172859 ÷ 74 
We want to figure out the number of times 172859 can be divided by 74.

Moving on to step 1:
The number 74 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 74

Going ahead to step 2:
74 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 74

Step 3:
74 goes into 172 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 148 from 172 and we're left with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 74

Step 4:
248 divided by 74 is 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 222 from 248 to get 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 74

On to step 5:
265 divided by 74 is 3 with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 233.0
The remainder is 43 after subtracting 222 from 265.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 74

Going ahead to step 6:
439 divided by 74 is 5 with a remainder of 69.
Put 5 as the next digit of the answer. 
Result so far: 2335.0
The remainder is 69 after subtracting 370 from 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 7:
74 can be fit into 690 9 times, resulting in a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 2335.9
Subtracting 666 from 690 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
The number 74 fits into 240 3 times, leaving a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 2335.93
The remainder is 18 after subtracting 222 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
The number 74 fits into 180 2 times, leaving a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 2335.932
Subtract 148 from 180 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
If we divide 320 by 74, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 2335.9324
If we take 296 away from 320, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
74 goes into 240 3 times with a remainder of 18.
The next digit of our result is 3. 
Result so far: 2335.93243
If we take 222 away from 240, 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.

Step 12:
74 goes into 180 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 2335.932432
If we take 148 away from 180, we end up 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.

On to step 13:
320 divided by 74 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 2335.9324324
If we take 296 away from 320, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
74 goes into 240 3 times with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 2335.93243243
If we take 222 away from 240, 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.

The quotient of the division is 2335.93243243, and the remainder is 1.8e-08.
