45054648 ÷ 678 
We're looking to find how many times 678 goes into 45054648.

Let's proceed to step 1:
The number 678 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 678

On to step 2:
678 can be fit into 45 0 times, resulting in a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 678

Moving on to step 3:
678 can be fit into 450 0 times, resulting in a remainder of 450.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 450, we end up with 450.
Include the next digit (5) from the dividend after 450, then repeat: 4505 / 678

On to step 4:
678 can be fit into 4505 6 times, resulting in a remainder of 437.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 4068 from 4505 leaves us with 437.
Take the next digit (4) from the dividend and append it to 437, then repeat: 4374 / 678

Step 5:
When dividing 4374 by 678, we get 6 with a remainder of 306.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtract 4068 from 4374 to get 306.
Include the next digit (6) from the dividend after 306, then repeat: 3066 / 678

Let's proceed to step 6:
If we divide 3066 by 678, we get 4 and a remainder of 354.
Record the quotient 4 as the next digit in the result. 
Result so far: 664.0
Deduct 2712 from 3066 and we're left with 354.
Append the next digit (4) from the dividend to 354 and continue with: 3544 / 678

On to step 7:
If we divide 3544 by 678, we get 5 and a remainder of 154.
The number 5 becomes the next digit in our result. 
Result so far: 6645.0
Subtracting 3390 from 3544 leaves us with 154.
Append the next digit (8) from the dividend to 154 and continue with: 1548 / 678

Moving on to step 8:
If we divide 1548 by 678, we get 2 and a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 66452.0
Deduct 1356 from 1548 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 9:
678 goes into 1920 2 times with a remainder of 564.
Write down 2 as next digit of the result. 
Result so far: 66452.2
Subtract 1356 from 1920 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 10:
678 can be fit into 5640 8 times, resulting in a remainder of 216.
Use 8 as the next digit of our solution. 
Result so far: 66452.28
Deduct 5424 from 5640 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 11:
When dividing 2160 by 678, we get 3 with a remainder of 126.
Record the quotient 3 as the next digit in the result. 
Result so far: 66452.283
Subtract 2034 from 2160 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 12:
The number 678 fits into 1260 1 times, leaving a remainder of 582.
Record the quotient 1 as the next digit in the result. 
Result so far: 66452.2831
Subtract 678 from 1260 to get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Step 13:
When dividing 5820 by 678, we get 8 with a remainder of 396.
Record the quotient 8 as the next digit in the result. 
Result so far: 66452.28318
Subtracting 5424 from 5820 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 14:
3960 divided by 678 is 5 with a remainder of 570.
Record the quotient 5 as the next digit in the result. 
Result so far: 66452.283185
Subtracting 3390 from 3960 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 15:
678 can be fit into 5700 8 times, resulting in a remainder of 276.
Use 8 as the next digit of our solution. 
Result so far: 66452.2831858
Deduct 5424 from 5700 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 16:
2760 divided by 678 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 66452.28318584
The remainder is 48 after subtracting 2712 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 66452.28318584 with a remaining 4.8e-08.
