We look at the division of 79172 by 227 
We want to figure out the number of times 79172 can be divided by 227.

On to step 1:
227 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 227

Moving on to step 2:
79 divided by 227 is 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 227

Moving on to step 3:
If we divide 791 by 227, we get 3 and a remainder of 110.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 681 from 791 to get 110.
Take the next digit (7) from the dividend and append it to 110, then repeat: 1107 / 227

Moving on to step 4:
227 can be fit into 1107 4 times, resulting in a remainder of 199.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we take 908 away from 1107, we end up with 199.
Take the next digit (2) from the dividend and append it to 199, then repeat: 1992 / 227

Let's proceed to step 5:
1992 divided by 227 is 8 with a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 348.0
If we take 1816 away from 1992, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 6:
When dividing 1760 by 227, we get 7 with a remainder of 171.
The number 7 becomes the next digit in our result. 
Result so far: 348.7
Deduct 1589 from 1760 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 7:
1710 divided by 227 is 7 with a remainder of 121.
Put 7 as the next digit of the answer. 
Result so far: 348.77
If we take 1589 away from 1710, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

After the division, we end up with 348.77 and a remainder of 0.121.
