108921 divided by 84 
We want to figure out the number of times 108921 can be divided by 84.

On to step 1:
The number 84 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 84

Going ahead to step 2:
If we divide 10 by 84, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 84

Step 3:
84 goes into 108 1 times with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 84 away from 108, we end up with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 84

Moving on to step 4:
If we divide 249 by 84, we get 2 and a remainder of 81.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 168 from 249 leaves us with 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 84

Let's proceed to step 5:
The number 84 fits into 812 9 times, leaving a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
If we subtract 756 from 812, we get 56.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 84

Moving on to step 6:
The number 84 fits into 561 6 times, leaving a remainder of 57.
Write down 6 as next digit of the result. 
Result so far: 1296.0
Subtracting 504 from 561 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
When dividing 570 by 84, we get 6 with a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 1296.6
Subtracting 504 from 570 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 8:
84 goes into 660 7 times with a remainder of 72.
The next digit of our result is 7. 
Result so far: 1296.67
If we subtract 588 from 660, 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.

Moving on to step 9:
84 goes into 720 8 times with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 1296.678
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 10:
84 goes into 480 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 1296.6785
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.

Advancing to step 11:
84 goes into 600 7 times with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 1296.67857
If we subtract 588 from 600, we 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.

Going ahead to step 12:
When dividing 120 by 84, we get 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1296.678571
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.

Going ahead to step 13:
The number 84 fits into 360 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 1296.6785714
Deduct 336 from 360 and we're left 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.

Let's proceed to step 14:
When dividing 240 by 84, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 1296.67857142
Subtract 168 from 240 to 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.

The final result is 1296.67857142 with a remainder of 7.2e-08.
