We look at the division of 78919323 by 400 
Let's see how many times 400 fits into 78919323.

Let's proceed to step 1:
When dividing 7 by 400, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 400

On to step 2:
If we divide 78 by 400, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 400

Let's proceed to step 3:
The number 400 fits into 789 1 times, leaving a remainder of 389.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 400 from 789 and we're left with 389.
Include the next digit (1) from the dividend after 389, then repeat: 3891 / 400

Step 4:
If we divide 3891 by 400, we get 9 and a remainder of 291.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 3600 from 3891 and we're left with 291.
Append the next digit (9) from the dividend to 291 and continue with: 2919 / 400

Let's proceed to step 5:
If we divide 2919 by 400, we get 7 and a remainder of 119.
The next digit of our result is 7. 
Result so far: 197.0
Subtracting 2800 from 2919 leaves us with 119.
Grab the next digit (3) from the dividend, add it to 119, then carry on: 1193 / 400

Let's proceed to step 6:
The number 400 fits into 1193 2 times, leaving a remainder of 393.
Put 2 as the next digit of the answer. 
Result so far: 1972.0
The remainder is 393 after subtracting 800 from 1193.
Grab the next digit (2) from the dividend, add it to 393, then carry on: 3932 / 400

Advancing to step 7:
400 can be fit into 3932 9 times, resulting in a remainder of 332.
Put 9 as the next digit of the answer. 
Result so far: 19729.0
The remainder is 332 after subtracting 3600 from 3932.
Take the next digit (3) from the dividend and append it to 332, then repeat: 3323 / 400

Moving on to step 8:
400 can be fit into 3323 8 times, resulting in a remainder of 123.
The number 8 becomes the next digit in our result. 
Result so far: 197298.0
If we subtract 3200 from 3323, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
If we divide 1230 by 400, we get 3 and a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 197298.3
The remainder is 30 after subtracting 1200 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
400 can be fit into 300 0 times, resulting in a remainder of 300.
The next digit of our result is 0. 
Result so far: 197298.3
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
If we divide 3000 by 400, we get 7 and a remainder of 200.
Write down 7 as next digit of the result. 
Result so far: 197298.307
The remainder is 200 after subtracting 2800 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
The number 400 fits into 2000 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 197298.3075
Subtract 2000 from 2000 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
If we divide 0 by 400, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 197298.3075
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 14:
When dividing 0 by 400, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 197298.3075
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 197298.3075 with a remainder of 0.0.
