619248 ÷ 87 
The aim is to understand the frequency of 87 in 619248.

Going ahead to step 1:
If we divide 6 by 87, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 87

On to step 2:
61 divided by 87 is 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 87

Moving on to step 3:
If we divide 619 by 87, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 609 from 619 to get 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 87

Advancing to step 4:
The number 87 fits into 102 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we take 87 away from 102, we end up with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 87

Going ahead to step 5:
154 divided by 87 is 1 with a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 711.0
Subtracting 87 from 154 leaves us with 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 87

Step 6:
If we divide 678 by 87, we get 7 and a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 7117.0
If we take 609 away from 678, we end up 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.

Step 7:
690 divided by 87 is 7 with a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 7117.7
Deduct 609 from 690 and we're left 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.

On to step 8:
The number 87 fits into 810 9 times, leaving a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 7117.79
Subtract 783 from 810 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
87 goes into 270 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 7117.793
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.

On to step 10:
The number 87 fits into 90 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 7117.7931
The remainder is 3 after subtracting 87 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
The number 87 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7117.7931
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
If we divide 300 by 87, we get 3 and a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 7117.793103
The remainder is 39 after subtracting 261 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
87 goes into 390 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 7117.7931034
The remainder is 42 after subtracting 348 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
If we divide 420 by 87, we get 4 and a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 7117.79310344
If we subtract 348 from 420, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 7117.79310344 with a remainder of 7.2e-08.
