We're dividing 78649030 by 200 
We want to divide 78649030 by 200.

Advancing to step 1:
200 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 200

Let's proceed to step 2:
200 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
Subtracting 0 from 78 leaves us with 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 200

Let's proceed to step 3:
200 goes into 786 3 times with a remainder of 186.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 186 after subtracting 600 from 786.
Append the next digit (4) from the dividend to 186 and continue with: 1864 / 200

On to step 4:
200 can be fit into 1864 9 times, resulting in a remainder of 64.
The next digit of our result is 9. 
Result so far: 39.0
If we take 1800 away from 1864, we end up with 64.
Append the next digit (9) from the dividend to 64 and continue with: 649 / 200

Moving on to step 5:
200 can be fit into 649 3 times, resulting in a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 393.0
The remainder is 49 after subtracting 600 from 649.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 200

Going ahead to step 6:
When dividing 490 by 200, we get 2 with a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 3932.0
Deduct 400 from 490 and we're left with 90.
Bring next digit (3) of the dividend behind the 90 and repeat the process: 903 / 200

On to step 7:
903 divided by 200 is 4 with a remainder of 103.
Put 4 as the next digit of the answer. 
Result so far: 39324.0
Subtract 800 from 903 to get 103.
Grab the next digit (0) from the dividend, add it to 103, then carry on: 1030 / 200

On to step 8:
200 goes into 1030 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 393245.0
If we take 1000 away from 1030, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
The number 200 fits into 300 1 times, leaving a remainder of 100.
Record the quotient 1 as the next digit in the result. 
Result so far: 393245.1
If we take 200 away from 300, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 10:
200 goes into 1000 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 393245.15
Subtracting 1000 from 1000 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.

Moving on to step 11:
200 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 393245.15
If we take 0 away from 0, we end up 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:
200 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 393245.15
If we take 0 away from 0, we end up 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.

The final outcome is 393245.15, with a leftover of 0.0.
