We look at the division of 38678784 by 451 
We're looking to find how many times 451 goes into 38678784.

On to step 1:
If we divide 3 by 451, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 451

Step 2:
451 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 451

Step 3:
386 divided by 451 is 0 with a remainder of 386.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 386, we end up with 386.
Include the next digit (7) from the dividend after 386, then repeat: 3867 / 451

Moving on to step 4:
If we divide 3867 by 451, we get 8 and a remainder of 259.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 3608 from 3867 leaves us with 259.
Bring next digit (8) of the dividend behind the 259 and repeat the process: 2598 / 451

Advancing to step 5:
451 can be fit into 2598 5 times, resulting in a remainder of 343.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtracting 2255 from 2598 leaves us with 343.
Bring next digit (7) of the dividend behind the 343 and repeat the process: 3437 / 451

Step 6:
If we divide 3437 by 451, we get 7 and a remainder of 280.
Record the quotient 7 as the next digit in the result. 
Result so far: 857.0
If we subtract 3157 from 3437, we get 280.
Grab the next digit (8) from the dividend, add it to 280, then carry on: 2808 / 451

Advancing to step 7:
When dividing 2808 by 451, we get 6 with a remainder of 102.
The next digit of our result is 6. 
Result so far: 8576.0
Subtracting 2706 from 2808 leaves us with 102.
Include the next digit (4) from the dividend after 102, then repeat: 1024 / 451

Moving on to step 8:
1024 divided by 451 is 2 with a remainder of 122.
Use 2 as the next digit of our solution. 
Result so far: 85762.0
If we subtract 902 from 1024, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 9:
When dividing 1220 by 451, we get 2 with a remainder of 318.
Put 2 as the next digit of the answer. 
Result so far: 85762.2
If we subtract 902 from 1220, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 10:
3180 divided by 451 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 85762.27
Deduct 3157 from 3180 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 11:
451 goes into 230 0 times with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 85762.27
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 12:
If we divide 2300 by 451, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 85762.2705
Deduct 2255 from 2300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 13:
The number 451 fits into 450 0 times, leaving a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 85762.2705
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 14:
451 can be fit into 4500 9 times, resulting in a remainder of 441.
Write down 9 as next digit of the result. 
Result so far: 85762.270509
Subtracting 4059 from 4500 leaves us with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

On to step 15:
4410 divided by 451 is 9 with a remainder of 351.
The number 9 becomes the next digit in our result. 
Result so far: 85762.2705099
If we subtract 4059 from 4410, we get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

The final outcome is 85762.2705099, with a leftover of 3.51e-06.
