2186290 ÷ 986 
We want to figure out the number of times 2186290 can be divided by 986.

Advancing to step 1:
If we divide 2 by 986, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 986

On to step 2:
21 divided by 986 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 986

Advancing to step 3:
218 divided by 986 is 0 with a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 218 to get 218.
Bring next digit (6) of the dividend behind the 218 and repeat the process: 2186 / 986

On to step 4:
If we divide 2186 by 986, we get 2 and a remainder of 214.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1972 from 2186 and we're left with 214.
Include the next digit (2) from the dividend after 214, then repeat: 2142 / 986

Let's proceed to step 5:
986 goes into 2142 2 times with a remainder of 170.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 170 after subtracting 1972 from 2142.
Include the next digit (9) from the dividend after 170, then repeat: 1709 / 986

Moving on to step 6:
The number 986 fits into 1709 1 times, leaving a remainder of 723.
Put 1 as the next digit of the answer. 
Result so far: 221.0
Subtracting 986 from 1709 leaves us with 723.
Take the next digit (0) from the dividend and append it to 723, then repeat: 7230 / 986

On to step 7:
986 can be fit into 7230 7 times, resulting in a remainder of 328.
Record the quotient 7 as the next digit in the result. 
Result so far: 2217.0
If we take 6902 away from 7230, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 8:
When dividing 3280 by 986, we get 3 with a remainder of 322.
The next digit of our result is 3. 
Result so far: 2217.3
If we take 2958 away from 3280, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 9:
3220 divided by 986 is 3 with a remainder of 262.
The number 3 becomes the next digit in our result. 
Result so far: 2217.33
Deduct 2958 from 3220 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

After the division, we end up with 2217.33 and a remainder of 0.262.
