We're dividing 17122790 by 173 
Our goal is to divide 17122790 by 173.

On to step 1:
The number 173 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 173

Advancing to step 2:
If we divide 17 by 173, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 173

Advancing to step 3:
When dividing 171 by 173, we get 0 with a remainder of 171.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 171 after subtracting 0 from 171.
Include the next digit (2) from the dividend after 171, then repeat: 1712 / 173

Moving on to step 4:
The number 173 fits into 1712 9 times, leaving a remainder of 155.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 1557 away from 1712, we end up with 155.
Append the next digit (2) from the dividend to 155 and continue with: 1552 / 173

Let's proceed to step 5:
173 goes into 1552 8 times with a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtracting 1384 from 1552 leaves us with 168.
Bring next digit (7) of the dividend behind the 168 and repeat the process: 1687 / 173

Step 6:
When dividing 1687 by 173, we get 9 with a remainder of 130.
Put 9 as the next digit of the answer. 
Result so far: 989.0
Subtract 1557 from 1687 to get 130.
Append the next digit (9) from the dividend to 130 and continue with: 1309 / 173

Advancing to step 7:
If we divide 1309 by 173, we get 7 and a remainder of 98.
Record the quotient 7 as the next digit in the result. 
Result so far: 9897.0
If we subtract 1211 from 1309, we get 98.
Grab the next digit (0) from the dividend, add it to 98, then carry on: 980 / 173

Advancing to step 8:
When dividing 980 by 173, we get 5 with a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 98975.0
The remainder is 115 after subtracting 865 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 9:
173 goes into 1150 6 times with a remainder of 112.
The next digit of our result is 6. 
Result so far: 98975.6
Deduct 1038 from 1150 and we're left 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.

Step 10:
If we divide 1120 by 173, we get 6 and a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 98975.66
Deduct 1038 from 1120 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

After the division, we end up with 98975.66 and a remainder of 0.082.
