We look at the division of 79172 by 7 
We want to figure out the number of times 79172 can be divided by 7.

Moving on to step 1:
7 goes into 7 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 7 from 7 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 7

Advancing to step 2:
9 divided by 7 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 7 from 9 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 7

Moving on to step 3:
The number 7 fits into 21 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 113.0
The remainder is 0 after subtracting 21 from 21.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 7

Advancing to step 4:
If we divide 7 by 7, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1131.0
Deduct 7 from 7 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 7

Moving on to step 5:
2 divided by 7 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 11310.0
Subtract 0 from 2 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 6:
7 goes into 20 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 11310.2
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
When dividing 60 by 7, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 11310.28
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 11310.285
Subtracting 35 from 40 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 11310.2857
Deduct 49 from 50 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 11310.28571
Subtracting 7 from 10 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 11310.285714
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
20 divided by 7 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 11310.2857142
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
7 goes into 60 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 11310.28571428
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 11310.28571428 with a remaining 4e-09.
