We're dividing 869523 by 84 
We want to figure out the number of times 869523 can be divided by 84.

Step 1:
8 divided by 84 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 84

Advancing to step 2:
84 goes into 86 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 84 from 86, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 84

Step 3:
29 divided by 84 is 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 29 and we're left with 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 84

Moving on to step 4:
84 can be fit into 295 3 times, resulting in a remainder of 43.
The next digit of our result is 3. 
Result so far: 103.0
If we take 252 away from 295, we end up with 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 84

Moving on to step 5:
432 divided by 84 is 5 with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 1035.0
Subtracting 420 from 432 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 84

Going ahead to step 6:
84 can be fit into 123 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 10351.0
Deduct 84 from 123 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
390 divided by 84 is 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 10351.4
Subtracting 336 from 390 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.

Advancing to step 8:
540 divided by 84 is 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 10351.46
Subtract 504 from 540 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 10351.464
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
84 goes into 240 2 times with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 10351.4642
Deduct 168 from 240 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
720 divided by 84 is 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 10351.46428
If we take 672 away from 720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 10351.464285
Deduct 420 from 480 and we're left 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.

On to step 13:
84 can be fit into 600 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 10351.4642857
Subtract 588 from 600 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 10351.46428571
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 10351.46428571 with a remaining 3.6e-08.
