We look at the division of 81543741 by 780 
Our goal is to divide 81543741 by 780.

On to step 1:
780 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 780

Step 2:
780 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 780

Moving on to step 3:
780 goes into 815 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 780 from 815, we get 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 780

Going ahead to step 4:
The number 780 fits into 354 0 times, leaving a remainder of 354.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 354 and we're left with 354.
Fetch the next digit (3) from the dividend, attach it to 354 and continue: 3543 / 780

Step 5:
When dividing 3543 by 780, we get 4 with a remainder of 423.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Subtract 3120 from 3543 to get 423.
Append the next digit (7) from the dividend to 423 and continue with: 4237 / 780

Advancing to step 6:
780 can be fit into 4237 5 times, resulting in a remainder of 337.
The number 5 becomes the next digit in our result. 
Result so far: 1045.0
Subtracting 3900 from 4237 leaves us with 337.
Append the next digit (4) from the dividend to 337 and continue with: 3374 / 780

Moving on to step 7:
If we divide 3374 by 780, we get 4 and a remainder of 254.
Write down 4 as next digit of the result. 
Result so far: 10454.0
If we take 3120 away from 3374, we end up with 254.
Append the next digit (1) from the dividend to 254 and continue with: 2541 / 780

Step 8:
780 goes into 2541 3 times with a remainder of 201.
Put 3 as the next digit of the answer. 
Result so far: 104543.0
If we take 2340 away from 2541, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 9:
780 can be fit into 2010 2 times, resulting in a remainder of 450.
Use 2 as the next digit of our solution. 
Result so far: 104543.2
Subtracting 1560 from 2010 leaves us with 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 10:
780 can be fit into 4500 5 times, resulting in a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 104543.25
The remainder is 600 after subtracting 3900 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 11:
The number 780 fits into 6000 7 times, leaving a remainder of 540.
The next digit of our result is 7. 
Result so far: 104543.257
Subtracting 5460 from 6000 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 12:
780 goes into 5400 6 times with a remainder of 720.
Use 6 as the next digit of our solution. 
Result so far: 104543.2576
Subtract 4680 from 5400 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 13:
When dividing 7200 by 780, we get 9 with a remainder of 180.
Record the quotient 9 as the next digit in the result. 
Result so far: 104543.25769
Deduct 7020 from 7200 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 14:
If we divide 1800 by 780, we get 2 and a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 104543.257692
If we take 1560 away from 1800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 15:
When dividing 2400 by 780, we get 3 with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 104543.2576923
Subtracting 2340 from 2400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 16:
780 can be fit into 600 0 times, resulting in a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 104543.2576923
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 104543.2576923 with a remaining 6e-07.
