912108 ÷ 84 
We want to figure out the number of times 912108 can be divided by 84.

Going ahead to step 1:
The number 84 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 84

Going ahead to step 2:
When dividing 91 by 84, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 84 from 91 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 84

Step 3:
The number 84 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 72 after subtracting 0 from 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 84

Step 4:
84 can be fit into 721 8 times, resulting in a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Deduct 672 from 721 and we're left with 49.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 84

Going ahead to step 5:
If we divide 490 by 84, we get 5 and a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 1085.0
Subtracting 420 from 490 leaves us with 70.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 84

Step 6:
708 divided by 84 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 10858.0
The remainder is 36 after subtracting 672 from 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
If we divide 360 by 84, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 10858.4
Subtracting 336 from 360 leaves us 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 8:
The number 84 fits into 240 2 times, leaving a remainder of 72.
The next digit of our result is 2. 
Result so far: 10858.42
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 9:
84 can be fit into 720 8 times, resulting in a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 10858.428
If we subtract 672 from 720, we get 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 10:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 10858.4285
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.

Let's proceed to step 11:
600 divided by 84 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 10858.42857
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.

Moving on to step 12:
84 goes into 120 1 times with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 10858.428571
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
If we divide 360 by 84, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 10858.4285714
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.

Advancing to step 14:
84 goes into 240 2 times with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 10858.42857142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 10858.42857142, with a leftover of 7.2e-08.
