62394 ÷ 87 
The aim is to understand the frequency of 87 in 62394.

On to step 1:
If we divide 6 by 87, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 87

Moving on to step 2:
62 divided by 87 is 0 with a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 87

Advancing to step 3:
623 divided by 87 is 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 14 after subtracting 609 from 623.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 87

Step 4:
149 divided by 87 is 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Deduct 87 from 149 and we're left with 62.
Fetch the next digit (4) from the dividend, attach it to 62 and continue: 624 / 87

On to step 5:
87 can be fit into 624 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 717.0
The remainder is 15 after subtracting 609 from 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 6:
87 can be fit into 150 1 times, resulting in a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 717.1
If we subtract 87 from 150, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
If we divide 630 by 87, we get 7 and a remainder of 21.
The next digit of our result is 7. 
Result so far: 717.17
If we subtract 609 from 630, 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.

Let's proceed to step 8:
210 divided by 87 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 717.172
Subtract 174 from 210 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
The number 87 fits into 360 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 717.1724
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.

Going ahead to step 10:
87 goes into 120 1 times with a remainder of 33.
The next digit of our result is 1. 
Result so far: 717.17241
If we subtract 87 from 120, we 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.

Let's proceed to step 11:
When dividing 330 by 87, we get 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 717.172413
Subtract 261 from 330 to get 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 12:
The number 87 fits into 690 7 times, leaving a remainder of 81.
The next digit of our result is 7. 
Result so far: 717.1724137
If we subtract 609 from 690, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 13:
When dividing 810 by 87, we get 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 717.17241379
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.

The final result is 717.17241379 with a remainder of 2.7e-08.
