20517430 ÷ 873 
Let's see how many times 873 fits into 20517430.

Going ahead to step 1:
If we divide 2 by 873, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 873

Advancing to step 2:
873 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 873

Moving on to step 3:
873 goes into 205 0 times with a remainder of 205.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 205, we end up with 205.
Take the next digit (1) from the dividend and append it to 205, then repeat: 2051 / 873

Advancing to step 4:
The number 873 fits into 2051 2 times, leaving a remainder of 305.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1746 from 2051, we get 305.
Include the next digit (7) from the dividend after 305, then repeat: 3057 / 873

Moving on to step 5:
When dividing 3057 by 873, we get 3 with a remainder of 438.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 2619 from 3057, we get 438.
Fetch the next digit (4) from the dividend, attach it to 438 and continue: 4384 / 873

Going ahead to step 6:
4384 divided by 873 is 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 235.0
If we take 4365 away from 4384, we end up with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 873

Advancing to step 7:
If we divide 193 by 873, we get 0 and a remainder of 193.
The next digit of our result is 0. 
Result so far: 2350.0
The remainder is 193 after subtracting 0 from 193.
Append the next digit (0) from the dividend to 193 and continue with: 1930 / 873

Advancing to step 8:
873 goes into 1930 2 times with a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 23502.0
Subtract 1746 from 1930 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 9:
873 goes into 1840 2 times with a remainder of 94.
The number 2 becomes the next digit in our result. 
Result so far: 23502.2
The remainder is 94 after subtracting 1746 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
The number 873 fits into 940 1 times, leaving a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 23502.21
If we take 873 away from 940, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 11:
When dividing 670 by 873, we get 0 with a remainder of 670.
Write down 0 as next digit of the result. 
Result so far: 23502.21
If we take 0 away from 670, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 12:
873 can be fit into 6700 7 times, resulting in a remainder of 589.
The number 7 becomes the next digit in our result. 
Result so far: 23502.2107
If we take 6111 away from 6700, we end up with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Step 13:
873 goes into 5890 6 times with a remainder of 652.
Use 6 as the next digit of our solution. 
Result so far: 23502.21076
If we take 5238 away from 5890, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Moving on to step 14:
If we divide 6520 by 873, we get 7 and a remainder of 409.
Put 7 as the next digit of the answer. 
Result so far: 23502.210767
If we subtract 6111 from 6520, we get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 15:
873 goes into 4090 4 times with a remainder of 598.
Write down 4 as next digit of the result. 
Result so far: 23502.2107674
The remainder is 598 after subtracting 3492 from 4090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Moving on to step 16:
873 can be fit into 5980 6 times, resulting in a remainder of 742.
Record the quotient 6 as the next digit in the result. 
Result so far: 23502.21076746
If we subtract 5238 from 5980, we get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

In conclusion, the division gives 23502.21076746 with a balance of 7.42e-07.
