Let's divide 71374813 by 780
Our goal is to divide 71374813 by 780.

Moving on to step 1:
If we divide 7 by 780, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 780

Step 2:
71 divided by 780 is 0 with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Append the next digit (3) from the dividend to 71 and continue with: 713 / 780

Going ahead to step 3:
713 divided by 780 is 0 with a remainder of 713.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 713 leaves us with 713.
Append the next digit (7) from the dividend to 713 and continue with: 7137 / 780

Moving on to step 4:
The number 780 fits into 7137 9 times, leaving a remainder of 117.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 7020 from 7137 and we're left with 117.
Grab the next digit (4) from the dividend, add it to 117, then carry on: 1174 / 780

On to step 5:
780 goes into 1174 1 times with a remainder of 394.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we subtract 780 from 1174, we get 394.
Include the next digit (8) from the dividend after 394, then repeat: 3948 / 780

Moving on to step 6:
If we divide 3948 by 780, we get 5 and a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 915.0
Deduct 3900 from 3948 and we're left with 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 780

Advancing to step 7:
481 divided by 780 is 0 with a remainder of 481.
The number 0 becomes the next digit in our result. 
Result so far: 9150.0
Deduct 0 from 481 and we're left with 481.
Grab the next digit (3) from the dividend, add it to 481, then carry on: 4813 / 780

On to step 8:
The number 780 fits into 4813 6 times, leaving a remainder of 133.
Use 6 as the next digit of our solution. 
Result so far: 91506.0
Deduct 4680 from 4813 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 9:
1330 divided by 780 is 1 with a remainder of 550.
Write down 1 as next digit of the result. 
Result so far: 91506.1
The remainder is 550 after subtracting 780 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 10:
780 goes into 5500 7 times with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 91506.17
Deduct 5460 from 5500 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
780 goes into 400 0 times with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 91506.17
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.

On to step 12:
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: 91506.1705
Subtract 3900 from 4000 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
The number 780 fits into 1000 1 times, leaving a remainder of 220.
Write down 1 as next digit of the result. 
Result so far: 91506.17051
Subtracting 780 from 1000 leaves us 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 14:
780 can be fit into 2200 2 times, resulting in a remainder of 640.
The next digit of our result is 2. 
Result so far: 91506.170512
If we take 1560 away from 2200, 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.

Step 15:
6400 divided by 780 is 8 with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 91506.1705128
Deduct 6240 from 6400 and we're left 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.

Going ahead to step 16:
When dividing 1600 by 780, we get 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 91506.17051282
If we take 1560 away from 1600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 91506.17051282, with a leftover of 4e-08.
