78181715 divided by 371 
We want to divide 78181715 by 371.

Let's proceed to step 1:
371 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 371

Moving on to step 2:
371 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 371

Let's proceed to step 3:
371 can be fit into 781 2 times, resulting in a remainder of 39.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 742 from 781 leaves us with 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 371

Going ahead to step 4:
371 can be fit into 398 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 371 from 398, we get 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 371

Advancing to step 5:
The number 371 fits into 271 0 times, leaving a remainder of 271.
Write down 0 as next digit of the result. 
Result so far: 210.0
Subtract 0 from 271 to get 271.
Include the next digit (7) from the dividend after 271, then repeat: 2717 / 371

Advancing to step 6:
The number 371 fits into 2717 7 times, leaving a remainder of 120.
The number 7 becomes the next digit in our result. 
Result so far: 2107.0
Subtract 2597 from 2717 to get 120.
Include the next digit (1) from the dividend after 120, then repeat: 1201 / 371

Going ahead to step 7:
1201 divided by 371 is 3 with a remainder of 88.
Write down 3 as next digit of the result. 
Result so far: 21073.0
Subtracting 1113 from 1201 leaves us with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 371

Going ahead to step 8:
371 goes into 885 2 times with a remainder of 143.
Write down 2 as next digit of the result. 
Result so far: 210732.0
If we take 742 away from 885, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 9:
371 can be fit into 1430 3 times, resulting in a remainder of 317.
Use 3 as the next digit of our solution. 
Result so far: 210732.3
If we subtract 1113 from 1430, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 10:
371 goes into 3170 8 times with a remainder of 202.
Put 8 as the next digit of the answer. 
Result so far: 210732.38
If we subtract 2968 from 3170, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 11:
If we divide 2020 by 371, we get 5 and a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 210732.385
The remainder is 165 after subtracting 1855 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 12:
If we divide 1650 by 371, we get 4 and a remainder of 166.
Put 4 as the next digit of the answer. 
Result so far: 210732.3854
The remainder is 166 after subtracting 1484 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 13:
The number 371 fits into 1660 4 times, leaving a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 210732.38544
Deduct 1484 from 1660 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final outcome is 210732.38544, with a leftover of 0.000176.
