subtract 87 from 90 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 10654.24137931 with a remaining 3e-09.
