20469710 ÷ 870 
Let's see how many times 870 fits into 20469710.

On to step 1:
870 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 870

Let's proceed to step 2:
870 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 870

Moving on to step 3:
If we divide 204 by 870, we get 0 and a remainder of 204.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 204 after subtracting 0 from 204.
Fetch the next digit (6) from the dividend, attach it to 204 and continue: 2046 / 870

On to step 4:
If we divide 2046 by 870, we get 2 and a remainder of 306.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 306 after subtracting 1740 from 2046.
Append the next digit (9) from the dividend to 306 and continue with: 3069 / 870

Advancing to step 5:
The number 870 fits into 3069 3 times, leaving a remainder of 459.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 2610 from 3069 leaves us with 459.
Grab the next digit (7) from the dividend, add it to 459, then carry on: 4597 / 870

Step 6:
870 goes into 4597 5 times with a remainder of 247.
Use 5 as the next digit of our solution. 
Result so far: 235.0
Subtract 4350 from 4597 to get 247.
Take the next digit (1) from the dividend and append it to 247, then repeat: 2471 / 870

Moving on to step 7:
The number 870 fits into 2471 2 times, leaving a remainder of 731.
Record the quotient 2 as the next digit in the result. 
Result so far: 2352.0
If we subtract 1740 from 2471, we get 731.
Fetch the next digit (0) from the dividend, attach it to 731 and continue: 7310 / 870

Step 8:
870 can be fit into 7310 8 times, resulting in a remainder of 350.
Use 8 as the next digit of our solution. 
Result so far: 23528.0
If we take 6960 away from 7310, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 9:
If we divide 3500 by 870, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 23528.4
If we take 3480 away from 3500, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
When dividing 200 by 870, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 23528.4
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
If we divide 2000 by 870, we get 2 and a remainder of 260.
Use 2 as the next digit of our solution. 
Result so far: 23528.402
Subtracting 1740 from 2000 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 12:
If we divide 2600 by 870, we get 2 and a remainder of 860.
Write down 2 as next digit of the result. 
Result so far: 23528.4022
If we take 1740 away from 2600, we end up with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

The final outcome is 23528.4022, with a leftover of 0.0086.
