930345 divided by 87 
The aim is to understand the frequency of 87 in 930345.

Step 1:
When dividing 9 by 87, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 87

Step 2:
When dividing 93 by 87, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 87 from 93 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 87

Going ahead to step 3:
When dividing 60 by 87, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 60, we get 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 87

Advancing to step 4:
If we divide 603 by 87, we get 6 and a remainder of 81.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
Subtract 522 from 603 to get 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 87

Step 5:
87 can be fit into 814 9 times, resulting in a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 1069.0
If we subtract 783 from 814, we get 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 87

Step 6:
When dividing 315 by 87, we get 3 with a remainder of 54.
The next digit of our result is 3. 
Result so far: 10693.0
Subtracting 261 from 315 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
87 can be fit into 540 6 times, resulting in a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 10693.6
Deduct 522 from 540 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
180 divided by 87 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 10693.62
Subtract 174 from 180 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
87 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 10693.62
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
600 divided by 87 is 6 with a remainder of 78.
Record the quotient 6 as the next digit in the result. 
Result so far: 10693.6206
Deduct 522 from 600 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
87 goes into 780 8 times with a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 10693.62068
Subtract 696 from 780 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
87 can be fit into 840 9 times, resulting in a remainder of 57.
The next digit of our result is 9. 
Result so far: 10693.620689
Subtracting 783 from 840 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 13:
570 divided by 87 is 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 10693.6206896
If we subtract 522 from 570, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
87 can be fit into 480 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 10693.62068965
Deduct 435 from 480 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The quotient of the division is 10693.62068965, and the remainder is 4.5e-08.
