Let's divide 691734 by 87
The aim is to understand the frequency of 87 in 691734.

Going ahead to step 1:
87 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 87

On to step 2:
69 divided by 87 is 0 with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 87

Let's proceed to step 3:
When dividing 691 by 87, we get 7 with a remainder of 82.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 609 from 691 and we're left with 82.
Append the next digit (7) from the dividend to 82 and continue with: 827 / 87

Let's proceed to step 4:
827 divided by 87 is 9 with a remainder of 44.
The next digit of our result is 9. 
Result so far: 79.0
Deduct 783 from 827 and we're left with 44.
Fetch the next digit (3) from the dividend, attach it to 44 and continue: 443 / 87

Going ahead to step 5:
443 divided by 87 is 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 795.0
Subtracting 435 from 443 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 87

Let's proceed to step 6:
The number 87 fits into 84 0 times, leaving a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 7950.0
Deduct 0 from 84 and we're left 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.

Let's proceed to step 7:
87 goes into 840 9 times with a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 7950.9
If we subtract 783 from 840, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 8:
87 goes into 570 6 times with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 7950.96
If we take 522 away from 570, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
The number 87 fits into 480 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 7950.965
If we subtract 435 from 480, we get 45.
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:
87 can be fit into 450 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7950.9655
Subtracting 435 from 450 leaves us with 15.
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 7950.9655, with a leftover of 0.00015.
