We divide 18520627 by 870
We want to figure out the number of times 18520627 can be divided by 870.

Advancing to step 1:
When dividing 1 by 870, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 870

Moving on to step 2:
870 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 870

Going ahead to step 3:
When dividing 185 by 870, we get 0 with a remainder of 185.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 185, we get 185.
Include the next digit (2) from the dividend after 185, then repeat: 1852 / 870

Advancing to step 4:
The number 870 fits into 1852 2 times, leaving a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1740 from 1852 and we're left with 112.
Bring next digit (0) of the dividend behind the 112 and repeat the process: 1120 / 870

Moving on to step 5:
870 goes into 1120 1 times with a remainder of 250.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 250 after subtracting 870 from 1120.
Append the next digit (6) from the dividend to 250 and continue with: 2506 / 870

On to step 6:
If we divide 2506 by 870, we get 2 and a remainder of 766.
Write down 2 as next digit of the result. 
Result so far: 212.0
Deduct 1740 from 2506 and we're left with 766.
Take the next digit (2) from the dividend and append it to 766, then repeat: 7662 / 870

Let's proceed to step 7:
870 goes into 7662 8 times with a remainder of 702.
Record the quotient 8 as the next digit in the result. 
Result so far: 2128.0
Deduct 6960 from 7662 and we're left with 702.
Append the next digit (7) from the dividend to 702 and continue with: 7027 / 870

On to step 8:
7027 divided by 870 is 8 with a remainder of 67.
Use 8 as the next digit of our solution. 
Result so far: 21288.0
If we take 6960 away from 7027, 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.

On to step 9:
870 goes into 670 0 times with a remainder of 670.
The number 0 becomes the next digit in our result. 
Result so far: 21288.0
Subtracting 0 from 670 leaves us 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.

Let's proceed to step 10:
If we divide 6700 by 870, we get 7 and a remainder of 610.
The number 7 becomes the next digit in our result. 
Result so far: 21288.07
Subtracting 6090 from 6700 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 11:
870 goes into 6100 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 21288.077
If we subtract 6090 from 6100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 21288.077 and a remainder of 0.001.
