We divide 78286634 by 207
We want to divide 78286634 by 207.

Moving on to step 1:
If we divide 7 by 207, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 207

Advancing to step 2:
When dividing 78 by 207, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 207

On to step 3:
When dividing 782 by 207, we get 3 with a remainder of 161.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 161 after subtracting 621 from 782.
Include the next digit (8) from the dividend after 161, then repeat: 1618 / 207

On to step 4:
207 can be fit into 1618 7 times, resulting in a remainder of 169.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtracting 1449 from 1618 leaves us with 169.
Include the next digit (6) from the dividend after 169, then repeat: 1696 / 207

On to step 5:
If we divide 1696 by 207, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 378.0
If we subtract 1656 from 1696, we get 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 207

Let's proceed to step 6:
207 can be fit into 406 1 times, resulting in a remainder of 199.
Write down 1 as next digit of the result. 
Result so far: 3781.0
Deduct 207 from 406 and we're left with 199.
Grab the next digit (3) from the dividend, add it to 199, then carry on: 1993 / 207

Let's proceed to step 7:
1993 divided by 207 is 9 with a remainder of 130.
Put 9 as the next digit of the answer. 
Result so far: 37819.0
The remainder is 130 after subtracting 1863 from 1993.
Append the next digit (4) from the dividend to 130 and continue with: 1304 / 207

Step 8:
207 can be fit into 1304 6 times, resulting in a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 378196.0
Deduct 1242 from 1304 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
207 goes into 620 2 times with a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 378196.2
If we subtract 414 from 620, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 10:
The number 207 fits into 2060 9 times, leaving a remainder of 197.
The next digit of our result is 9. 
Result so far: 378196.29
The remainder is 197 after subtracting 1863 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 11:
207 can be fit into 1970 9 times, resulting in a remainder of 107.
The number 9 becomes the next digit in our result. 
Result so far: 378196.299
If we take 1863 away from 1970, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

The final outcome is 378196.299, with a leftover of 0.0107.
