We're dividing 2171901 by 173 
We're looking to find how many times 173 goes into 2171901.

Advancing to step 1:
2 divided by 173 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 173

Step 2:
The number 173 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 173

Moving on to step 3:
217 divided by 173 is 1 with a remainder of 44.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 173 from 217 leaves us with 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 173

Let's proceed to step 4:
When dividing 441 by 173, we get 2 with a remainder of 95.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 346 from 441 leaves us with 95.
Grab the next digit (9) from the dividend, add it to 95, then carry on: 959 / 173

On to step 5:
173 can be fit into 959 5 times, resulting in a remainder of 94.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
The remainder is 94 after subtracting 865 from 959.
Bring next digit (0) of the dividend behind the 94 and repeat the process: 940 / 173

Going ahead to step 6:
If we divide 940 by 173, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 1255.0
Deduct 865 from 940 and we're left with 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 173

Step 7:
173 goes into 751 4 times with a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 12554.0
Deduct 692 from 751 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 8:
The number 173 fits into 590 3 times, leaving a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 12554.3
Subtract 519 from 590 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
710 divided by 173 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 12554.34
If we take 692 away from 710, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
If we divide 180 by 173, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 12554.341
If we subtract 173 from 180, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
The number 173 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 12554.341
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
The number 173 fits into 700 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 12554.34104
The remainder is 8 after subtracting 692 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
The number 173 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 12554.34104
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
173 can be fit into 800 4 times, resulting in a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 12554.3410404
If we subtract 692 from 800, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 15:
The number 173 fits into 1080 6 times, leaving a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 12554.34104046
If we subtract 1038 from 1080, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 12554.34104046 with a remaining 4.2e-08.
