78809038 divided by 400 
We want to figure out the number of times 78809038 can be divided by 400.

On to step 1:
The number 400 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 400

Let's proceed to step 2:
400 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 400

Let's proceed to step 3:
If we divide 788 by 400, we get 1 and a remainder of 388.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 388 after subtracting 400 from 788.
Fetch the next digit (0) from the dividend, attach it to 388 and continue: 3880 / 400

Let's proceed to step 4:
400 can be fit into 3880 9 times, resulting in a remainder of 280.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 3600 from 3880 leaves us with 280.
Append the next digit (9) from the dividend to 280 and continue with: 2809 / 400

Going ahead to step 5:
The number 400 fits into 2809 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
If we subtract 2800 from 2809, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 400

Let's proceed to step 6:
400 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 1970.0
If we take 0 away from 90, we end up with 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 400

On to step 7:
When dividing 903 by 400, we get 2 with a remainder of 103.
The next digit of our result is 2. 
Result so far: 19702.0
If we subtract 800 from 903, we get 103.
Append the next digit (8) from the dividend to 103 and continue with: 1038 / 400

Let's proceed to step 8:
When dividing 1038 by 400, we get 2 with a remainder of 238.
The number 2 becomes the next digit in our result. 
Result so far: 197022.0
Deduct 800 from 1038 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 9:
The number 400 fits into 2380 5 times, leaving a remainder of 380.
Write down 5 as next digit of the result. 
Result so far: 197022.5
If we take 2000 away from 2380, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 10:
The number 400 fits into 3800 9 times, leaving a remainder of 200.
Use 9 as the next digit of our solution. 
Result so far: 197022.59
Subtracting 3600 from 3800 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
If we divide 2000 by 400, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 197022.595
Deduct 2000 from 2000 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.

On to step 12:
0 divided by 400 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 197022.595
Subtracting 0 from 0 leaves us 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.

On to step 13:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 197022.595
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.

Our division results in 197022.595 with a remaining 0.0.
