We're dividing 78172177 by 226 
We want to divide 78172177 by 226.

Advancing to step 1:
226 goes into 7 0 times 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.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 226

Step 2:
The number 226 fits into 78 0 times, leaving 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 (1) from the dividend, attach it to 78 and continue: 781 / 226

Moving on to step 3:
781 divided by 226 is 3 with a remainder of 103.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 678 from 781 and we're left with 103.
Include the next digit (7) from the dividend after 103, then repeat: 1037 / 226

Moving on to step 4:
1037 divided by 226 is 4 with a remainder of 133.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
The remainder is 133 after subtracting 904 from 1037.
Fetch the next digit (2) from the dividend, attach it to 133 and continue: 1332 / 226

Moving on to step 5:
When dividing 1332 by 226, we get 5 with a remainder of 202.
Use 5 as the next digit of our solution. 
Result so far: 345.0
Subtract 1130 from 1332 to get 202.
Grab the next digit (1) from the dividend, add it to 202, then carry on: 2021 / 226

Advancing to step 6:
226 can be fit into 2021 8 times, resulting in a remainder of 213.
Put 8 as the next digit of the answer. 
Result so far: 3458.0
If we take 1808 away from 2021, we end up with 213.
Fetch the next digit (7) from the dividend, attach it to 213 and continue: 2137 / 226

Advancing to step 7:
2137 divided by 226 is 9 with a remainder of 103.
The next digit of our result is 9. 
Result so far: 34589.0
If we subtract 2034 from 2137, we get 103.
Grab the next digit (7) from the dividend, add it to 103, then carry on: 1037 / 226

Let's proceed to step 8:
226 goes into 1037 4 times with a remainder of 133.
The number 4 becomes the next digit in our result. 
Result so far: 345894.0
If we subtract 904 from 1037, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 9:
226 goes into 1330 5 times with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 345894.5
The remainder is 200 after subtracting 1130 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
The number 226 fits into 2000 8 times, leaving a remainder of 192.
Record the quotient 8 as the next digit in the result. 
Result so far: 345894.58
If we take 1808 away from 2000, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 11:
226 goes into 1920 8 times with a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 345894.588
Subtracting 1808 from 1920 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Our division results in 345894.588 with a remaining 0.0112.
