28172703 divided by 84 
We want to figure out the number of times 28172703 can be divided by 84.

Let's proceed to step 1:
When dividing 2 by 84, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 84

Moving on to step 2:
When dividing 28 by 84, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 84

Advancing to step 3:
The number 84 fits into 281 3 times, leaving a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 252 from 281, we get 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 84

Advancing to step 4:
297 divided by 84 is 3 with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 252 away from 297, we end up with 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 84

Step 5:
84 goes into 452 5 times with a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 335.0
Deduct 420 from 452 and we're left with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 84

Going ahead to step 6:
84 can be fit into 327 3 times, resulting in a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 3353.0
Deduct 252 from 327 and we're left with 75.
Fetch the next digit (0) from the dividend, attach it to 75 and continue: 750 / 84

Advancing to step 7:
When dividing 750 by 84, we get 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 33538.0
If we take 672 away from 750, we end up with 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 84

Moving on to step 8:
If we divide 783 by 84, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 335389.0
The remainder is 27 after subtracting 756 from 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
270 divided by 84 is 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 335389.3
Deduct 252 from 270 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
The number 84 fits into 180 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 335389.32
The remainder is 12 after subtracting 168 from 180.
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 11:
84 can be fit into 120 1 times, resulting in a remainder of 36.
The next digit of our result is 1. 
Result so far: 335389.321
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.

Let's proceed to step 12:
The number 84 fits into 360 4 times, leaving a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 335389.3214
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 13:
240 divided by 84 is 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 335389.32142
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.

Step 14:
The number 84 fits into 720 8 times, leaving a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 335389.321428
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.

Advancing to step 15:
480 divided by 84 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 335389.3214285
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.

Going ahead to step 16:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 335389.32142857
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.

The final result is 335389.32142857 with a remainder of 1.2e-08.
