We look at the division of 82400369 by 878 
We want to figure out the number of times 82400369 can be divided by 878.

Let's proceed to step 1:
When dividing 8 by 878, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 878

Advancing to step 2:
If we divide 82 by 878, we get 0 and a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Fetch the next digit (4) from the dividend, attach it to 82 and continue: 824 / 878

Advancing to step 3:
If we divide 824 by 878, we get 0 and a remainder of 824.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 824 to get 824.
Grab the next digit (0) from the dividend, add it to 824, then carry on: 8240 / 878

On to step 4:
8240 divided by 878 is 9 with a remainder of 338.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 7902 from 8240, we get 338.
Take the next digit (0) from the dividend and append it to 338, then repeat: 3380 / 878

Moving on to step 5:
878 can be fit into 3380 3 times, resulting in a remainder of 746.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
If we subtract 2634 from 3380, we get 746.
Take the next digit (3) from the dividend and append it to 746, then repeat: 7463 / 878

On to step 6:
If we divide 7463 by 878, we get 8 and a remainder of 439.
Record the quotient 8 as the next digit in the result. 
Result so far: 938.0
The remainder is 439 after subtracting 7024 from 7463.
Take the next digit (6) from the dividend and append it to 439, then repeat: 4396 / 878

Step 7:
If we divide 4396 by 878, we get 5 and a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 9385.0
Subtract 4390 from 4396 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 878

Moving on to step 8:
The number 878 fits into 69 0 times, leaving a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 93850.0
Subtracting 0 from 69 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 9:
When dividing 690 by 878, we get 0 with a remainder of 690.
The number 0 becomes the next digit in our result. 
Result so far: 93850.0
If we take 0 away from 690, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 10:
6900 divided by 878 is 7 with a remainder of 754.
Write down 7 as next digit of the result. 
Result so far: 93850.07
Deduct 6146 from 6900 and we're left with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Moving on to step 11:
The number 878 fits into 7540 8 times, leaving a remainder of 516.
Use 8 as the next digit of our solution. 
Result so far: 93850.078
If we subtract 7024 from 7540, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 12:
The number 878 fits into 5160 5 times, leaving a remainder of 770.
Use 5 as the next digit of our solution. 
Result so far: 93850.0785
Deduct 4390 from 5160 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Let's proceed to step 13:
878 can be fit into 7700 8 times, resulting in a remainder of 676.
Record the quotient 8 as the next digit in the result. 
Result so far: 93850.07858
If we take 7024 away from 7700, we end up with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Advancing to step 14:
The number 878 fits into 6760 7 times, leaving a remainder of 614.
The number 7 becomes the next digit in our result. 
Result so far: 93850.078587
If we take 6146 away from 6760, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Let's proceed to step 15:
878 can be fit into 6140 6 times, resulting in a remainder of 872.
Use 6 as the next digit of our solution. 
Result so far: 93850.0785876
Subtracting 5268 from 6140 leaves us with 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

On to step 16:
If we divide 8720 by 878, we get 9 and a remainder of 818.
The next digit of our result is 9. 
Result so far: 93850.07858769
The remainder is 818 after subtracting 7902 from 8720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

The quotient of the division is 93850.07858769, and the remainder is 8.18e-07.
