3423125 ÷ 873 
Let's see how many times 873 fits into 3423125.

Moving on to step 1:
When dividing 3 by 873, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 873

Let's proceed to step 2:
873 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 873

Going ahead to step 3:
873 goes into 342 0 times with a remainder of 342.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 342 and we're left with 342.
Bring next digit (3) of the dividend behind the 342 and repeat the process: 3423 / 873

Step 4:
If we divide 3423 by 873, we get 3 and a remainder of 804.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 2619 from 3423 to get 804.
Fetch the next digit (1) from the dividend, attach it to 804 and continue: 8041 / 873

Advancing to step 5:
When dividing 8041 by 873, we get 9 with a remainder of 184.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 184 after subtracting 7857 from 8041.
Grab the next digit (2) from the dividend, add it to 184, then carry on: 1842 / 873

Step 6:
873 can be fit into 1842 2 times, resulting in a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 392.0
Deduct 1746 from 1842 and we're left with 96.
Grab the next digit (5) from the dividend, add it to 96, then carry on: 965 / 873

Going ahead to step 7:
When dividing 965 by 873, we get 1 with a remainder of 92.
Use 1 as the next digit of our solution. 
Result so far: 3921.0
If we take 873 away from 965, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 8:
If we divide 920 by 873, we get 1 and a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 3921.1
If we subtract 873 from 920, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
470 divided by 873 is 0 with a remainder of 470.
Write down 0 as next digit of the result. 
Result so far: 3921.1
Subtract 0 from 470 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 10:
873 goes into 4700 5 times with a remainder of 335.
Use 5 as the next digit of our solution. 
Result so far: 3921.105
If we subtract 4365 from 4700, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 11:
When dividing 3350 by 873, we get 3 with a remainder of 731.
Use 3 as the next digit of our solution. 
Result so far: 3921.1053
Subtracting 2619 from 3350 leaves us with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Step 12:
When dividing 7310 by 873, we get 8 with a remainder of 326.
Use 8 as the next digit of our solution. 
Result so far: 3921.10538
The remainder is 326 after subtracting 6984 from 7310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 13:
873 can be fit into 3260 3 times, resulting in a remainder of 641.
The number 3 becomes the next digit in our result. 
Result so far: 3921.105383
Deduct 2619 from 3260 and we're left with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Let's proceed to step 14:
When dividing 6410 by 873, we get 7 with a remainder of 299.
Record the quotient 7 as the next digit in the result. 
Result so far: 3921.1053837
Deduct 6111 from 6410 and we're left with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 15:
2990 divided by 873 is 3 with a remainder of 371.
Put 3 as the next digit of the answer. 
Result so far: 3921.10538373
Deduct 2619 from 2990 and we're left with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

After the division, we end up with 3921.10538373 and a remainder of 3.71e-07.
