516568 ÷ 87 
The aim is to understand the frequency of 87 in 516568.

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
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 87

Going ahead to step 2:
87 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 87

Advancing to step 3:
516 divided by 87 is 5 with a remainder of 81.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 435 from 516 to get 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 87

Step 4:
The number 87 fits into 815 9 times, leaving a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 59.0
Deduct 783 from 815 and we're left with 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 87

On to step 5:
The number 87 fits into 326 3 times, leaving a remainder of 65.
The next digit of our result is 3. 
Result so far: 593.0
Subtract 261 from 326 to get 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 87

Let's proceed to step 6:
If we divide 658 by 87, we get 7 and a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 5937.0
If we subtract 609 from 658, 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.

Moving on to step 7:
490 divided by 87 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 5937.5
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.

Let's proceed to step 8:
If we divide 550 by 87, we get 6 and a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 5937.56
Deduct 522 from 550 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
The number 87 fits into 280 3 times, leaving a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 5937.563
If we subtract 261 from 280, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
87 can be fit into 190 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 5937.5632
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.

Advancing to step 11:
When dividing 160 by 87, we get 1 with a remainder of 73.
The next digit of our result is 1. 
Result so far: 5937.56321
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.

Let's proceed to step 12:
87 can be fit into 730 8 times, resulting in a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 5937.563218
The remainder is 34 after subtracting 696 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
When dividing 340 by 87, we get 3 with a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 5937.5632183
If we subtract 261 from 340, we 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.

Going ahead to step 14:
The number 87 fits into 790 9 times, leaving a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 5937.56321839
If we take 783 away from 790, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 5937.56321839 with a balance of 7e-09.
