We're dividing 10170021 by 101 
Let's see how many times 101 fits into 10170021.

Going ahead to step 1:
1 divided by 101 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 101

Step 2:
The number 101 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 101

Advancing to step 3:
If we divide 101 by 101, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 101 from 101 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 101

Going ahead to step 4:
The number 101 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 7 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 101

Advancing to step 5:
70 divided by 101 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we subtract 0 from 70, we get 70.
Append the next digit (0) from the dividend to 70 and continue with: 700 / 101

Let's proceed to step 6:
When dividing 700 by 101, we get 6 with a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 1006.0
Deduct 606 from 700 and we're left with 94.
Bring next digit (2) of the dividend behind the 94 and repeat the process: 942 / 101

Moving on to step 7:
When dividing 942 by 101, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 10069.0
If we subtract 909 from 942, we get 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 101

Going ahead to step 8:
101 can be fit into 331 3 times, resulting in a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 100693.0
Subtracting 303 from 331 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
If we divide 280 by 101, we get 2 and a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 100693.2
If we take 202 away from 280, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 10:
101 goes into 780 7 times with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 100693.27
If we subtract 707 from 780, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 11:
730 divided by 101 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 100693.277
Subtracting 707 from 730 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 100693.277 with a remainder of 0.0023.
