78722769 divided by 217 
We want to figure out the number of times 78722769 can be divided by 217.

Going ahead to step 1:
If we divide 7 by 217, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 217

Step 2:
217 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 217

Moving on to step 3:
When dividing 787 by 217, we get 3 with a remainder of 136.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 651 from 787, we get 136.
Append the next digit (2) from the dividend to 136 and continue with: 1362 / 217

Step 4:
217 can be fit into 1362 6 times, resulting in a remainder of 60.
The next digit of our result is 6. 
Result so far: 36.0
If we take 1302 away from 1362, we end up with 60.
Take the next digit (2) from the dividend and append it to 60, then repeat: 602 / 217

Moving on to step 5:
When dividing 602 by 217, we get 2 with a remainder of 168.
Put 2 as the next digit of the answer. 
Result so far: 362.0
The remainder is 168 after subtracting 434 from 602.
Grab the next digit (7) from the dividend, add it to 168, then carry on: 1687 / 217

Moving on to step 6:
When dividing 1687 by 217, we get 7 with a remainder of 168.
Use 7 as the next digit of our solution. 
Result so far: 3627.0
Deduct 1519 from 1687 and we're left with 168.
Grab the next digit (6) from the dividend, add it to 168, then carry on: 1686 / 217

On to step 7:
If we divide 1686 by 217, we get 7 and a remainder of 167.
Use 7 as the next digit of our solution. 
Result so far: 36277.0
If we take 1519 away from 1686, we end up with 167.
Include the next digit (9) from the dividend after 167, then repeat: 1679 / 217

Step 8:
The number 217 fits into 1679 7 times, leaving a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 362777.0
Subtract 1519 from 1679 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 9:
1600 divided by 217 is 7 with a remainder of 81.
The next digit of our result is 7. 
Result so far: 362777.7
The remainder is 81 after subtracting 1519 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 10:
If we divide 810 by 217, we get 3 and a remainder of 159.
Write down 3 as next digit of the result. 
Result so far: 362777.73
Subtract 651 from 810 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 11:
When dividing 1590 by 217, we get 7 with a remainder of 71.
The next digit of our result is 7. 
Result so far: 362777.737
Subtracting 1519 from 1590 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 12:
710 divided by 217 is 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 362777.7373
Subtract 651 from 710 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 13:
217 can be fit into 590 2 times, resulting in a remainder of 156.
The number 2 becomes the next digit in our result. 
Result so far: 362777.73732
If we take 434 away from 590, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 14:
1560 divided by 217 is 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 362777.737327
The remainder is 41 after subtracting 1519 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 15:
217 goes into 410 1 times with a remainder of 193.
Put 1 as the next digit of the answer. 
Result so far: 362777.7373271
Subtract 217 from 410 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 16:
217 can be fit into 1930 8 times, resulting in a remainder of 194.
Write down 8 as next digit of the result. 
Result so far: 362777.73732718
Subtracting 1736 from 1930 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The final outcome is 362777.73732718, with a leftover of 1.94e-07.
