We divide 20505328 by 870
We want to figure out the number of times 20505328 can be divided by 870.

Advancing to step 1:
870 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 870

Advancing to step 2:
870 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 870

Step 3:
205 divided by 870 is 0 with a remainder of 205.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 205 after subtracting 0 from 205.
Bring next digit (0) of the dividend behind the 205 and repeat the process: 2050 / 870

Advancing to step 4:
870 goes into 2050 2 times with a remainder of 310.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1740 from 2050 leaves us with 310.
Bring next digit (5) of the dividend behind the 310 and repeat the process: 3105 / 870

On to step 5:
When dividing 3105 by 870, we get 3 with a remainder of 495.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 2610 away from 3105, we end up with 495.
Fetch the next digit (3) from the dividend, attach it to 495 and continue: 4953 / 870

On to step 6:
4953 divided by 870 is 5 with a remainder of 603.
Put 5 as the next digit of the answer. 
Result so far: 235.0
If we subtract 4350 from 4953, we get 603.
Fetch the next digit (2) from the dividend, attach it to 603 and continue: 6032 / 870

Going ahead to step 7:
When dividing 6032 by 870, we get 6 with a remainder of 812.
The number 6 becomes the next digit in our result. 
Result so far: 2356.0
If we subtract 5220 from 6032, we get 812.
Bring next digit (8) of the dividend behind the 812 and repeat the process: 8128 / 870

On to step 8:
When dividing 8128 by 870, we get 9 with a remainder of 298.
The next digit of our result is 9. 
Result so far: 23569.0
Deduct 7830 from 8128 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 9:
870 can be fit into 2980 3 times, resulting in a remainder of 370.
Record the quotient 3 as the next digit in the result. 
Result so far: 23569.3
Deduct 2610 from 2980 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 10:
When dividing 3700 by 870, we get 4 with a remainder of 220.
The number 4 becomes the next digit in our result. 
Result so far: 23569.34
If we subtract 3480 from 3700, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 11:
If we divide 2200 by 870, we get 2 and a remainder of 460.
Use 2 as the next digit of our solution. 
Result so far: 23569.342
If we take 1740 away from 2200, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 12:
870 goes into 4600 5 times with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 23569.3425
Deduct 4350 from 4600 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 13:
When dividing 2500 by 870, we get 2 with a remainder of 760.
Record the quotient 2 as the next digit in the result. 
Result so far: 23569.34252
If we subtract 1740 from 2500, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 14:
870 can be fit into 7600 8 times, resulting in a remainder of 640.
Record the quotient 8 as the next digit in the result. 
Result so far: 23569.342528
Subtracting 6960 from 7600 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 15:
870 goes into 6400 7 times with a remainder of 310.
Write down 7 as next digit of the result. 
Result so far: 23569.3425287
Deduct 6090 from 6400 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 16:
870 goes into 3100 3 times with a remainder of 490.
Use 3 as the next digit of our solution. 
Result so far: 23569.34252873
Subtract 2610 from 3100 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

In conclusion, the division gives 23569.34252873 with a balance of 4.9e-07.
