We look at the division of 597547 by 87 
The aim is to understand the frequency of 87 in 597547.

Advancing to step 1:
If we divide 5 by 87, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 87

Step 2:
If we divide 59 by 87, we get 0 and a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Take the next digit (7) from the dividend and append it to 59, then repeat: 597 / 87

Going ahead to step 3:
If we divide 597 by 87, we get 6 and a remainder of 75.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 522 away from 597, we end up with 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 87

Let's proceed to step 4:
87 can be fit into 755 8 times, resulting in a remainder of 59.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
The remainder is 59 after subtracting 696 from 755.
Take the next digit (4) from the dividend and append it to 59, then repeat: 594 / 87

Step 5:
87 goes into 594 6 times with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 686.0
Subtract 522 from 594 to get 72.
Append the next digit (7) from the dividend to 72 and continue with: 727 / 87

Going ahead to step 6:
If we divide 727 by 87, we get 8 and a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 6868.0
Subtract 696 from 727 to 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.

Going ahead to step 7:
If we divide 310 by 87, we get 3 and a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 6868.3
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 8:
87 goes into 490 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 6868.35
The remainder is 55 after subtracting 435 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
87 can be fit into 550 6 times, resulting in a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 6868.356
Subtract 522 from 550 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
When dividing 280 by 87, we get 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 6868.3563
The remainder is 19 after subtracting 261 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
87 goes into 190 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 6868.35632
If we take 174 away from 190, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
The number 87 fits into 160 1 times, leaving a remainder of 73.
The next digit of our result is 1. 
Result so far: 6868.356321
If we take 87 away from 160, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 13:
The number 87 fits into 730 8 times, leaving a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 6868.3563218
Deduct 696 from 730 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
The number 87 fits into 340 3 times, leaving a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 6868.35632183
Subtract 261 from 340 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

In conclusion, the division gives 6868.35632183 with a balance of 7.9e-08.
