We look at the division of 719052 by 87 
The aim is to understand the frequency of 87 in 719052.

Step 1:
If we divide 7 by 87, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 87

Advancing to step 2:
If we divide 71 by 87, we get 0 and a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Grab the next digit (9) from the dividend, add it to 71, then carry on: 719 / 87

Going ahead to step 3:
87 can be fit into 719 8 times, resulting in a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 696 from 719 and we're left with 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 87

Let's proceed to step 4:
230 divided by 87 is 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Subtract 174 from 230 to get 56.
Append the next digit (5) from the dividend to 56 and continue with: 565 / 87

Moving on to step 5:
When dividing 565 by 87, we get 6 with a remainder of 43.
The next digit of our result is 6. 
Result so far: 826.0
If we take 522 away from 565, we end up with 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 87

Going ahead to step 6:
87 goes into 432 4 times with a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 8264.0
Subtracting 348 from 432 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 7:
The number 87 fits into 840 9 times, leaving a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 8264.9
The remainder is 57 after subtracting 783 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 8:
87 can be fit into 570 6 times, resulting in a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 8264.96
If we subtract 522 from 570, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
480 divided by 87 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 8264.965
The remainder is 45 after subtracting 435 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
If we divide 450 by 87, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 8264.9655
The remainder is 15 after subtracting 435 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 8264.9655, with a leftover of 0.00015.
