We divide 11999887 by 84
We want to figure out the number of times 11999887 can be divided by 84.

Step 1:
1 divided by 84 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 84

Let's proceed to step 2:
84 can be fit into 11 0 times, resulting in a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 84

Moving on to step 3:
119 divided by 84 is 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 84 from 119, we get 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 84

Let's proceed to step 4:
When dividing 359 by 84, we get 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 336 away from 359, we end up with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 84

On to step 5:
84 can be fit into 239 2 times, resulting in a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtract 168 from 239 to get 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 84

Advancing to step 6:
718 divided by 84 is 8 with a remainder of 46.
The next digit of our result is 8. 
Result so far: 1428.0
Subtracting 672 from 718 leaves us with 46.
Include the next digit (8) from the dividend after 46, then repeat: 468 / 84

Moving on to step 7:
The number 84 fits into 468 5 times, leaving a remainder of 48.
Put 5 as the next digit of the answer. 
Result so far: 14285.0
Deduct 420 from 468 and we're left with 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 84

Advancing to step 8:
The number 84 fits into 487 5 times, leaving a remainder of 67.
Record the quotient 5 as the next digit in the result. 
Result so far: 142855.0
Subtracting 420 from 487 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
670 divided by 84 is 7 with a remainder of 82.
Record the quotient 7 as the next digit in the result. 
Result so far: 142855.7
Subtracting 588 from 670 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 10:
820 divided by 84 is 9 with a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 142855.79
The remainder is 64 after subtracting 756 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
If we divide 640 by 84, we get 7 and a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 142855.797
If we subtract 588 from 640, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
When dividing 520 by 84, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 142855.7976
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
84 can be fit into 160 1 times, resulting in a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 142855.79761
Subtract 84 from 160 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
If we divide 760 by 84, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 142855.797619
Subtracting 756 from 760 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 15:
84 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 142855.797619
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 16:
If we divide 400 by 84, we get 4 and a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 142855.79761904
The remainder is 64 after subtracting 336 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 142855.79761904 with a remainder of 6.4e-08.
