863907 ÷ 84 
The aim is to understand the frequency of 84 in 863907.

Advancing to step 1:
84 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 84

Step 2:
84 can be fit into 86 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 84 from 86 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 84

Advancing to step 3:
If we divide 23 by 84, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 23, we end up with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 84

Step 4:
When dividing 239 by 84, we get 2 with a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtract 168 from 239 to get 71.
Grab the next digit (0) from the dividend, add it to 71, then carry on: 710 / 84

Step 5:
The number 84 fits into 710 8 times, leaving a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 1028.0
Subtract 672 from 710 to get 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 84

Moving on to step 6:
84 can be fit into 387 4 times, resulting in a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 10284.0
If we take 336 away from 387, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
510 divided by 84 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 10284.6
Subtracting 504 from 510 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 84, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10284.6
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
84 goes into 600 7 times with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 10284.607
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
The number 84 fits into 120 1 times, leaving a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 10284.6071
Subtract 84 from 120 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.

On to step 11:
When dividing 360 by 84, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 10284.60714
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
The number 84 fits into 240 2 times, leaving a remainder of 72.
The next digit of our result is 2. 
Result so far: 10284.607142
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 13:
The number 84 fits into 720 8 times, leaving a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 10284.6071428
Deduct 672 from 720 and we're left 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.

Step 14:
84 can be fit into 480 5 times, resulting in a remainder of 60.
The next digit of our result is 5. 
Result so far: 10284.60714285
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 10284.60714285 with a balance of 6e-08.
