We're dividing 2115424 by 172 
We're looking to find how many times 172 goes into 2115424.

On to step 1:
172 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 172

Let's proceed to step 2:
If we divide 21 by 172, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 172

Let's proceed to step 3:
211 divided by 172 is 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 172 from 211 leaves us with 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 172

Step 4:
If we divide 395 by 172, we get 2 and a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 344 from 395 to get 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 172

Going ahead to step 5:
514 divided by 172 is 2 with a remainder of 170.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Subtracting 344 from 514 leaves us with 170.
Grab the next digit (2) from the dividend, add it to 170, then carry on: 1702 / 172

Going ahead to step 6:
1702 divided by 172 is 9 with a remainder of 154.
The next digit of our result is 9. 
Result so far: 1229.0
If we subtract 1548 from 1702, we get 154.
Grab the next digit (4) from the dividend, add it to 154, then carry on: 1544 / 172

Let's proceed to step 7:
172 goes into 1544 8 times with a remainder of 168.
The number 8 becomes the next digit in our result. 
Result so far: 12298.0
If we subtract 1376 from 1544, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 8:
The number 172 fits into 1680 9 times, leaving a remainder of 132.
The number 9 becomes the next digit in our result. 
Result so far: 12298.9
Subtract 1548 from 1680 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 9:
172 can be fit into 1320 7 times, resulting in a remainder of 116.
Record the quotient 7 as the next digit in the result. 
Result so far: 12298.97
If we subtract 1204 from 1320, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 10:
The number 172 fits into 1160 6 times, leaving a remainder of 128.
The next digit of our result is 6. 
Result so far: 12298.976
If we take 1032 away from 1160, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 11:
If we divide 1280 by 172, we get 7 and a remainder of 76.
The next digit of our result is 7. 
Result so far: 12298.9767
The remainder is 76 after subtracting 1204 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 12:
172 goes into 760 4 times with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 12298.97674
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 13:
172 goes into 720 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 12298.976744
Subtracting 688 from 720 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 12298.976744, with a leftover of 3.2e-06.
