172951 ÷ 79 
We're looking to find how many times 79 goes into 172951.

On to step 1:
The number 79 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 79

Going ahead to step 2:
17 divided by 79 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 79

Step 3:
If we divide 172 by 79, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 158 away from 172, we end up with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 79

Let's proceed to step 4:
149 divided by 79 is 1 with a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 79 from 149, we get 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 79

Going ahead to step 5:
79 goes into 705 8 times with a remainder of 73.
The next digit of our result is 8. 
Result so far: 218.0
Subtract 632 from 705 to get 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 79

Let's proceed to step 6:
79 goes into 731 9 times with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 2189.0
Subtract 711 from 731 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
When dividing 200 by 79, we get 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 2189.2
The remainder is 42 after subtracting 158 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
79 goes into 420 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 2189.25
Subtract 395 from 420 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
79 goes into 250 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 2189.253
Subtract 237 from 250 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
79 can be fit into 130 1 times, resulting in a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 2189.2531
Subtracting 79 from 130 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
79 can be fit into 510 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 2189.25316
If we subtract 474 from 510, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
360 divided by 79 is 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 2189.253164
Deduct 316 from 360 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
79 can be fit into 440 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 2189.2531645
Subtracting 395 from 440 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
79 goes into 450 5 times with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 2189.25316455
Subtracting 395 from 450 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 2189.25316455, with a leftover of 5.5e-08.
