We're dividing 20980025 by 136 
We're looking to find how many times 136 goes into 20980025.

Going ahead to step 1:
136 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 136

Step 2:
136 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 136

Going ahead to step 3:
If we divide 209 by 136, we get 1 and a remainder of 73.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 136 from 209, we get 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 136

Let's proceed to step 4:
738 divided by 136 is 5 with a remainder of 58.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 680 away from 738, we end up with 58.
Take the next digit (0) from the dividend and append it to 58, then repeat: 580 / 136

Let's proceed to step 5:
When dividing 580 by 136, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 154.0
Deduct 544 from 580 and we're left with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 136

Going ahead to step 6:
136 can be fit into 360 2 times, resulting in a remainder of 88.
The next digit of our result is 2. 
Result so far: 1542.0
If we take 272 away from 360, we end up with 88.
Append the next digit (2) from the dividend to 88 and continue with: 882 / 136

Going ahead to step 7:
The number 136 fits into 882 6 times, leaving a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 15426.0
Deduct 816 from 882 and we're left with 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 136

Step 8:
136 can be fit into 665 4 times, resulting in a remainder of 121.
Put 4 as the next digit of the answer. 
Result so far: 154264.0
Deduct 544 from 665 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 9:
If we divide 1210 by 136, we get 8 and a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 154264.8
Deduct 1088 from 1210 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 10:
136 goes into 1220 8 times with a remainder of 132.
Write down 8 as next digit of the result. 
Result so far: 154264.88
If we take 1088 away from 1220, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final outcome is 154264.88, with a leftover of 0.132.
