20583115 ÷ 149 
We're looking to find how many times 149 goes into 20583115.

On to step 1:
149 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 149

On to step 2:
If we divide 20 by 149, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 149

Moving on to step 3:
When dividing 205 by 149, we get 1 with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 149 from 205, we get 56.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 149

Advancing to step 4:
The number 149 fits into 568 3 times, leaving a remainder of 121.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 447 from 568 and we're left with 121.
Take the next digit (3) from the dividend and append it to 121, then repeat: 1213 / 149

On to step 5:
149 goes into 1213 8 times with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
The remainder is 21 after subtracting 1192 from 1213.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 149

Moving on to step 6:
149 goes into 211 1 times with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 1381.0
Subtract 149 from 211 to get 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 149

Let's proceed to step 7:
149 can be fit into 621 4 times, resulting in a remainder of 25.
The next digit of our result is 4. 
Result so far: 13814.0
Subtract 596 from 621 to get 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 149

Advancing to step 8:
When dividing 255 by 149, we get 1 with a remainder of 106.
Put 1 as the next digit of the answer. 
Result so far: 138141.0
Subtracting 149 from 255 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 9:
1060 divided by 149 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 138141.7
Deduct 1043 from 1060 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
When dividing 170 by 149, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 138141.71
If we subtract 149 from 170, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
When dividing 210 by 149, we get 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 138141.711
If we take 149 away from 210, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final result is 138141.711 with a remainder of 0.0061.
