54050172 divided by 678 
We want to figure out the number of times 54050172 can be divided by 678.

Going ahead to step 1:
When dividing 5 by 678, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 678

Step 2:
The number 678 fits into 54 0 times, leaving a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (0) from the dividend to 54 and continue with: 540 / 678

Going ahead to step 3:
540 divided by 678 is 0 with a remainder of 540.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 540 and we're left with 540.
Append the next digit (5) from the dividend to 540 and continue with: 5405 / 678

Advancing to step 4:
678 goes into 5405 7 times with a remainder of 659.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4746 from 5405, we get 659.
Grab the next digit (0) from the dividend, add it to 659, then carry on: 6590 / 678

Let's proceed to step 5:
The number 678 fits into 6590 9 times, leaving a remainder of 488.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
The remainder is 488 after subtracting 6102 from 6590.
Bring next digit (1) of the dividend behind the 488 and repeat the process: 4881 / 678

Step 6:
678 goes into 4881 7 times with a remainder of 135.
Record the quotient 7 as the next digit in the result. 
Result so far: 797.0
Deduct 4746 from 4881 and we're left with 135.
Fetch the next digit (7) from the dividend, attach it to 135 and continue: 1357 / 678

Step 7:
678 can be fit into 1357 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 7972.0
Deduct 1356 from 1357 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 678

Let's proceed to step 8:
678 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 79720.0
If we take 0 away from 12, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
678 can be fit into 120 0 times, resulting in a remainder of 120.
The next digit of our result is 0. 
Result so far: 79720.0
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
If we divide 1200 by 678, we get 1 and a remainder of 522.
Write down 1 as next digit of the result. 
Result so far: 79720.01
Subtracting 678 from 1200 leaves us with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Going ahead to step 11:
If we divide 5220 by 678, we get 7 and a remainder of 474.
Use 7 as the next digit of our solution. 
Result so far: 79720.017
If we take 4746 away from 5220, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 12:
678 can be fit into 4740 6 times, resulting in a remainder of 672.
The number 6 becomes the next digit in our result. 
Result so far: 79720.0176
Subtract 4068 from 4740 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Advancing to step 13:
678 goes into 6720 9 times with a remainder of 618.
Use 9 as the next digit of our solution. 
Result so far: 79720.01769
Deduct 6102 from 6720 and we're left with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Step 14:
6180 divided by 678 is 9 with a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 79720.017699
If we take 6102 away from 6180, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 79720.017699 and a remainder of 7.8e-06.
