We divide 78684540 by 217
We want to figure out the number of times 78684540 can be divided by 217.

Let's proceed to step 1:
When dividing 7 by 217, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 217

Going ahead to step 2:
If we divide 78 by 217, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 217

Let's proceed to step 3:
The number 217 fits into 786 3 times, leaving a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 651 from 786 to get 135.
Append the next digit (8) from the dividend to 135 and continue with: 1358 / 217

Step 4:
When dividing 1358 by 217, we get 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we subtract 1302 from 1358, we get 56.
Append the next digit (4) from the dividend to 56 and continue with: 564 / 217

On to step 5:
When dividing 564 by 217, we get 2 with a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 362.0
Subtracting 434 from 564 leaves us with 130.
Include the next digit (5) from the dividend after 130, then repeat: 1305 / 217

Going ahead to step 6:
217 can be fit into 1305 6 times, resulting in a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 3626.0
If we subtract 1302 from 1305, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 217

Moving on to step 7:
If we divide 34 by 217, we get 0 and a remainder of 34.
The next digit of our result is 0. 
Result so far: 36260.0
Subtract 0 from 34 to get 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 217

Going ahead to step 8:
If we divide 340 by 217, we get 1 and a remainder of 123.
The next digit of our result is 1. 
Result so far: 362601.0
If we take 217 away from 340, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 9:
217 goes into 1230 5 times with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 362601.5
Subtract 1085 from 1230 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 10:
217 can be fit into 1450 6 times, resulting in a remainder of 148.
Use 6 as the next digit of our solution. 
Result so far: 362601.56
Subtract 1302 from 1450 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 11:
If we divide 1480 by 217, we get 6 and a remainder of 178.
Put 6 as the next digit of the answer. 
Result so far: 362601.566
The remainder is 178 after subtracting 1302 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

After the division, we end up with 362601.566 and a remainder of 0.0178.
