51845572 ÷ 780 
We want to divide 51845572 by 780.

Going ahead to step 1:
5 divided by 780 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 780

Advancing to step 2:
When dividing 51 by 780, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 780

On to step 3:
518 divided by 780 is 0 with a remainder of 518.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 518 and we're left with 518.
Take the next digit (4) from the dividend and append it to 518, then repeat: 5184 / 780

Let's proceed to step 4:
780 goes into 5184 6 times with a remainder of 504.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 4680 from 5184 to get 504.
Grab the next digit (5) from the dividend, add it to 504, then carry on: 5045 / 780

Moving on to step 5:
The number 780 fits into 5045 6 times, leaving a remainder of 365.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we subtract 4680 from 5045, we get 365.
Take the next digit (5) from the dividend and append it to 365, then repeat: 3655 / 780

Moving on to step 6:
780 can be fit into 3655 4 times, resulting in a remainder of 535.
Write down 4 as next digit of the result. 
Result so far: 664.0
If we subtract 3120 from 3655, we get 535.
Include the next digit (7) from the dividend after 535, then repeat: 5357 / 780

Step 7:
780 can be fit into 5357 6 times, resulting in a remainder of 677.
Use 6 as the next digit of our solution. 
Result so far: 6646.0
Deduct 4680 from 5357 and we're left with 677.
Bring next digit (2) of the dividend behind the 677 and repeat the process: 6772 / 780

Going ahead to step 8:
The number 780 fits into 6772 8 times, leaving a remainder of 532.
Use 8 as the next digit of our solution. 
Result so far: 66468.0
Deduct 6240 from 6772 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 9:
If we divide 5320 by 780, we get 6 and a remainder of 640.
Record the quotient 6 as the next digit in the result. 
Result so far: 66468.6
If we take 4680 away from 5320, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 10:
The number 780 fits into 6400 8 times, leaving a remainder of 160.
The next digit of our result is 8. 
Result so far: 66468.68
The remainder is 160 after subtracting 6240 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
1600 divided by 780 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 66468.682
The remainder is 40 after subtracting 1560 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
The number 780 fits into 400 0 times, leaving a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 66468.682
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
If we divide 4000 by 780, we get 5 and a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 66468.68205
Deduct 3900 from 4000 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 14:
When dividing 1000 by 780, we get 1 with a remainder of 220.
Record the quotient 1 as the next digit in the result. 
Result so far: 66468.682051
If we take 780 away from 1000, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 15:
When dividing 2200 by 780, we get 2 with a remainder of 640.
Put 2 as the next digit of the answer. 
Result so far: 66468.6820512
The remainder is 640 after subtracting 1560 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 16:
780 goes into 6400 8 times with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 66468.68205128
Subtracting 6240 from 6400 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 66468.68205128 with a remainder of 1.6e-07.
