We look at the division of 22587943 by 870 
We're looking to find how many times 870 goes into 22587943.

Going ahead to step 1:
If we divide 2 by 870, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 870

Step 2:
If we divide 22 by 870, we get 0 and a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 870

Let's proceed to step 3:
If we divide 225 by 870, we get 0 and a remainder of 225.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 225 leaves us with 225.
Take the next digit (8) from the dividend and append it to 225, then repeat: 2258 / 870

Let's proceed to step 4:
870 goes into 2258 2 times with a remainder of 518.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1740 from 2258 to get 518.
Include the next digit (7) from the dividend after 518, then repeat: 5187 / 870

Going ahead to step 5:
If we divide 5187 by 870, we get 5 and a remainder of 837.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 837 after subtracting 4350 from 5187.
Include the next digit (9) from the dividend after 837, then repeat: 8379 / 870

Advancing to step 6:
870 can be fit into 8379 9 times, resulting in a remainder of 549.
The number 9 becomes the next digit in our result. 
Result so far: 259.0
The remainder is 549 after subtracting 7830 from 8379.
Append the next digit (4) from the dividend to 549 and continue with: 5494 / 870

Step 7:
870 can be fit into 5494 6 times, resulting in a remainder of 274.
Put 6 as the next digit of the answer. 
Result so far: 2596.0
Subtracting 5220 from 5494 leaves us with 274.
Include the next digit (3) from the dividend after 274, then repeat: 2743 / 870

Advancing to step 8:
When dividing 2743 by 870, we get 3 with a remainder of 133.
The next digit of our result is 3. 
Result so far: 25963.0
Subtract 2610 from 2743 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 9:
When dividing 1330 by 870, we get 1 with a remainder of 460.
Put 1 as the next digit of the answer. 
Result so far: 25963.1
If we take 870 away from 1330, 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.

On to step 10:
870 goes into 4600 5 times with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 25963.15
The remainder is 250 after subtracting 4350 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 11:
The number 870 fits into 2500 2 times, leaving a remainder of 760.
Record the quotient 2 as the next digit in the result. 
Result so far: 25963.152
The remainder is 760 after subtracting 1740 from 2500.
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 12:
870 can be fit into 7600 8 times, resulting in a remainder of 640.
The next digit of our result is 8. 
Result so far: 25963.1528
Deduct 6960 from 7600 and we're left 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.

Let's proceed to step 13:
If we divide 6400 by 870, we get 7 and a remainder of 310.
Write down 7 as next digit of the result. 
Result so far: 25963.15287
If we subtract 6090 from 6400, we get 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 14:
If we divide 3100 by 870, we get 3 and a remainder of 490.
The next digit of our result is 3. 
Result so far: 25963.152873
Subtracting 2610 from 3100 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 15:
870 can be fit into 4900 5 times, resulting in a remainder of 550.
The next digit of our result is 5. 
Result so far: 25963.1528735
Deduct 4350 from 4900 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 16:
5500 divided by 870 is 6 with a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 25963.15287356
The remainder is 280 after subtracting 5220 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The quotient of the division is 25963.15287356, and the remainder is 2.8e-07.
