We look at the division of 20258580 by 181 
We want to divide 20258580 by 181.

Step 1:
If we divide 2 by 181, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 181

Moving on to step 2:
If we divide 20 by 181, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 181

Advancing to step 3:
202 divided by 181 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 181 from 202 to get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 181

Step 4:
215 divided by 181 is 1 with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 181 from 215, we get 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 181

Going ahead to step 5:
181 can be fit into 348 1 times, resulting in a remainder of 167.
Use 1 as the next digit of our solution. 
Result so far: 111.0
The remainder is 167 after subtracting 181 from 348.
Include the next digit (5) from the dividend after 167, then repeat: 1675 / 181

On to step 6:
If we divide 1675 by 181, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 1119.0
Subtract 1629 from 1675 to get 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 181

Step 7:
When dividing 468 by 181, we get 2 with a remainder of 106.
Write down 2 as next digit of the result. 
Result so far: 11192.0
If we take 362 away from 468, we end up with 106.
Fetch the next digit (0) from the dividend, attach it to 106 and continue: 1060 / 181

Moving on to step 8:
1060 divided by 181 is 5 with a remainder of 155.
The next digit of our result is 5. 
Result so far: 111925.0
Deduct 905 from 1060 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 9:
If we divide 1550 by 181, we get 8 and a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 111925.8
If we subtract 1448 from 1550, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 10:
The number 181 fits into 1020 5 times, leaving a remainder of 115.
The next digit of our result is 5. 
Result so far: 111925.85
Deduct 905 from 1020 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 11:
When dividing 1150 by 181, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 111925.856
The remainder is 64 after subtracting 1086 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
181 can be fit into 640 3 times, resulting in a remainder of 97.
Write down 3 as next digit of the result. 
Result so far: 111925.8563
If we take 543 away from 640, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 13:
181 goes into 970 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 111925.85635
The remainder is 65 after subtracting 905 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 14:
When dividing 650 by 181, we get 3 with a remainder of 107.
Use 3 as the next digit of our solution. 
Result so far: 111925.856353
If we subtract 543 from 650, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 15:
181 can be fit into 1070 5 times, resulting in a remainder of 165.
The next digit of our result is 5. 
Result so far: 111925.8563535
If we subtract 905 from 1070, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 16:
181 goes into 1650 9 times with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 111925.85635359
Subtracting 1629 from 1650 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 111925.85635359 with a remaining 2.1e-08.
