We divide 839258 by 87
The aim is to understand the frequency of 87 in 839258.

Advancing to step 1:
8 divided by 87 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 87

On to step 2:
The number 87 fits into 83 0 times, leaving a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 87

Step 3:
87 goes into 839 9 times with a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 783 from 839 leaves us with 56.
Grab the next digit (2) from the dividend, add it to 56, then carry on: 562 / 87

Advancing to step 4:
87 can be fit into 562 6 times, resulting in a remainder of 40.
The next digit of our result is 6. 
Result so far: 96.0
Subtracting 522 from 562 leaves us with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 87

On to step 5:
If we divide 405 by 87, we get 4 and a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 964.0
If we subtract 348 from 405, we get 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 87

Let's proceed to step 6:
If we divide 578 by 87, we get 6 and a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 9646.0
If we subtract 522 from 578, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
When dividing 560 by 87, we get 6 with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 9646.6
Deduct 522 from 560 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
87 can be fit into 380 4 times, resulting in a remainder of 32.
The next digit of our result is 4. 
Result so far: 9646.64
If we take 348 away from 380, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
320 divided by 87 is 3 with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 9646.643
The remainder is 59 after subtracting 261 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
87 can be fit into 590 6 times, resulting in a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 9646.6436
Subtracting 522 from 590 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
If we divide 680 by 87, we get 7 and a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 9646.64367
If we subtract 609 from 680, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 12:
87 goes into 710 8 times with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 9646.643678
If we subtract 696 from 710, we get 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 13:
87 goes into 140 1 times with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 9646.6436781
The remainder is 53 after subtracting 87 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 14:
87 goes into 530 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 9646.64367816
The remainder is 8 after subtracting 522 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 9646.64367816 with a remaining 8e-09.
