Let's divide 18586487 by 906
We want to figure out the number of times 18586487 can be divided by 906.

Advancing to step 1:
When dividing 1 by 906, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 906

Advancing to step 2:
The number 906 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 906

Let's proceed to step 3:
When dividing 185 by 906, we get 0 with a remainder of 185.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 185 and we're left with 185.
Append the next digit (8) from the dividend to 185 and continue with: 1858 / 906

Step 4:
906 can be fit into 1858 2 times, resulting in a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1812 from 1858, we get 46.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 906

Going ahead to step 5:
466 divided by 906 is 0 with a remainder of 466.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 466 to get 466.
Append the next digit (4) from the dividend to 466 and continue with: 4664 / 906

Advancing to step 6:
906 can be fit into 4664 5 times, resulting in a remainder of 134.
Use 5 as the next digit of our solution. 
Result so far: 205.0
If we subtract 4530 from 4664, we get 134.
Take the next digit (8) from the dividend and append it to 134, then repeat: 1348 / 906

Moving on to step 7:
The number 906 fits into 1348 1 times, leaving a remainder of 442.
Record the quotient 1 as the next digit in the result. 
Result so far: 2051.0
Subtracting 906 from 1348 leaves us with 442.
Grab the next digit (7) from the dividend, add it to 442, then carry on: 4427 / 906

Going ahead to step 8:
When dividing 4427 by 906, we get 4 with a remainder of 803.
The next digit of our result is 4. 
Result so far: 20514.0
Subtracting 3624 from 4427 leaves us with 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

Advancing to step 9:
906 can be fit into 8030 8 times, resulting in a remainder of 782.
Record the quotient 8 as the next digit in the result. 
Result so far: 20514.8
If we take 7248 away from 8030, we end up with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Moving on to step 10:
7820 divided by 906 is 8 with a remainder of 572.
Record the quotient 8 as the next digit in the result. 
Result so far: 20514.88
The remainder is 572 after subtracting 7248 from 7820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

After the division, we end up with 20514.88 and a remainder of 0.572.
