Let's divide 189527 by 87
The aim is to understand the frequency of 87 in 189527.

On to step 1:
The number 87 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 87

Moving on to step 2:
The number 87 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 87

On to step 3:
87 goes into 189 2 times with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 15 after subtracting 174 from 189.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 87

Moving on to step 4:
The number 87 fits into 155 1 times, leaving a remainder of 68.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 87 from 155, we get 68.
Fetch the next digit (2) from the dividend, attach it to 68 and continue: 682 / 87

Step 5:
If we divide 682 by 87, we get 7 and a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 217.0
The remainder is 73 after subtracting 609 from 682.
Fetch the next digit (7) from the dividend, attach it to 73 and continue: 737 / 87

Step 6:
If we divide 737 by 87, we get 8 and a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 2178.0
If we take 696 away from 737, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
87 can be fit into 410 4 times, resulting in a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 2178.4
Deduct 348 from 410 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
The number 87 fits into 620 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 2178.47
Subtracting 609 from 620 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
The number 87 fits into 110 1 times, leaving a remainder of 23.
The next digit of our result is 1. 
Result so far: 2178.471
If we subtract 87 from 110, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
If we divide 230 by 87, we get 2 and a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 2178.4712
If we take 174 away from 230, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
The number 87 fits into 560 6 times, leaving a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 2178.47126
Subtracting 522 from 560 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
When dividing 380 by 87, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 2178.471264
Subtract 348 from 380 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
The number 87 fits into 320 3 times, leaving a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 2178.4712643
Subtracting 261 from 320 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 14:
87 can be fit into 590 6 times, resulting in a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 2178.47126436
The remainder is 68 after subtracting 522 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 2178.47126436, with a leftover of 6.8e-08.
