We look at the division of 78813875 by 84 
We want to figure out the number of times 78813875 can be divided by 84.

On to step 1:
When dividing 7 by 84, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 84

Advancing to step 2:
84 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 84

Going ahead to step 3:
788 divided by 84 is 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 756 from 788, we get 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 84

Step 4:
84 can be fit into 321 3 times, resulting in a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Subtract 252 from 321 to get 69.
Fetch the next digit (3) from the dividend, attach it to 69 and continue: 693 / 84

Step 5:
84 can be fit into 693 8 times, resulting in a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 938.0
The remainder is 21 after subtracting 672 from 693.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 84

Moving on to step 6:
The number 84 fits into 218 2 times, leaving a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 9382.0
Subtracting 168 from 218 leaves us with 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 84

On to step 7:
The number 84 fits into 507 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 93826.0
If we take 504 away from 507, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 84

Advancing to step 8:
84 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 938260.0
Deduct 0 from 35 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
The number 84 fits into 350 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 938260.4
If we subtract 336 from 350, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
84 goes into 140 1 times with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 938260.41
Deduct 84 from 140 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
If we divide 560 by 84, we get 6 and a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 938260.416
Deduct 504 from 560 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
If we divide 560 by 84, we get 6 and a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 938260.4166
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 938260.4166 with a remaining 0.00056.
