172319 ÷ 74 
Our goal is to divide 172319 by 74.

On to step 1:
1 divided by 74 is 0 with 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.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 74

Step 2:
The number 74 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 74

Let's proceed to step 3:
The number 74 fits into 172 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 24 after subtracting 148 from 172.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 74

Let's proceed to step 4:
243 divided by 74 is 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 21 after subtracting 222 from 243.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 74

Going ahead to step 5:
When dividing 211 by 74, we get 2 with a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 232.0
Deduct 148 from 211 and we're left with 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 74

Going ahead to step 6:
If we divide 639 by 74, we get 8 and a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 2328.0
The remainder is 47 after subtracting 592 from 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
If we divide 470 by 74, we get 6 and a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 2328.6
If we subtract 444 from 470, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
260 divided by 74 is 3 with a remainder of 38.
The next digit of our result is 3. 
Result so far: 2328.63
Subtracting 222 from 260 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
The number 74 fits into 380 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 2328.635
The remainder is 10 after subtracting 370 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
When dividing 100 by 74, we get 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 2328.6351
Subtract 74 from 100 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
260 divided by 74 is 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 2328.63513
Deduct 222 from 260 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
When dividing 380 by 74, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 2328.635135
Subtracting 370 from 380 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
74 can be fit into 100 1 times, resulting in a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 2328.6351351
The remainder is 26 after subtracting 74 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
The number 74 fits into 260 3 times, leaving a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 2328.63513513
Deduct 222 from 260 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 2328.63513513 with a remainder of 3.8e-08.
