We divide 394669 by 87
The aim is to understand the frequency of 87 in 394669.

On to step 1:
87 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 87

Step 2:
87 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 87

Let's proceed to step 3:
87 goes into 394 4 times with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 348 from 394 and we're left with 46.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 87

Step 4:
The number 87 fits into 466 5 times, leaving a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
The remainder is 31 after subtracting 435 from 466.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 87

On to step 5:
When dividing 316 by 87, we get 3 with a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 453.0
The remainder is 55 after subtracting 261 from 316.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 87

Step 6:
559 divided by 87 is 6 with a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 4536.0
If we subtract 522 from 559, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
87 can be fit into 370 4 times, resulting in a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 4536.4
The remainder is 22 after subtracting 348 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
If we divide 220 by 87, we get 2 and a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 4536.42
Subtracting 174 from 220 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
87 can be fit into 460 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4536.425
Subtract 435 from 460 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
250 divided by 87 is 2 with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 4536.4252
The remainder is 76 after subtracting 174 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 11:
87 can be fit into 760 8 times, resulting in a remainder of 64.
The next digit of our result is 8. 
Result so far: 4536.42528
Subtract 696 from 760 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
87 goes into 640 7 times with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 4536.425287
If we subtract 609 from 640, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
If we divide 310 by 87, we get 3 and a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 4536.4252873
The remainder is 49 after subtracting 261 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 14:
87 goes into 490 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 4536.42528735
Deduct 435 from 490 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 4536.42528735 and a remainder of 5.5e-08.
