We divide 912383 by 87
The aim is to understand the frequency of 87 in 912383.

On to step 1:
When dividing 9 by 87, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 87

Moving on to step 2:
The number 87 fits into 91 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 87 from 91 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 87

On to step 3:
The number 87 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 42, we end up with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 87

On to step 4:
The number 87 fits into 423 4 times, leaving a remainder of 75.
Put 4 as the next digit of the answer. 
Result so far: 104.0
If we subtract 348 from 423, we get 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 87

On to step 5:
87 can be fit into 758 8 times, resulting in a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 1048.0
Deduct 696 from 758 and we're left with 62.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 87

Let's proceed to step 6:
87 can be fit into 623 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 10487.0
Deduct 609 from 623 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
When dividing 140 by 87, we get 1 with a remainder of 53.
The next digit of our result is 1. 
Result so far: 10487.1
If we take 87 away from 140, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 8:
If we divide 530 by 87, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 10487.16
If we take 522 away from 530, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
87 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 10487.16
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
If we divide 800 by 87, we get 9 and a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 10487.1609
The remainder is 17 after subtracting 783 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
87 goes into 170 1 times with a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 10487.16091
Subtracting 87 from 170 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 12:
The number 87 fits into 830 9 times, leaving a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 10487.160919
If we take 783 away from 830, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 13:
87 goes into 470 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 10487.1609195
If we subtract 435 from 470, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
The number 87 fits into 350 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 10487.16091954
The remainder is 2 after subtracting 348 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 10487.16091954 with a remaining 2e-09.
