54087811 divided by 781 
We're looking to find how many times 781 goes into 54087811.

Step 1:
When dividing 5 by 781, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 781

Moving on to step 2:
The number 781 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Bring next digit (0) of the dividend behind the 54 and repeat the process: 540 / 781

Let's proceed to step 3:
781 can be fit into 540 0 times, resulting in a remainder of 540.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 540, we end up with 540.
Take the next digit (8) from the dividend and append it to 540, then repeat: 5408 / 781

Step 4:
5408 divided by 781 is 6 with a remainder of 722.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 4686 from 5408 leaves us with 722.
Append the next digit (7) from the dividend to 722 and continue with: 7227 / 781

Let's proceed to step 5:
781 goes into 7227 9 times with a remainder of 198.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
The remainder is 198 after subtracting 7029 from 7227.
Bring next digit (8) of the dividend behind the 198 and repeat the process: 1988 / 781

Step 6:
If we divide 1988 by 781, we get 2 and a remainder of 426.
Write down 2 as next digit of the result. 
Result so far: 692.0
Subtract 1562 from 1988 to get 426.
Append the next digit (1) from the dividend to 426 and continue with: 4261 / 781

Let's proceed to step 7:
4261 divided by 781 is 5 with a remainder of 356.
The next digit of our result is 5. 
Result so far: 6925.0
The remainder is 356 after subtracting 3905 from 4261.
Grab the next digit (1) from the dividend, add it to 356, then carry on: 3561 / 781

Moving on to step 8:
781 can be fit into 3561 4 times, resulting in a remainder of 437.
Use 4 as the next digit of our solution. 
Result so far: 69254.0
Deduct 3124 from 3561 and we're left with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Going ahead to step 9:
When dividing 4370 by 781, we get 5 with a remainder of 465.
The next digit of our result is 5. 
Result so far: 69254.5
Subtract 3905 from 4370 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Moving on to step 10:
781 goes into 4650 5 times with a remainder of 745.
Write down 5 as next digit of the result. 
Result so far: 69254.55
Subtract 3905 from 4650 to get 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Our division results in 69254.55 with a remaining 0.745.
