612115 divided by 87 
The aim is to understand the frequency of 87 in 612115.

Going ahead to step 1:
87 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 87

Advancing to step 2:
87 can be fit into 61 0 times, resulting in a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Grab the next digit (2) from the dividend, add it to 61, then carry on: 612 / 87

Advancing to step 3:
If we divide 612 by 87, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 3 after subtracting 609 from 612.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 87

Moving on to step 4:
31 divided by 87 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 87

On to step 5:
87 can be fit into 311 3 times, resulting in a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 703.0
Subtracting 261 from 311 leaves us with 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 87

Let's proceed to step 6:
When dividing 505 by 87, we get 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 7035.0
If we subtract 435 from 505, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 7:
700 divided by 87 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 7035.8
Deduct 696 from 700 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 87, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7035.8
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
If we divide 400 by 87, we get 4 and a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 7035.804
Deduct 348 from 400 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
87 can be fit into 520 5 times, resulting in a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 7035.8045
Deduct 435 from 520 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 11:
The number 87 fits into 850 9 times, leaving a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 7035.80459
Subtracting 783 from 850 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 12:
670 divided by 87 is 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 7035.804597
If we subtract 609 from 670, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 13:
The number 87 fits into 610 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7035.8045977
Deduct 609 from 610 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 7035.8045977, with a leftover of 1e-08.
