78513094 divided by 215 
Our goal is to divide 78513094 by 215.

Let's proceed to step 1:
7 divided by 215 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 215

On to step 2:
78 divided by 215 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 215

Advancing to step 3:
215 goes into 785 3 times with a remainder of 140.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 140 after subtracting 645 from 785.
Fetch the next digit (1) from the dividend, attach it to 140 and continue: 1401 / 215

Advancing to step 4:
215 goes into 1401 6 times with a remainder of 111.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we subtract 1290 from 1401, we get 111.
Append the next digit (3) from the dividend to 111 and continue with: 1113 / 215

Going ahead to step 5:
215 goes into 1113 5 times with a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 365.0
Deduct 1075 from 1113 and we're left with 38.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 215

Advancing to step 6:
The number 215 fits into 380 1 times, leaving a remainder of 165.
Use 1 as the next digit of our solution. 
Result so far: 3651.0
The remainder is 165 after subtracting 215 from 380.
Bring next digit (9) of the dividend behind the 165 and repeat the process: 1659 / 215

Advancing to step 7:
1659 divided by 215 is 7 with a remainder of 154.
Record the quotient 7 as the next digit in the result. 
Result so far: 36517.0
If we take 1505 away from 1659, we end up with 154.
Bring next digit (4) of the dividend behind the 154 and repeat the process: 1544 / 215

Going ahead to step 8:
1544 divided by 215 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 365177.0
Deduct 1505 from 1544 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
The number 215 fits into 390 1 times, leaving a remainder of 175.
The next digit of our result is 1. 
Result so far: 365177.1
Deduct 215 from 390 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 10:
215 can be fit into 1750 8 times, resulting in a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 365177.18
Deduct 1720 from 1750 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
If we divide 300 by 215, we get 1 and a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 365177.181
If we subtract 215 from 300, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 12:
The number 215 fits into 850 3 times, leaving a remainder of 205.
The next digit of our result is 3. 
Result so far: 365177.1813
If we subtract 645 from 850, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 13:
The number 215 fits into 2050 9 times, leaving a remainder of 115.
Use 9 as the next digit of our solution. 
Result so far: 365177.18139
If we subtract 1935 from 2050, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 14:
If we divide 1150 by 215, we get 5 and a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 365177.181395
If we subtract 1075 from 1150, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 15:
215 goes into 750 3 times with a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 365177.1813953
Subtracting 645 from 750 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 16:
215 goes into 1050 4 times with a remainder of 190.
Use 4 as the next digit of our solution. 
Result so far: 365177.18139534
Subtracting 860 from 1050 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Our division results in 365177.18139534 with a remaining 1.9e-07.
