We're dividing 78403104 by 217 
We're looking to find how many times 217 goes into 78403104.

Let's proceed to step 1:
If we divide 7 by 217, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 217

On to step 2:
When dividing 78 by 217, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 217

Moving on to step 3:
When dividing 784 by 217, we get 3 with a remainder of 133.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 651 away from 784, we end up with 133.
Append the next digit (0) from the dividend to 133 and continue with: 1330 / 217

Let's proceed to step 4:
217 can be fit into 1330 6 times, resulting in a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 1302 from 1330, we get 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 217

Step 5:
217 can be fit into 283 1 times, resulting in a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 361.0
Subtracting 217 from 283 leaves us with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 217

Step 6:
661 divided by 217 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3613.0
If we subtract 651 from 661, we get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 217

Advancing to step 7:
100 divided by 217 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 36130.0
The remainder is 100 after subtracting 0 from 100.
Bring next digit (4) of the dividend behind the 100 and repeat the process: 1004 / 217

On to step 8:
If we divide 1004 by 217, we get 4 and a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 361304.0
If we take 868 away from 1004, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 9:
The number 217 fits into 1360 6 times, leaving a remainder of 58.
The next digit of our result is 6. 
Result so far: 361304.6
Subtract 1302 from 1360 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
217 goes into 580 2 times with a remainder of 146.
The next digit of our result is 2. 
Result so far: 361304.62
The remainder is 146 after subtracting 434 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 11:
217 goes into 1460 6 times with a remainder of 158.
Use 6 as the next digit of our solution. 
Result so far: 361304.626
Subtracting 1302 from 1460 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 12:
217 goes into 1580 7 times with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 361304.6267
If we subtract 1519 from 1580, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 13:
The number 217 fits into 610 2 times, leaving a remainder of 176.
Write down 2 as next digit of the result. 
Result so far: 361304.62672
Subtract 434 from 610 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 14:
The number 217 fits into 1760 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 361304.626728
Deduct 1736 from 1760 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 15:
When dividing 240 by 217, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 361304.6267281
Subtract 217 from 240 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 16:
If we divide 230 by 217, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 361304.62672811
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 361304.62672811, with a leftover of 1.3e-08.
