We look at the division of 79408978 by 854 
We want to divide 79408978 by 854.

Let's proceed to step 1:
If we divide 7 by 854, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 854

Advancing to step 2:
854 can be fit into 79 0 times, resulting in a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Include the next digit (4) from the dividend after 79, then repeat: 794 / 854

Going ahead to step 3:
If we divide 794 by 854, we get 0 and a remainder of 794.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 794 and we're left with 794.
Grab the next digit (0) from the dividend, add it to 794, then carry on: 7940 / 854

Let's proceed to step 4:
The number 854 fits into 7940 9 times, leaving a remainder of 254.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7686 away from 7940, we end up with 254.
Bring next digit (8) of the dividend behind the 254 and repeat the process: 2548 / 854

Going ahead to step 5:
854 goes into 2548 2 times with a remainder of 840.
The next digit of our result is 2. 
Result so far: 92.0
The remainder is 840 after subtracting 1708 from 2548.
Include the next digit (9) from the dividend after 840, then repeat: 8409 / 854

Step 6:
8409 divided by 854 is 9 with a remainder of 723.
Record the quotient 9 as the next digit in the result. 
Result so far: 929.0
If we take 7686 away from 8409, we end up with 723.
Include the next digit (7) from the dividend after 723, then repeat: 7237 / 854

Advancing to step 7:
854 can be fit into 7237 8 times, resulting in a remainder of 405.
Write down 8 as next digit of the result. 
Result so far: 9298.0
If we take 6832 away from 7237, we end up with 405.
Bring next digit (8) of the dividend behind the 405 and repeat the process: 4058 / 854

Step 8:
If we divide 4058 by 854, we get 4 and a remainder of 642.
Put 4 as the next digit of the answer. 
Result so far: 92984.0
Subtract 3416 from 4058 to get 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Moving on to step 9:
If we divide 6420 by 854, we get 7 and a remainder of 442.
Put 7 as the next digit of the answer. 
Result so far: 92984.7
Subtracting 5978 from 6420 leaves us with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Going ahead to step 10:
854 goes into 4420 5 times with a remainder of 150.
The next digit of our result is 5. 
Result so far: 92984.75
Subtract 4270 from 4420 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
When dividing 1500 by 854, we get 1 with a remainder of 646.
Write down 1 as next digit of the result. 
Result so far: 92984.751
If we take 854 away from 1500, we end up with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

On to step 12:
6460 divided by 854 is 7 with a remainder of 482.
The next digit of our result is 7. 
Result so far: 92984.7517
Subtracting 5978 from 6460 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 13:
The number 854 fits into 4820 5 times, leaving a remainder of 550.
The number 5 becomes the next digit in our result. 
Result so far: 92984.75175
If we subtract 4270 from 4820, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 14:
The number 854 fits into 5500 6 times, leaving a remainder of 376.
The next digit of our result is 6. 
Result so far: 92984.751756
Deduct 5124 from 5500 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 15:
When dividing 3760 by 854, we get 4 with a remainder of 344.
The number 4 becomes the next digit in our result. 
Result so far: 92984.7517564
If we subtract 3416 from 3760, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 16:
854 can be fit into 3440 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 92984.75175644
If we take 3416 away from 3440, we end up 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.

The final result is 92984.75175644 with a remainder of 2.4e-08.
